6409 * dmae-operations (writing to pram for example.)
6410 * note: can be done for only function 6,7 but cleaner this
6412 * b. Write zero+valid to the entire ILT.
6413 * c. Init the first_timers_ilt_entry, last_timers_ilt_entry of
6414 * VNIC3 (of that port). The range allocated will be the
6415 * entire ILT. This is needed to prevent ILT range error.
6416 * 2. Any PF driver load flow:
6417 * a. ILT update with the physical addresses of the allocated
6419 * b. Wait 20msec. - note that this timeout is needed to make
6420 * sure there are no requests in one of the PXP internal
6421 * queues with "old" ILT addresses.
6422 * c. PF enable in the PGLC.
6423 * d. Clear the was_error of the PF in the PGLC. (could have
6424 * occured while driver was down)
6425 * e. PF enable in the CFC (WEAK + STRONG)
6426 * f. Timers scan enable
6427 * 3. PF driver unload flow:
6428 * a. Clear the Timers scan_en.
6429 * b. Polling for scan_on=0 for that PF.
6430 * c. Clear the PF enable bit in the PXP.
6431 * d. Clear the PF enable in the CFC (WEAK + STRONG)
6432 * e. Write zero+valid to all ILT entries (The valid bit must
6434 * f. If this is VNIC 3 of a port then also init
6435 * first_timers_ilt_entry to zero and last_timers_ilt_entry
6436 * to the last enrty in the ILT.

6445 * Step 2.d can be done only for PF6/7 and the driver can also check if
6446 * there is error before clearing it. But the flow above is simpler and
6448 * All ILT entries are written by zero+valid and not just PF6/7
