![James Smart](/assets/img/avatar_default.png)
Miscellaneous Fixes: - Fix bug in mbox sysfs interface that locked in EAGAIN if discovery stalled. - Fix missing error message when npiv and loop are true when link up occurs. - Fix panic in lpfc_scsi_cmd_iocb_cmpl: scsi_buf was NULL, but created race conditions with other code paths. - Fix error in sysfs mailbox structure that didn't rezero on next use. - Add missing mempool_free() to attachment failure path - Fix missing put of ndlp structure during driver unload. - Fix applications unable to send mailbox commands during discovery. - Remove unused argument (type) from function lpfc_post_buffer() API - Fix vport name is not shown after hbacmd vportcreate. - Remove repeated code statements.
