[ovs-dev] [PATCH net-next v5 0/2] MPLS: Add limited GSO support

[Simon Horman]

In the case where a non-MPLS packet is received and an MPLS stack is
added it may well be the case that the original skb is GSO but the
NIC used for transmit does not support GSO of MPLS packets.

The aim of this short series is to provide GSO in software for MPLS packets
whose skbs are GSO.

Change since v4:

Update first patch of the series to use 16 bits for all *_headers
rather than just inner_*_headers

Simon Horman (2):
  net: Use 16bits for *_headers fields of struct skbuff
