Subject: ofproto: Make current packet counts more accurate.
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=b3137fe852171f8e87a49ef0939a52d91ea09720;p=openvswitch

ofproto: Make current packet counts more accurate.

When the stats for a currently active flow are requested this
ensures that the packets not handled by the kernel are counted
immediately.  Before, these packets would only be counted once
the kernel flow expired and the counts were combined.
