Note that the bug seems reproducible 100% by changing link state, by
either rebooting the switch or disconnect/reconnect the Eth cable.

It's hitting an ASSERT_RTNL in netif_set_real_num_tx_queues(), looks
like igb_runtime_resume() thinks it doesn't need RTNL, as rpm == true in
the call to __igb_resume() from igb_runtime_resume(). I'm not sure why
it's written that way since the call to set the queues is unconditional
in __igb_open
