From 928dc406802dc4547b5ef84c3075fe144d4cbcf1 Mon Sep 17 00:00:00 2001 From: Cong Wang Date: Fri, 2 Apr 2021 22:27:15 -0700 Subject: bpf, udp: Remove some pointless comments These comments in udp_bpf_update_proto() are copied from the original TCP code and apparently do not apply to UDP. Just remove them.
