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") Cc: stable@vger.kernel.org Signed-off-by: Felix Fietkau <nbd@nbd.name> Link: https://lore.kernel.org/r/20210617103854.61875-1-nbd@nbd.name Signed-off-by: Johannes Berg <johannes.berg@intel.com>
