+Valid Range:   0,1,3,100-100000 (0=off, 1=dynamic, 3=dynamic conservative)
+Default Value: 3
+
+The driver can limit the amount of interrupts per second that the adapter
+will generate for incoming packets. It does this by writing a value to the 
+adapter that is based on the maximum amount of interrupts that the adapter 
+will generate per second.
+
+Setting InterruptThrottleRate to a value greater or equal to 100
+will program the adapter to send out a maximum of that many interrupts
+per second, even if more packets have come in. This reduces interrupt
+load on the system and can lower CPU utilization under heavy load,
+but will increase latency as packets are not processed as quickly.
+
+The default behaviour of the driver previously assumed a static 
+InterruptThrottleRate value of 8000, providing a good fallback value for 
+all traffic types,but lacking in small packet performance and latency. 
+The hardware can handle many more small packets per second however, and 
+for this reason an adaptive interrupt moderation algorithm was implemented.
+
+Since 7.3.x, the driver has two adaptive modes (setting 1 or 3) in which
+it dynamically adjusts the InterruptThrottleRate value based on the traffic 
+that it receives. After determining the type of incoming traffic in the last
+timeframe, it will adjust the InterruptThrottleRate to an appropriate value 
+for that traffic.
+
+The algorithm classifies the incoming traffic every interval into
+classes.  Once the class is determined, the InterruptThrottleRate value is 
+adjusted to suit that traffic type the best. There are three classes defined: 
+"Bulk traffic", for large amounts of packets of normal size; "Low latency",
+for small amounts of traffic and/or a significant percentage of small
+packets; and "Lowest latency", for almost completely small packets or 
+minimal traffic.
+
+In dynamic conservative mode, the InterruptThrottleRate value is set to 4000 
+for traffic that falls in class "Bulk traffic". If traffic falls in the "Low 
+latency" or "Lowest latency" class, the InterruptThrottleRate is increased 
+stepwise to 20000. This default mode is suitable for most applications.
+
+For situations where low latency is vital such as cluster or
+grid computing, the algorithm can reduce latency even more when
+InterruptThrottleRate is set to mode 1. In this mode, which operates
+the same as mode 3, the InterruptThrottleRate will be increased stepwise to 
+70000 for traffic in class "Lowest latency".
+
+Setting InterruptThrottleRate to 0 turns off any interrupt moderation
+and may improve small packet latency, but is generally not suitable
+for bulk throughput traffic.
 
 NOTE:  InterruptThrottleRate takes precedence over the TxAbsIntDelay and
-       RxAbsIntDelay parameters. In other words, minimizing the receive
+       RxAbsIntDelay parameters.  In other words, minimizing the receive
        and/or transmit absolute delays does not force the controller to

-  (non-partitioned switch) behave as expected. All Ethernet interfaces
-  will respond to IP traffic for any IP address assigned to the system.
-  This results in unbalanced receive traffic.
-
-  If you have multiple interfaces in a server, either turn on ARP
-  filtering by entering:
-
-      echo 1 > /proc/sys/net/ipv4/conf/all/arp_filter
-  (this only works if your kernel's version is higher than 2.4.5),
-
-  NOTE: This setting is not saved across reboots. The configuration
-  change can be made permanent by adding the line:
-      net.ipv4.conf.all.arp_filter = 1
-  to the file /etc/sysctl.conf
-
-        or,
-
-  install the interfaces in separate broadcast domains (either in
-  different switches or in a switch partitioned to VLANs).

-  82541/82547 can't link or are slow to link with some link partners

-

-  low-end switches where the link will not be established, or will
-  be slow to establish.  In particular, these switches are known to

-
-      0 = Hardware default
-      1 = Master mode
-      2 = Slave mode
-      3 = Auto master/slave
-
-  Disable rx flow control with ethtool
-  ------------------------------------
-
-  In order to disable receive flow control using ethtool, you must turn
-  off auto-negotiation on the same command line.
-
-  For example:
-
-     ethtool -A eth? autoneg off rx off
+Dropped Receive Packets on Half-duplex 10/100 Networks
+------------------------------------------------------
+If you have an Intel PCI Express adapter running at 10mbps or 100mbps, half-
+duplex, you may observe occasional dropped receive packets.  There are no
+workarounds for this problem in this network configuration.  The network must
+be updated to operate in full-duplex, and/or 1000mbps only.
+
+Jumbo Frames System Requirement
+-------------------------------
+Memory allocation failures have been observed on Linux systems with 64 MB
+of RAM or less that are running Jumbo Frames.  If you are using Jumbo
+Frames, your system may require more than the advertised minimum
+requirement of 64 MB of system memory.
+
+Performance Degradation with Jumbo Frames
+-----------------------------------------
+Degradation in throughput performance may be observed in some Jumbo frames
+environments.  If this is observed, increasing the application's socket
+buffer size and/or increasing the /proc/sys/net/ipv4/tcp_*mem entry values
+may help.  See the specific application manual and
+/usr/src/linux*/Documentation/
+networking/ip-sysctl.txt for more details.
+
+Jumbo Frames on Foundry BigIron 8000 switch
+-------------------------------------------
+There is a known issue using Jumbo frames when connected to a Foundry
+BigIron 8000 switch.  This is a 3rd party limitation.  If you experience
+loss of packets, lower the MTU size.
+
+Allocating Rx Buffers when Using Jumbo Frames 
+---------------------------------------------
+Allocating Rx buffers when using Jumbo Frames on 2.6.x kernels may fail if 
+the available memory is heavily fragmented. This issue may be seen with PCI-X 
+adapters or with packet split disabled. This can be reduced or eliminated 
+by changing the amount of available memory for receive buffer allocation, by
+increasing /proc/sys/vm/min_free_kbytes. 
+
+Multiple Interfaces on Same Ethernet Broadcast Network
+------------------------------------------------------
+Due to the default ARP behavior on Linux, it is not possible to have
+one system on two IP networks in the same Ethernet broadcast domain
+(non-partitioned switch) behave as expected.  All Ethernet interfaces
+will respond to IP traffic for any IP address assigned to the system.
+This results in unbalanced receive traffic.
+
+If you have multiple interfaces in a server, either turn on ARP
+filtering by entering:
+
+    echo 1 > /proc/sys/net/ipv4/conf/all/arp_filter

