jacob.e.keller_intel.com accepted D25954: Remove redeclaration found by gcc build.

This looks correct to me. One of the folks actively working on the Intel networking drivers should take a look to make sure they're aware of it.

jacob.e.keller_intel.com abandoned D22214: factor out remove logic from if_delgroup and if_delgroups.

It looks like similar work was done via r355942, with slightly different (better) function names, and various style changes. This can be closed as essentially resolved/committed now.

jacob.e.keller_intel.com added a comment to D22870: ixl: prevent non-privileged access to NVM update interface.

I mean ixl_if_priv_ioctl(). I'm not sure what you mean by "that" ioctl, since ixl_if_priv_ioctl() handles multiple ioctls by virtue of not looking at the command argument. In particular, iflib passes driver-specific ioctls to ixl_if_priv_ioctl() and so would not seem to be the right place to check for privileges for exactly the reason that you state.

Thanks for fixing this. The NULL canaries were left over from when iflib had a separate code path which avoided busdma. When I removed this codepath, I neglected to remove those canaries.

The fact that the map pointer can be NULL is weird, but we found this to be true in several places, and without the removal of the NULL checks we end up leaking ~200 bytes of M_DEVBUF, and associated other DMA memory allocated outside of malloc.

Updated the review to add vlan event handler unregister calls before iflib_stop as well. I kept the call in iflib_deregister as well so that they get cleaned up properly during error flows. Now it uses the "unregister -> assign NULL" pattern so that only one of the flows will actually perform an unregister check.
