[PATCH net] selftests: drv-net: add missing tc config options for netkit tests

[PATCH net] selftests: drv-net: add missing tc config options for netkit tests

[Bobby Eshleman]

From: Bobby Eshleman <bobbyeshleman@meta.com>

The NetDrvContEnv env context uses tc clsact qdiscs and BPF tc filters
for traffic redirection, but the kernel config options are missing from
the selftests config.

Without them, the tc qdisc installation trips on:

  CMD: tc qdisc add dev enp1s0 clsact
    EXIT: 2
    STDERR: Error: Specified qdisc kind is unknown.

  net.lib.py.utils.CmdExitFailure: Command failed

Add CONFIG_NET_CLS_ACT and CONFIG_NET_SCH_INGRESS to enable these tc
options.

Fixes: 3f74d5bb807e ("selftests/net: Add env for container based tests")

Hi Bobby,

Unfortunately this does not apply cleanly to net.
Which breaks CI.

Please rebase and repost.

Oh, I see now that 3f74d5bb807e ("selftests/net: Add env for container
based tests") is only in net-next, not net yet.

I'll resend with the proper tag.

Best,
Bobby
