I built new kernel with "options RSS" however TCP throughput performance
now decreased from 128 MiB/sec to 106 MiB/sec.
Looks like the problem has shifted from epair to netisr

Tried both, kernel built with "options RSS" and the following
in /boot/loader.conf
net.isr.maxthreads=-1
net.isr.bindthreads=1
net.isr.dispatch=deferred
Not sure if there are race conditions with these implementations, but
after a few short tests, the epair_task_0 got stuck 100% on CPU and
stayed

Thank you for the response and for sharing your scenario.
We’ve also hacked up the cgem and the ffec driver to support a shared mdio.
That was not too difficult, but we have a new scenario where the mdio is now
being shared between two different devices that use different drivers (ffec and
eqos)

@Mithun
It seems this has been fixed by Kristof via commit 43387b4e5740 (if: guard
against if_ioctl being NULL). The commit has been MFCed to stable/14 with
commit 9a8a26aefb36.
