Subject[PATCH 2/3] net: openvswitch: use core API for updating TX stats
Date
Commit d3fd65484c781 ("net: core: add dev_sw_netstats_tx_add") has added
function "dev_sw_netstats_tx_add()" to update net device per-cpu TX
stats.

Use this function instead of own code. While on it, replace
"len" variable with "skb->len".
