[PATCH AUTOSEL 4.14 2/3] tg3: Increment tx_dropped in tg3_tso_bug()

[Sasha Levin <sashal@kernel.org>]

From: Alex Pakhunov <alexey.pakhunov@spacex.com>

[ Upstream commit 17dd5efe5f36a96bd78012594fabe21efb01186b ]

tg3_tso_bug() drops a packet if it cannot be segmented for any reason.
The number of discarded frames should be incremented accordingly.
