[RFC,bpf-next,v1,0/3] Rename mono_delivery_time to

Message

Abhishek Chauhan (ABC) April 9, 2024, 9:05 p.m. UTC

Patch 1 :- This patch takes care of only renaming the mono delivery
timestamp to tstamp_type with no change in functionality of 
existing available code in kernel. 

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.    


Abhishek Chauhan (3):
  net: Rename mono_delivery_time to tstamp_type for scalibilty
  net: assign enum to skb->tstamp_type to distinguish between tstamp
  net: Add additional bit to support userspace timestamp type
