[SCSI] lpfc 8.2.6 : Miscellaneous Fixes
Miscellaneous Fixes - Allow WRITE_VPARAM command when the virtual port is in a stopped state - Fixed handling of our queue depth max that was unconditionally raising the depth on all vports, rather than just the vport affected. - Fix race in interrupt handler for mailbox processing that did not take out the host lock. - Removed unused functions: find_node, findnode_rpi, and fabric_abort_flogi - Correct misspelled word unsolicited in message 0146 - Correct HW-error 5 handling - it should not reset the adapter - Correct handling of IOCBs, which did not null out our pCmd field before invoking the midlayer io done function. - Changed our maximum supported target id to 4096 Signed-off-by: James Smart <james.smart@emulex.com> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>
