FYI, we got a small conflict when merging 'net' in 'net-next' in the
MPTCP tree due to this patch applied in 'net':

  99e4c35eada9 ("selftests: bonding: add ipsec offload test")

and this one from 'net-next':

  c2377f1763e9 ("selftests: bonding: add test for LACP actor port priority")

----- Generic Message -----
The best is to avoid conflicts between 'net' and 'net-next' trees but if
they cannot be avoided when preparing patches, a note about how to fix
them is much appreciated.

The conflict has been resolved on our side [1] and the resolution we
suggest is attached to this email. Please report any issues linked to
this conflict resolution as it might be used by others. If you worked on
the mentioned patches, don't hesitate to ACK this conflict resolution.
---------------------------

Regarding this conflict, I simply added the new files from both trees:

  bond_passive_lacp.sh \
  bond_ipsec_offload.sh \
  bond_lacp_prio.sh

Note: A way to reduce such conflicts in the future is to sort each entry
by alphabetical order instead of adding new ones at the end. Same in the
'config' file that is also modified in this patch.

Rerere cache is available in [2].
