Subject: [PATCH net-next v2 00/11] MCTP core protocol updates, minor fixes & tests

This series implements some procotol improvements for AF_MCTP,
particularly for systems with multiple MCTP networks defined. For those,
we need to add the network ID to the tag lookups, which then suggests an
updated version of the tag allocate / drop ioctl to allow the net ID to
be specified there too.

The ioctl change affects uabi, so might warrant some extra attention.

There are also a couple of new kunit tests for multiple-net
configurations.

We have a fix for populating the flow data when fragmenting, and a
testcase for that too.

Of course, any queries/comments/etc., please let me know!

Cheers,


Jeremy

v2:
 - [06/11] fix forwards-compat check on local_peer, based on feedback
   from Dan Carpenter <dan.carpenter@...aro.org>
 - [10/11] don't skip the flow tests for a kunit all-tests run, based on
   feedback from Jakub Kicinski <kuba@...nel.org>
