OK, the patch itself is correct.

Now, could you please send it again with a proper changelog ?

In this changelog, please explain why patch is needed, and
keep lines short (< 72 chars), like the one you did in your first mail.

I'll then add my Signed-off-by, since I wrote the accelerated part ;)

Note : I wonder if another patch is needed, in case 8021q module is
_not_ loaded. We probably should accept vlan 0 frames in this case ?
