  5559. * 1. First PF driver which loads on a path will:

  5567. * PGLUE_B_REG_INTERNAL_PFID_ENABLE_MASTER to enable
  5568. * dmae-operations (writing to pram for example.)
  5569. * note: can be done for only function 6,7 but cleaner this
  5570. * way.
  5571. * b. Write zero+valid to the entire ILT.
  5572. * c. Init the first_timers_ilt_entry, last_timers_ilt_entry of
  5573. * VNIC3 (of that port). The range allocated will be the
  5574. * entire ILT. This is needed to prevent ILT range error.
  5575. * 2. Any PF driver load flow:
  5576. * a. ILT update with the physical addresses of the allocated
  5577. * logical pages.
  5578. * b. Wait 20msec. - note that this timeout is needed to make
  5579. * sure there are no requests in one of the PXP internal
  5580. * queues with "old" ILT addresses.
  5581. * c. PF enable in the PGLC.
  5582. * d. Clear the was_error of the PF in the PGLC. (could have
  5583. * occurred while driver was down)
  5584. * e. PF enable in the CFC (WEAK + STRONG)
  5585. * f. Timers scan enable
  5586. * 3. PF driver unload flow:
  5587. * a. Clear the Timers scan_en.
  5588. * b. Polling for scan_on=0 for that PF.
  5589. * c. Clear the PF enable bit in the PXP.
  5590. * d. Clear the PF enable in the CFC (WEAK + STRONG)
  5591. * e. Write zero+valid to all ILT entries (The valid bit must
  5592. * stay set)
  5593. * f. If this is VNIC 3 of a port then also init
  5594. * first_timers_ilt_entry to zero and last_timers_ilt_entry
  5595. * to the last enrty in the ILT.
  5596. *
  5597. * Notes:
  5598. * Currently the PF error in the PGLC is non recoverable.
  5599. * In the future the there will be a recovery routine for this error.
  5600. * Currently attention is masked.
  5601. * Having an MCP lock on the load/unload process does not guarantee that
  5602. * there is no Timer disable during Func6/7 enable. This is because the
  5603. * Timers scan is currently being cleared by the MCP on FLR.
  5604. * Step 2.d can be done only for PF6/7 and the driver can also check if
  5605. * there is error before clearing it. But the flow above is simpler and
  5606. * more general.
  5607. * All ILT entries are written by zero+valid and not just PF6/7
