6393 * dmae-operations (writing to pram for example.)
6394 * note: can be done for only function 6,7 but cleaner this
6396 * b. Write zero+valid to the entire ILT.
6397 * c. Init the first_timers_ilt_entry, last_timers_ilt_entry of
6398 * VNIC3 (of that port). The range allocated will be the
6399 * entire ILT. This is needed to prevent ILT range error.
6400 * 2. Any PF driver load flow:
6401 * a. ILT update with the physical addresses of the allocated
6403 * b. Wait 20msec. - note that this timeout is needed to make
6404 * sure there are no requests in one of the PXP internal
6405 * queues with "old" ILT addresses.
6406 * c. PF enable in the PGLC.
6407 * d. Clear the was_error of the PF in the PGLC. (could have
6408 * occured while driver was down)
6409 * e. PF enable in the CFC (WEAK + STRONG)
6410 * f. Timers scan enable
6411 * 3. PF driver unload flow:
6412 * a. Clear the Timers scan_en.
6413 * b. Polling for scan_on=0 for that PF.
6414 * c. Clear the PF enable bit in the PXP.
6415 * d. Clear the PF enable in the CFC (WEAK + STRONG)
6416 * e. Write zero+valid to all ILT entries (The valid bit must
6418 * f. If this is VNIC 3 of a port then also init
6419 * first_timers_ilt_entry to zero and last_timers_ilt_entry
6420 * to the last enrty in the ILT.

6426 * Having an MCP lock on the load/unload process does not guarantee that
6427 * there is no Timer disable during Func6/7 enable. This is because the
6428 * Timers scan is currently being cleared by the MCP on FLR.
6429 * Step 2.d can be done only for PF6/7 and the driver can also check if
6430 * there is error before clearing it. But the flow above is simpler and
6432 * All ILT entries are written by zero+valid and not just PF6/7
