Merge branch 'net-af_packet-be-careful-when-expanding-mac-header-size'
Eric Dumazet says:
net: af_packet: be careful when expanding mac header size
A recent regression in af_packet needed a preliminary debug patch,
which will presumably be useful for next bugs hunting.
The af_packet fix is to make sure MAC headers are contained in
skb linear part, as GSO stack requests.
v2: CONFIG_DEBUG_NET depends on CONFIG_NET to avoid compile
errors found by kernel bots.
