Subject: [PATCH] net: korina: remove busy skb free
Date: Sun, 13 Dec 2020 18:20:52 +0100	[thread overview]
Message-ID: <20201213172052.12433-1-vincent.stehle@laposte.net> (raw)

The ndo_start_xmit() method must not attempt to free the skb to transmit
when returning NETDEV_TX_BUSY. Fix the korina_send_packet() function
accordingly.

Fixes: ef11291bcd5f ("Add support the Korina (IDT RC32434) Ethernet MAC")
