Subject: [PATCH net 2/2] r8169: Be drop monitor friendly
Date: Thu, 24 Aug 2017 18:34:44 -0700	[thread overview]
Message-ID: <20170825013444.27326-3-f.fainelli@gmail.com> (raw)
In-Reply-To: <20170825013444.27326-1-f.fainelli@gmail.com>

rtl_tx() is the TX reclamation process whereas rtl8169_tx_clear_range() does
the TX ring cleaning during shutdown, both of these functions should call
dev_consume_skb_any() to be drop monitor friendly.

Fixes: cac4b22f3d6a ("r8169: do not account fragments as packets")
Fixes: eb781397904e ("r8169: Do not use dev_kfree_skb in xmit path")
