As fixes for Networking code these should have fixes tags.
I think the following are appropriate.

Fixes: 7a82ecf4cfb8 ("net/ncsi: NCSI AEN packet handler")
Fixes: 138635cc27c9 ("net/ncsi: NCSI response packet handler")

As they seem to be commits from the same patch-set,
included in the same release - v4.8-rc1, I think
we can keep this as a single patch.

If you agree then it shouldn't be necessary to post a new version because
of this, as patchwork should pick up the tags above. But for future
reference, assuming these are backporting candidates, it's best to CC
stable on bugfixes for net.

Overall, this looks good to me.
