Subject: [PATCH] mac80211: minstrel_ht: fix sample time check
|
|
|
|
We need to skip sampling if the next sample time is after jiffies, not before.
|
|
This patch fixes an issue where in some cases only very little sampling (or none
|
|
at all) is performed, leading to really bad data rates
|
|
|
|
Fixes: 80d55154b2f8 ("mac80211: minstrel_ht: significantly redesign the rate probing strategy")
