Subject: [PATCH net 0/2] net: gro: fix outer network offset

The GRO stage has still problems in some edge scenarios when dealing
with encapsulated traffic: the first patch address an issue there
leading to bad checksums.

The second patch introduces a test case covering the relevant scenario:
S/W segmentation after GRO for encapsulated traffic.

Paolo Abeni (2):
  net: gro: fix outer network offset
  selftest: net: add a test-case for encap segmentation after GRO
