Merge branch 'AF_PACKET-transport_offset-fix'
Maxim Mikityanskiy says:
====================
AF_PACKET transport_offset fix
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.
====================
