Subject: [PATCH 4.14 159/496] r8152: fix tx packets accounting
4.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: Eric Dumazet <edumazet@...gle.com>
[ Upstream commit 4c27bf3c5b7434ccb9ab962301da661c26b467a4 ]
r8152 driver handles TSO packets (limited to ~16KB) quite well,
but pretends each TSO logical packet is a single packet on the wire.
There is also some error since headers are accounted once, but
error rate is small enough that we do not care.
