From 70550df2d354f13ae0544f12aa14b79f094f0de2 Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Wed, 14 Dec 2016 20:46:56 +0100 Subject: [PATCH] mac80211: minstrel_ht: make att_hist and succ_hist u32 instead of u64 They are only used for debugging purposes and take a very long time to overflow. Visibly reduces the size of the per-sta rate control data.
