Subject: [RFC PATCH bpf-next v4 0/2] Replace mono_delivery_time with tstamp_type
Date: Wed, 17 Apr 2024 17:43:06 -0700 [thread overview]
Message-ID: <20240418004308.1009262-1-quic_abchauha@quicinc.com> (raw)
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 also
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 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.
