[ovs-dev] [PATCH] Update subfacet stats for slow path flow

[gyang at nicira.com]

From: Guolin Yang <gyang at nicira.com>

The slow path stats are not updated which cause slow path flow to be
deleted periodically. This patch update the slow path flow as fast
path flow so that the flow will not be aged out.

Another option is update the subfacet for slow path when packet is received
and that is original code but it is removed.

One note is with this change, one of ofproto-dpif test fail, probably should
update the test case also.
