Add a selftest for netdev generic netlink. For now there is only a
single test that exercises the `queue-get` API.
The test works with netdevsim by default or with a real device by
setting NETIF.
Add a timeout param to cmd() since ethtool -L can take a long time on
real devices.

Add a very simple test for testing with a remote system.
Both IPv4 and IPv6 connectivity is optional, later change
will add checks to skip tests based on available addresses.
Using netdevsim:
$ ./run_kselftest.sh -t drivers/net:ping.py
TAP version 13
1..1
# timeout set to 45
# selftests: drivers/net: ping.py
# KTAP version 1
# 1..2
# ok 1 ping.test_v4
# ok 2 ping.test_v6
# # Totals: pass:2 fail:0 xfail:0 xpass:0 skip:0 error:0
ok 1 selftests: drivers/net: ping.py
Command line SSH:
$ NETIF=virbr0 REMOTE_TYPE=ssh REMOTE_ARGS=root@192.168.122.123 \
LOCAL_V4=192.168.122.1 REMOTE_V4=192.168.122.123 \
./tools/testing/selftests/drivers/net/ping.py
KTAP version 1
1..2
ok 1 ping.test_v4
ok 2 ping.test_v6 # SKIP Test requires IPv6 connectivity
# Totals: pass:1 fail:0 xfail:1 xpass:0 skip:0 error:0
Existing devices placed in netns (and using net.config):
$ cat drivers/net/net.config
NETIF=veth0
REMOTE_TYPE=netns
REMOTE_ARGS=red
LOCAL_V4="192.168.1.1"
REMOTE_V4="192.168.1.2"
$ ./run_kselftest.sh -t drivers/net:ping.py
TAP version 13
1..1
# timeout set to 45
# selftests: drivers/net: ping.py
# KTAP version 1
# 1..2
# ok 1 ping.test_v4
# ok 2 ping.test_v6 # SKIP Test requires IPv6 connectivity
# # Totals: pass:1 fail:0 xfail:1 xpass:0 skip:0 error:0

Add drivers/net as a target for mixed-use tests.
The setup is expected to work similarly to the forwarding tests.
Since we only need one interface (unlike forwarding tests)
read the target device name from NETIF. If not present we'll
try to run the test against netdevsim.
