Note that rss_ctx.test_rss_context_out_of_order fails with the device
I tested with, but it seems to be a device / driver bug.

selftests: drv-net: add ability to wait for at least N packets to load gen
Teach the load generator how to wait for at least given number
of packets to be received. This will be useful for filtering
where we'll want to send a non-trivial number of packets and
make sure they landed in right queues.

While we are not very interested in testing performance
it's useful to be able to generate a lot of traffic.
iperf is the simplest way of getting relatively high PPS.

selftests: drv-net: add a TCP ping test case (and useful helpers)
More complex tests often have to spawn a background process,
like a server which will respond to requests or tcpdump.
Add support for creating such processes using the with keyword:
with bkg("my-daemon", ..):
# my-daemon is alive in this block
My initial thought was to add this support to cmd() directly
but it runs the command in the constructor, so by the time
we __enter__ it's too late to make sure we used "background=True".
Second useful helper transplanted from net_helper.sh is
wait_port_listen().
The test itself uses socat, which insists on v6 addresses
being wrapped in [], it's not the only command which requires
this format, so add the wrapped address to env. The hope
is to save test code from checking if address is v6.
