Subject: meta-flow: Update mf_field description of size.
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=9df6a67988a32ad65e5b358f460bacf9b4cf34a2;p=openvswitch

meta-flow: Update mf_field description of size.

Commit 7257b5 (Implement new fragment handling policy.) added a new
"is_frag" meta-field that used fewer bits than the width of the field.
A comment in mf_field lists these cases, but "is_frag" wasn't included.
This commit updates that.
