[PATCH net-next 0/4] selftests/net: add netkit container env and test

[David Wei <dw@davidwei.uk>]

Add a new Python selftest env NetDrvContEnv that sets up a pair of
netkit netdevs, with one inside of a netns, and a bpf prog that forwards
skbs from NETIF to the netkit inside the netns.

    +-------------+        +----------------------------+
    | INIT NS     |        | TEST NS                    |
    | +---------+ |        | +------------------------+ |
    | | NETIF   | |  bpf   | | Netkit                 | |
    | |         |-|--------|>| nk_guest               | |
    | +---------+ |        | | {LOCAL_PREFIX_V6}::2:2 | |
    | +---------+ |        | +------------------------+ |
    | | Netkit  | |        +----------------------------+
    | | nk_host | |
    | +---------+ |
    +-------------+

I will use this series for queue leasing selftests. Include a basic ping
test in this series as demonstration.
