Subject: [PATCH net-next 0/1 v2] skbuff: Extend gso_type to unsigned int

We need a GSO type for IPsec ESP to be able to integrate the IPsec
hardware offloading infrastructure. Unfortunately, all gso_type flags
are currently in use. This change extends gso_type from 'unsigned short'
to 'unsigned int'.

Changes from v1:

- Place the remaining two byte hole in front, suggested by
  Eric Dumazet.

- Skipping the memset of the two byte hole is unnecessary
  as it does not matter if we memset two or four bytes more,
  suggested by Alexander Duyck.
