From: James Smart Date: Tue, 11 Oct 2011 01:32:10 +0000 (-0400) Subject: [SCSI] lpfc 8.3.27: Miscellanous logic and interface fixes X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=73d91e503a60bd164b636258ae9f558b72010602;p=linux-beck.git [SCSI] lpfc 8.3.27: Miscellanous logic and interface fixes Miscellanous logic and interface fixes - Fix lpfc_init_vfi_cmpl to check the interface type for interface type 0 before parsing the results. - Cast uint32_t values that are multiplied to uint64_t before the multiplication. - Instead of "break" statement when PCI read returned error, use the goto statement to the end of the routine after setting return value - moved the msleep(10) to the beginning of the wait loop for checking the SLIPort_Status register - Added the code to follow the existing wait for SLIPort_Status register RDY, ERR, and RN bits to be set by the port before proceeding to perform PCI function reset. - Do not override ulpCt_h and ulpCt_l for SLI 4 ports. - For vport delete, call lpfc_nlp_put when the vport's vpi state is not marked with VPI_REGISTERED. - Added missed fields into the driver's Controller Attributes Structure - Changed ringing EQ/CQ/RQ doorbell register to be dependent on the size of the queue. - Return -EACCES in issue_reset if cfg_enable_hba_reset is zero. - Added new logging flag LOG_FCP_UNDER 0x00040000 to qualify underrun logging. - Add a check in the fabric name display routine to display 0 if the port state is <= FLOGI. - Add a check to the switch statement in lpfc_decode_firmware_rev to check for an 'X'.
