This is a note to let you know that I've just added the patch titled net: xscale: Fix return type for implementation of ndo_start_xmit to the 6.0-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: net-xscale-fix-return-type-for-implementation-of-ndo.patch and it can be found in the queue-6.0 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 7a6ce87e72ba0df668f59ab337670f25ec1ecd90 Author: GUO Zihua <guozihua@xxxxxxxxxx> Date: Fri Sep 2 16:16:12 2022 +0800 net: xscale: Fix return type for implementation of ndo_start_xmit [ Upstream commit 0dbaf0fa62329d9fe452d9041a707a33f6274f1f ] Since Linux now supports CFI, it will be a good idea to fix mismatched return type for implementation of hooks. Otherwise this might get cought out by CFI and cause a panic. eth_xmit() would return either NETDEV_TX_BUSY or NETDEV_TX_OK, so change the return type to netdev_tx_t directly.
