Zeeb --- This is not a race condition in LinuxKPI; this is net80211 creating/using a new ni (sta) for a next packet without tearing down the previous sta proper= ly or letting us setup the new one. iwlwifi seems to be able to deal with this at the current stage but rtw8x a= nd mt76 go kaboom. I believe there's at least another two PRs open related to this (or maybe i= t's just in my head as I've seen it) and the release notes for 15.1 indicate problems with certain rtw8x chipsets. I can think of a possible work around in LinuxKPI 802.11 but after all the years I got tired of implementing workarounds and the real fix is to get net80211 right now but that does not happen over night. --=20 You are receiving this mail because: You are the assignee for the bug.=
