Hey Abhishek, Thanks for the patch! This is a new feature for netdev, so the Subject should have "net-next" in it: https://docs.kernel.org/process/maintainer-netdev.html#tl-dr Another thing, the kernel is very particular about the commit messages. I thought checkpatch.pl would complain about the subject line, but surprisingly it didn't. Usually going with a "when in rome" approach is good (i.e. take a look at the git log). So here something like: "net: stmmac: dwmac-qcom-ethqos: Enable TBS on all queues but 0" would be better. Its a short one line subject, that has the appropriate prefix, etc. You could then embed the information about TSO and TBS being exclusive, and maybe explain your reasoning on why this allocation of queues (TSO on 0, TBS on the rest) was done.. etc in the body. Maybe even pointing to the similar NXP related patch Esben posted recently would be smart since your motivation is the same: commit 3b12ec8f618ebaccfe43ea4621a6f5fb586edef8 Author: Esben Haabendal <esben@xxxxxxxxxx> Date: Fri Jan 26 10:10:42 2024 +0100 net: stmmac: dwmac-imx: set TSO/TBS TX queues default settings TSO and TBS cannot coexist. For now we set i.MX Ethernet QOS controller to use the first TX queue with TSO and the rest for TBS. TX queues with TBS can support etf qdisc hw offload.

This allows using the etf qdisc with hw offload on the TBS enabled queues.
