[PATCH 5.10 246/352] r8169: dont increment tx_dropped in case of NETDEV_TX_BUSY

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



5.10-stable review patch.  If anyone has any objections, please let me know.

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

From: Heiner Kallweit <hkallweit1@xxxxxxxxx>

commit d516b187a9cc2e842030dd005be2735db3e8f395 upstream.

The skb isn't consumed in case of NETDEV_TX_BUSY, therefore don't
increment the tx_dropped counter.
