Just noticed that this only went to net-next (and 5.4-rc1), when actually
it's needed on all kernels back to 4.19 (per the first Fixes: tag). The
second Fixes: reference, 323ebb61e32b, merely enables syzbot to hit it on
whatever hardware it has, but the bug was already there, and hittable on
sfc NICs.
David, can this go to stable please?
