5951

5957
* 1. First PF driver which loads on a path will:
5958

5965
* PGLUE_B_REG_INTERNAL_PFID_ENABLE_MASTER to enable
5966
* dmae-operations (writing to pram for example.)
5967
* note: can be done for only function 6,7 but cleaner this
5969
* b. Write zero+valid to the entire ILT.
5970
* c. Init the first_timers_ilt_entry, last_timers_ilt_entry of
5971
* VNIC3 (of that port). The range allocated will be the
5972
* entire ILT. This is needed to prevent ILT range error.
5973
* 2. Any PF driver load flow:
5974
* a. ILT update with the physical addresses of the allocated
5976
* b. Wait 20msec. - note that this timeout is needed to make
5977
* sure there are no requests in one of the PXP internal
5978
* queues with "old" ILT addresses.
5979
* c. PF enable in the PGLC.
5980
* d. Clear the was_error of the PF in the PGLC. (could have
5981
* occured while driver was down)
5982
* e. PF enable in the CFC (WEAK + STRONG)
5983
* f. Timers scan enable
5984
* 3. PF driver unload flow:
5985
* a. Clear the Timers scan_en.
5986
* b. Polling for scan_on=0 for that PF.
5987
* c. Clear the PF enable bit in the PXP.
5988
* d. Clear the PF enable in the CFC (WEAK + STRONG)
5989
* e. Write zero+valid to all ILT entries (The valid bit must
5991
* f. If this is VNIC 3 of a port then also init
5992
* first_timers_ilt_entry to zero and last_timers_ilt_entry
5993
* to the last enrty in the ILT.
5996
* Currently the PF error in the PGLC is non recoverable.
5997
* In the future the there will be a recovery routine for this error.
5998
* Currently attention is masked.
5999
* Having an MCP lock on the load/unload process does not guarantee that
6000
* there is no Timer disable during Func6/7 enable. This is because the
6001
* Timers scan is currently being cleared by the MCP on FLR.
6002
* Step 2.d can be done only for PF6/7 and the driver can also check if
6003
* there is error before clearing it. But the flow above is simpler and
6005
* All ILT entries are written by zero+valid and not just PF6/7
6006
* ILT entries since in the future the ILT entries allocation for
6007
