[PATCH net-next v5 2/2] net-timestamp: add selftests for SOF_TIMESTAMPING_OPT_RX_FILTER

[Jason Xing <kerneljasonxing@gmail.com>]

From: Jason Xing <kernelxing@tencent.com>

Test a few possible cases where we use SOF_TIMESTAMPING_OPT_RX_FILTER
with software or hardware report/generation flag.

Signed-off-by: Jason Xing <kernelxing@tencent.com>

1. add a new combination test when both flags are set at once
