Oh hai!

I've created bugzilla ticket about this, but I'm not sure if anyone
reads it, so duplicating here.

I have new motherboard (ASUS A320-K) with 10ec:8168 realtek network
card installed and it doesn't work (i. e. `tcpdump` shows outgoing
packets but no packets are actually transmitted and `tcpdump` doesn't
show incoming packets while they are trasmitted from the other side)
then after 200-300 seconds I see [full stacktrace [1] and lspci [2]
output are attached to bugzilla ticket]

and everything starts working normally. How can I make it work right after boot?

The issue is reproducible in linux-4.16.5 & linux-4.17-rc2 with
rtl_nic fw from linux-firmware git master.
