From 67dfdbd8f9bad173c874d61aefd43cceadeae259 Mon Sep 17 00:00:00 2001 From: David Gibson Date: Tue, 18 Aug 2026 14:35:13 +1000 Subject: udp_flow: Remove obsolete comment This comment was true - although the upshot was not particularly clear - when it was introduced. However, for other reaosns we now *do* always populate ini->oaddr from flow_initiate_sa(). So rather than explaning why we can't, we can actually validate ini->oaddr.
