Subject: Merge "sflow" into "master".
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=49c36903d6d65bed96cba31f05534510a21a68d7;p=openvswitch

Merge "sflow" into "master".

No conflicts, but lib/dpif.c needed a few changes since struct dpif's
member "class" was renamed to "dpif_class" in master since sflow was
branched off.
