One from myself for a change; two LORs and a firmware crash (PHY_CONTEXT_CMD)

Got started by

I believe I fixed that with an update to https://reviews.freebsd.org/D49761
So if yu are trying that patch and see this, please update the patch
again. You can drop the old one using git and then apply the new
version using arc again for example.
