Subject: [PATCH v4 12/13] scsi: fnic: Improve logs and add support for multiqueue (MQ)
Improve existing logs by adding fnic number, hardware queue,
tag, and mqtag in the prints.
Add logs with the above elements for effective debugging.
Changes between v2 and v3:
Incorporate the following review comment from Hannes:
Use fnic_num as an argument to FNIC_SCSI_DBG.
Modify definition of FNIC_SCSI_DBG.
Host number is still an argument since
FNIC_SCSI_DBG in turn uses shost_printk.
