Hi,
FYI, your patch has been queued to LTS release 16.11.9
Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 09/27/18. So please
shout if anyone has objections.
Also note that after the patch there's a diff of the upstream commit vs the patch applied
to the branch. If the code is different (ie: not only metadata diffs), due for example to
a change in context or macro names, please double check it.
Thanks.
Luca Boccassi

Subject: [PATCH] net/bonding: do not ignore RSS key on device config
[ upstream commit 83cf204a982918fd56b15f9d458d1dfb1e724b5f ]
Bonding driver ignores the value of RSS key (that is set in the port RSS
configuration) in bond_ethdev_configure(). So the only way to set
non-default RSS key is by using rss_hash_update(). This is not an
expected behaviour.
Make the bond_ethdev_configure() set default RSS key only if
requested key is set to NULL.
Fixes: 734ce47f71e0 ("bonding: support RSS dynamic configuration")
