Bug#841028: Same behaviour but triggered when two network cards present

[Szymon Krupinski <szymk1@gmail.com>]

Dear Debian/Cups Team,

My cups installation gives the same symptoms (cups-daemon 2.2.8-5,
amd64, kernel 4.17.0-3-amd64). Yet, it only does so when two network
cards are present. To be precise: I have a wireless card which
connects to university network (with plenty of online printers) and a
docking station which is equipped with an Ethernet card also connected
to the LAN. The 100% CPU usage is only triggered when I put my laptop
in the docking station. It does not happen in my home Wifi network.

Hope it sheds more light on the problem.

Regards,

Szymon
