[PATCH net-next v2 0/7] AF_PACKET transport_offset fix

[Maxim Mikityanskiy <maximmi@mellanox.com>]

This patch series contains the implementation of the RFC that was posted
on this mailing list previously:
https://www.spinics.net/lists/netdev/msg541709.html

It fixes having incorrect skb->transport_header values in cases when
dissect fails. Having correct values set by the kernel fixes mlx5
operation and allows to remove some unnecessary code flows in mlx5.

v2 changes:

- Rebase against the fresh net-next.
- Don't return bool from skb_probe_transport_header (and don't rename
  the function).
- WARN_ON_ONCE and error path in case of GSO without the L4 header.

Maxim Mikityanskiy (7):
  net: Don't set transport offset to invalid value
  net: Introduce parse_protocol header_ops callback
  net/ethernet: Add parse_protocol header_ops support
  net/packet: Ask driver for protocol if not provided by user
  net/packet: Remove redundant skb->protocol set
  net/mlx5e: Remove the wrong assumption about transport offset
  net/mlx5e: Trust kernel regarding transport offset
