Thanks for the update. I'm adding e1000-devel so we can track this for
Intel support.

We are looking into the issues you have reported. Please just add
these to the Bugzilla you already have open on the issue. No need to
start new threads on netdev.

It will likely take a while for us to resolve the issues you have seen
on 4.14 since we will need to work with our firmware team to
understand where the filtering resources are going.
