  335. (preliminary merge to U-Boot, still WIP)
  336. * Patch by Jon Diekema, 12 Nov 2002:
  337. - Adding URL for IEEE OUI lookup
  338. - Making the autoboot #defines dependent on CONFIG_AUTOBOOT_KEYED
  339. being defined.
  340. - In the CONFIG_EXTRA_ENV_SETTINGS #define, the root-on-initrd and
  341. root-on-nfs macros are designed to switch how the default boot
  342. method gets defined.

  347. * Patch by Jim Sandoz, 07 Nov 2002:
  348. Increase number of network RX buffers (PKTBUFSRX in
  349. "include/net.h") for EEPRO100 based boards (especially SP8240)
  350. which showed "Receiver is not ready" errors when U-Boot was
  351. processing the receive buffers slower than the network controller
  352. was filling them.
  353. * Patch by Andreas Oberritter, 09 Nov 2002:
  354. Change behaviour of NetLoop(): return -1 for errors, filesize
  355. otherwise; return code 0 is valid an means no file loaded - in this
  356. case the environment still gets updated!

  363. handlering
