Subject: [PATCH bpf-next 0/5] bpf: Follow up on bpf __sk_buff->tstamp

This set is a follow up on the bpf side based on discussion [0].

Patch 1 is to remove some skbuff macros that are used in bpf filter.c

Patch 2 and 3 are to simplify the bpf insn rewrite on __sk_buff->tstamp.

Patch 4 is to simplify the bpf uapi by modeling the __sk_buff->tstamp
and __sk_buff->tstamp_type (was delivery_time_type) the same as its kernel
counter part skb->tstamp and skb->mono_delivery_time.

Patch 5 is to adjust the bpf selftests due to changes in patch 4.