+change can be made permanent by adding the line:
+    net.ipv4.conf.all.arp_filter = 1

+
+Where <n> is:
+
+    0 = Hardware default
+    1 = Master mode
+    2 = Slave mode
+    3 = Auto master/slave
+
+Disable rx flow control with ethtool
+------------------------------------
+In order to disable receive flow control using ethtool, you must turn
+off auto-negotiation on the same command line.
+
+For example:
+
+   ethtool -A eth? autoneg off rx off
+
+Unplugging network cable while ethtool -p is running
+----------------------------------------------------
+In kernel versions 2.5.50 and later (including 2.6 kernel), unplugging
+the network cable while ethtool -p is running will cause the system to
+become unresponsive to keyboard commands, except for control-alt-delete.
+Restarting the system appears to be the only remedy.

-  This is the chip-specific code for many 8390-based ethernet adaptors.
-  This is not a complete driver, it must be combined with board-specific
-  code such as ne.c, wd.c, 3c503.c, etc.
-
-  Seeing how at least eight drivers use this code, (not counting the
-  PCMCIA ones either) it is easy to break some card by what seems like
-  a simple innocent change. Please contact me or Donald if you think
-  you have found something that needs changing. -- PG
-
-
-  Changelog:
-
-  Paul Gortmaker	: remove set_bit lock, other cleanups.
-  Paul Gortmaker	: add ei_get_8390_hdr() so we can pass skb's to
-			  ei_block_input() for eth_io_copy_and_sum().
-  Paul Gortmaker	: exchange static int ei_pingpong for a #define,
-			  also add better Tx error handling.
-  Paul Gortmaker	: rewrite Rx overrun handling as per NS specs.
-  Alexey Kuznetsov	: use the 8390's six bit hash multicast filter.
-  Paul Gortmaker	: tweak ANK's above multicast changes a bit.
-  Paul Gortmaker	: update packet statistics for v2.1.x
-  Alan Cox		: support arbitary stupid port mappings on the
-  			  68K Macintosh. Support >16bit I/O spaces
-  Paul Gortmaker	: add kmod support for auto-loading of the 8390
-			  module by all drivers that require it.
-  Alan Cox		: Spinlocking work, added 'BUG_83C690'
-  Paul Gortmaker	: Separate out Tx timeout code from Tx path.
-  Paul Gortmaker	: Remove old unused single Tx buffer code.
-  Hayato Fujiwara	: Add m32r support.
-  Paul Gortmaker	: use skb_padto() instead of stack scratch area

+
+  This is the chip-specific code for many 8390-based ethernet adaptors.
+  This is not a complete driver, it must be combined with board-specific
+  code such as ne.c, wd.c, 3c503.c, etc.
+
+  Seeing how at least eight drivers use this code, (not counting the
+  PCMCIA ones either) it is easy to break some card by what seems like
+  a simple innocent change. Please contact me or Donald if you think
+  you have found something that needs changing. -- PG
+
+
+  Changelog:
+
+  Paul Gortmaker	: remove set_bit lock, other cleanups.
+  Paul Gortmaker	: add ei_get_8390_hdr() so we can pass skb's to
+			  ei_block_input() for eth_io_copy_and_sum().
+  Paul Gortmaker	: exchange static int ei_pingpong for a #define,
+			  also add better Tx error handling.
+  Paul Gortmaker	: rewrite Rx overrun handling as per NS specs.
+  Alexey Kuznetsov	: use the 8390's six bit hash multicast filter.
+  Paul Gortmaker	: tweak ANK's above multicast changes a bit.
+  Paul Gortmaker	: update packet statistics for v2.1.x
+  Alan Cox		: support arbitary stupid port mappings on the
+  			  68K Macintosh. Support >16bit I/O spaces
+  Paul Gortmaker	: add kmod support for auto-loading of the 8390
+			  module by all drivers that require it.
+  Alan Cox		: Spinlocking work, added 'BUG_83C690'
+  Paul Gortmaker	: Separate out Tx timeout code from Tx path.
+  Paul Gortmaker	: Remove old unused single Tx buffer code.
+  Hayato Fujiwara	: Add m32r support.
+  Paul Gortmaker	: use skb_padto() instead of stack scratch area

+ *	To make life difficult the chip can also be very slow. We therefore can't

+ *	processor case other than interrupts (get stats/set multicast list in
+ *	parallel with each other and transmit).
+ *
+ *	Note: in theory we can just disable the irq on the card _but_ there is
+ *	a latency on SMP irq delivery. So we can easily go "disable irq" "sync irqs"
+ *	enter lock, take the queued irq. So we waddle instead of flying.
