6642 * load-unloaded while func6,7 are down. This will cause the timer to access
6643 * the ilt, translate to a logical address and send a request to read/write.
6644 * Since the ilt for the function that is down is not valid, this will cause
6645 * a translation error which is unrecoverable.
6646 * The Workaround is intended to make sure that when this happens nothing fatal
6647 * will occur. The workaround:
6648 * 1. First PF driver which loads on a path will:
6649 * a. After taking the chip out of reset, by using pretend,
6650 * it will write "0" to the following registers of
6651 * the other vnics.

6653 * REG_WR(pdev, CFC_REG_WEAK_ENABLE_PF,0);

6655 * And for itself it will write '1' to
6656 * PGLUE_B_REG_INTERNAL_PFID_ENABLE_MASTER to enable
6657 * dmae-operations (writing to pram for example.)
6658 * note: can be done for only function 6,7 but cleaner this
6659 * way.
6660 * b. Write zero+valid to the entire ILT.
6661 * c. Init the first_timers_ilt_entry, last_timers_ilt_entry of
6662 * VNIC3 (of that port). The range allocated will be the
6663 * entire ILT. This is needed to prevent ILT range error.
6664 * 2. Any PF driver load flow:
6665 * a. ILT update with the physical addresses of the allocated
6666 * logical pages.
6667 * b. Wait 20msec. - note that this timeout is needed to make
6668 * sure there are no requests in one of the PXP internal
6669 * queues with "old" ILT addresses.
6670 * c. PF enable in the PGLC.
6671 * d. Clear the was_error of the PF in the PGLC. (could have
6672 * occurred while driver was down)
6673 * e. PF enable in the CFC (WEAK + STRONG)
6674 * f. Timers scan enable
6675 * 3. PF driver unload flow:
6676 * a. Clear the Timers scan_en.
6677 * b. Polling for scan_on=0 for that PF.
6678 * c. Clear the PF enable bit in the PXP.
6679 * d. Clear the PF enable in the CFC (WEAK + STRONG)
6680 * e. Write zero+valid to all ILT entries (The valid bit must
6681 * stay set)
6682 * f. If this is VNIC 3 of a port then also init
6683 * first_timers_ilt_entry to zero and last_timers_ilt_entry
6684 * to the last enrty in the ILT.
6685 *
6686 * Notes:
6687 * Currently the PF error in the PGLC is non recoverable.
6688 * In the future the there will be a recovery routine for this error.
6689 * Currently attention is masked.
6690 * Having an MCP lock on the load/unload process does not guarantee that
6691 * there is no Timer disable during Func6/7 enable. This is because the
6692 * Timers scan is currently being cleared by the MCP on FLR.
6693 * Step 2.d can be done only for PF6/7 and the driver can also check if
6694 * there is error before clearing it. But the flow above is simpler and
6695 * more general.
6696 * All ILT entries are written by zero+valid and not just PF6/7
6697 * ILT entries since in the future the ILT entries allocation for
6698 * PF-s might be dynamic.
