Then please use netdev_alloc_skb_ip_align(), so that you get rid of
skb_reserve()

It seems there are ~50 of these in the kernel tree
that could be converted.

Make sure the 2 is really NET_IP_ALIGN

Some hardwares need 2, even if NET_IP_ALIGN is 0 (on x86 arches for
example)

Even on x86 aligning the ethernet receive data on a 4n+2
boundary is likely to give marginally better performance
than aligning on a 4n boundary.
