Add network QoS support for PCP to iscsi initiator.

Authored by rscheff on Oct 11 2020, 1:24 PM.



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.
