Since 0417adf367a0 ("ppp: fix race conditions in ppp_fill_forward_path")
dev_fill_forward_path() should be called with RCU read lock held. This
fix was applied to net, while the Airoha flowtable commit was applied to
net-next, so it hadn't been an issue until net was merged into net-next.

Fixes: a9af709fda7e ("Merge git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net")

I understand from the patch description that the problem didn't manifest
until this merge commit. But nonetheless I don't think using
a merge commit in the Fixes tag is the best approach. For one thing,
it seems somewhat difficult to use effectively to guide backporting.

I would suggest using the flowtable commit as the fixes tag:

Fixes: a8bdd935d1dd ("net: airoha: Add wlan flowtable TX offload")

Or perhaps fixes tags for both a8bdd935d1dd and 0417adf367a0.

Flagged by AI generated code review, which also suggested citing a8bdd935d1dd.
