5834 * 1. First PF driver which loads on a path will:

5843 * dmae-operations (writing to pram for example.)
5844 * note: can be done for only function 6,7 but cleaner this
5846 * b. Write zero+valid to the entire ILT.
5847 * c. Init the first_timers_ilt_entry, last_timers_ilt_entry of
5848 * VNIC3 (of that port). The range allocated will be the
5849 * entire ILT. This is needed to prevent ILT range error.
5850 * 2. Any PF driver load flow:
5851 * a. ILT update with the physical addresses of the allocated
5853 * b. Wait 20msec. - note that this timeout is needed to make
5854 * sure there are no requests in one of the PXP internal
5855 * queues with "old" ILT addresses.
5856 * c. PF enable in the PGLC.
5857 * d. Clear the was_error of the PF in the PGLC. (could have
5858 * occured while driver was down)
5859 * e. PF enable in the CFC (WEAK + STRONG)
5860 * f. Timers scan enable
5861 * 3. PF driver unload flow:
5862 * a. Clear the Timers scan_en.
5863 * b. Polling for scan_on=0 for that PF.
5864 * c. Clear the PF enable bit in the PXP.
5865 * d. Clear the PF enable in the CFC (WEAK + STRONG)
5866 * e. Write zero+valid to all ILT entries (The valid bit must
5868 * f. If this is VNIC 3 of a port then also init
5869 * first_timers_ilt_entry to zero and last_timers_ilt_entry
5870 * to the last enrty in the ILT.
5873 * Currently the PF error in the PGLC is non recoverable.
5874 * In the future the there will be a recovery routine for this error.
5875 * Currently attention is masked.
5876 * Having an MCP lock on the load/unload process does not guarantee that
5877 * there is no Timer disable during Func6/7 enable. This is because the
5878 * Timers scan is currently being cleared by the MCP on FLR.
5879 * Step 2.d can be done only for PF6/7 and the driver can also check if
5880 * there is error before clearing it. But the flow above is simpler and
5882 * All ILT entries are written by zero+valid and not just PF6/7
5883 * ILT entries since in the future the ILT entries allocation for
5884 * PF-s might be dynamic.
