From 71b7987ec001a60dff689e56f4b041cfc4222c6b Mon Sep 17 00:00:00 2001 From: Sven Eckelmann Date: Wed, 10 Jun 2026 23:16:18 +0200 Subject: [PATCH] batman-adv: tp_meter: simplify unordered ack calculation When batadv_tp_ack_unordered() goes through the list of unacked sequence numbers and checks for now closed gaps, it is first calculating a delta of the sequence numbers which could be acked. Just to revert this calculation in the next steps to the sequence number which would be ackable. Skip the delta step and directly work with the sequence numbers.
