[PATCH 3.16 149/294] r8169: Be drop monitor friendly

From: Ben Hutchings
Date: Mon Nov 06 2017 - 18:55:16 EST


3.16.50-rc1 review patch. If anyone has any objections, please let me know.

------------------

From: Florian Fainelli <f.fainelli@xxxxxxxxx>

commit 7a4b813cb739ce598ffbad2e84d19d13fa23e25d upstream.

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")
