Re: [PATCH net-next 4/5] selftests: net: terminate bkg() commands on exception

There is a number of:

with bkg("socat ..LISTEN..", exit_wait=True)

uses in the tests. If whatever is supposed to send the traffic fails we will get stuck in the bkg(). Try to kill the process in case of exception, to avoid the long wait.

A specific example where this happens is the devmem Tx tests.
