5.15-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.
Fixes: 188f4af04618 ("r8169: use NETDEV_TX_{BUSY/OK}")
