- Introduce FC credit recovery. - Added module parameter to enable/disable credit recovery. Bug Fixes: - Removed check for ignoring plogi from initiator in switched fabric mode. - The ABTS for PLOGI is going out few millisecs earlier due to FW timer calibration (around 300 miilisecs earlier). So there is a window if an accept comes during this time HBA would have initiated an ABORT. - Added 1 to FC_ELS_TOV for compensating for FW timer.
