Patch 2 :- Additional bit was added to support tai timestamp type to avoid tstamp drops in the forwarding path when testing TC-ETF. With this patch i am updating bpf filter.c and not sure what impacts it has towards BPF code. I need upstream BPF community to help me in adding the necessary BPF changes to avoid any BPF test case failures. I have added some BPF changes as part of this commit to handle cases of both tai and mono bit being set at the same time.
