Details

Summary

The Ethernet PCP codepoint should be configurable
for L2 local traffic, to allow lower latency for
iSCSI block IO. This Diff addresses the initiator
side only.

Test Plan

Once a PCP is configured to a target, validate
with tcpdump, that a 802.1Q header is injected
containing the appropriate PCP value.

Thanks for implementing that feature.
There is a minor mandoc issue, easy to fix. Running "mandoc -Tlint" and textproc/igor will usually tell you about them.

You need to make a line break after the sentence stop here.
