| | | | | | | | | | | | | | | Fix the FLOGI discovery logic to comply with T11 standards We weren't properly setting fabric parameters, such as R_A_TOV and E_D_TOV, when we registered the vfi object in default configs and pt2pt configs.

* lpfc: Fix premature release of rpi bit in bitmaskJames Smart2015-04-101-0/+5
| | | | | | | | | | | | | | | | Currently, the driver plays off the fact that older sli4 adapters have a different rpi access pattern that allowed for the rpi reference to be released earlier in the teardown sequence, allowing the driver to recycle the rpi value sooner. Newer sli4 adapters have a different access pattern that requires us to wait for a later mailbox completion. This changes the put call location on the newer sli4 adapters. Symptoms of the error are "0110 ELS" and the "0372 iotag" errors.
