You should also prefix your patches with "net: stmmac" to be consistent. Finally, since these are fixes, please indicate clearly which networking tree you are targeting: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/Documentation/networking/netdev-FAQ.rst#n28 Thanks

If clear GMAC_CONFIG_TE bit, it would stop all tx channals, but users may only want to stop secific tx channel.
