Subject: [PATCH v2 net 0/3] net: af_packet: be careful when expanding mac header size

From: Eric Dumazet <edumazet@...gle.com>

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.

Eric Dumazet (3):
  net: CONFIG_DEBUG_NET depends on CONFIG_NET
  net: add debug info to __skb_pull()
  net/af_packet: make sure to pull mac header
