[ovs-dev] [PATCH v2] dpif-netdev: Reset the rxq current cycle counter on reload.

[Kevin Traynor]

An rxq may have processing cycles counted in the current
counter when a reload happens. That could temporarily create
a small skew on the stats for an rxq. Reset the counter after
reload.

V2:
- No change, just split from series as is a minor fix
  and no longer causes rebase issues.
