NOTE: the following applies after previous Performance Manager patches posted
to the list.
The initial performance manager only logged Symbol Error, Receive errors, and
xmit discards. Additional errors from PortCounters should be logged.
- Change error codes to use 4C3X, allows future expansion
- Add perfmgr_log_errors flag (default true), allows users to reduce log
spamming if they are using an alternate method to collect perfmgr data.
Changes since V1:
Add help message within generated opensm.conf
