2026-06-05selftests: drv-net: add userns devmem RX testBobby Eshleman
Add userns_devmem.py, which mirrors nk_devmem.py but places the netkit guest in a netns whose owning user_ns is non-init. ncdevmem is ran there via nsenter so the bind-rx call is issued with creds that hold CAP_NET_ADMIN only in the child user_ns. Without the preceding GENL_UNS_ADMIN_PERM patch the test fails at bind-rx with EPERM, but with the patch the transfer completes and tests pass.
