From 69f132236827ce7d4531846cc2b9447dd5620aff Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Fri, 26 Jun 2015 09:21:01 +0200 Subject: [PATCH] mac80211: shrink struct ieee80211_fragment_entry Most of the fields in this struct use too wide types, change that to shrink the struct from 64 to 48 bytes (on 64-bit.) This results in a total saving of 64 bytes for each interface.
