Subject: scsi: lpfc: Introduce LOG_NODE_VERBOSE messaging flag
Patch-mainline: v6.7-rc1
Git-commit: 41c831bbb0f277ecadbcc79f61a42d3a6bbe0dc4
References: bsc#1217124
The preexisting LOG_NODE message flag frequently spams a subset of the same
log messages during normal FC driver operations. When analyzing driver
logs, this sometimes leads to difficulty in troubleshooting.
Because LOG_IP log message flag is unused, convert it to a new
LOG_NODE_VERBOSE flag. The LOG_NODE_VERBOSE shall specifically be used for
diagnosing issues that require precise ndlp tracking detail.
