Patch 2 :- Starts assigning tstamp_type with either mono or real and introduces a new enum in the skbuff.h, again no change in functionality of the existing available code in kernel , just making the code scalable Patch 3 :- Additional bit was added to support userspace timestamp to avoid tstamp drops in the forwarding path when testing TC-ETF. With this patch i am 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 haven't changed any of the BPF functionalities and hence i need upstream BPF help to assist me with those changes so i can make them as part of this patch.
