selftests/net: psp: support PSP in NetDrvContEnv infrastructure
Add infrastructure to support PSP tests across network namespaces
using NetDrvContEnv with netkit pairs. This enables testing PSP device
association, where a non-PSP-capable device (e.g. netkit) in a guest
namespace is associated with a real PSP device in the host namespace,
allowing the guest to perform PSP encryption/decryption through the
host's PSP hardware.
The topology is:
Host NS: psp_dev_local <---> nk_host
| |
| | (netkit pair)
| |
Remote NS: psp_dev_peer Guest NS: nk_guest
(responder) (PSP tests)
env.py:
- nk_guest_ifindex is queried after moving the device into the guest
namespace, so tests can use it directly for dev-assoc
psp.py:
- PSP device lookup supports container environments where the PSP
device is on the physical interface, not the test interface
- Association helpers handle dev-assoc/dev-disassoc with defer-based
cleanup to prevent state leaks on test assertion failures
- main() tries NetDrvContEnv with primary_rx_redirect and falls back
to NetDrvEpEnv, so existing tests continue to work without the
container environment

Rename _nk_host_ifname to nk_host_ifname in NetDrvContEnv to make it
a public attribute, matching the nk_guest_ifname rename. Tests that
access the host-side netkit interface name (e.g. for cleanup after
deleting the netkit pair) no longer trigger pylint protected-access
warnings.

selftests: drv-net: add primary_rx_redirect support to NetDrvContEnv
When sending from a namespace that has access to a netkit device with a
leased queue, the nk primary in the host namespace needs to redirect its
RX to the physical device. This patch adds that redirection bpf program
and teaches the harness to install it.
Add primary_rx_redirect=False parameter to NetDrvContEnv.__init__().
When enabled, _attach_primary_rx_redirect_bpf() attaches a new BPF TC
program (nk_primary_rx_redirect.bpf.c) to the primary (host-side) netkit
interface. The program redirects non-ICMPv6 IPv6 packets to the physical
NIC via bpf_redirect_neigh(), with the physical ifindex configured via
the .bss map. ICMPv6 is left on the host's netkit primary so IPv6
neighbor discovery still work locally.
Extract _find_bss_map_id() from _attach_bpf() into a reusable helper so
other BPF attachment methods can use it.

selftests/net: Add env for container based tests
Add an env NetDrvContEnv for container based selftests. This automates
the setup of a netns, netkit pair with one inside the netns, and a BPF
program that forwards skbs from the NETIF host inside the container.
Currently only netkit is used, but other virtual netdevs e.g. veth can
be used too.
Expect netkit container datapath selftests to have a publicly routable
IP prefix to assign to netkit in a container, such that packets will
land on eth0. The BPF skb forward program will then forward such packets
from the host netns to the container netns.

selftests/net: Make NetDrvContEnv support queue leasing
Add a new parameter `lease` to NetDrvContEnv that sets up queue leasing

The NETIF also has some ethtool parameters changed to support memory
provider tests. This is needed in NetDrvContEnv rather than individual
test cases since the cleanup to restore NETIF can't be done, until the
netns in the env is gone.
