Subject: Troubleshooting mwl8k driver issue
Date: Fri, 3 Jun 2016 22:54:52 -0500 [thread overview]
Message-ID: <20160604035452.GA5925@dar.local> (raw)
Lennert, I am a user of your mwl8k driver through the OpenWRT
distribution. When working with certain WiFi devices I get errors in
the kernel logs and network connectivity errors on the wireless device.
The dmesg logs look like this:
[539374.394607] ieee80211 phy1: Added a new stream for (BSSID MAC) 0
[539374.394650] ieee80211 phy1: Started stream for (BSSID MAC) 0
[539374.394732] ieee80211 phy1: tx rings drained
[539374.401372] ieee80211 phy1: Created a BA stream for (BSSID MAC) : tid 0
`iw event -t' logs (it looks like OpenWRT is patching the heck out of this
tool):
1465008930.594531: wlan1 (phy #1): unknown event 60
1465008930.652119: wlan1 (phy #1): unknown event 60
1465008930.653494: wlan1 (phy #1): unknown event 60
1465008930.655582: wlan1: new station (BSSID MAC)
There are a number of other users who are also experiencing the same
issue on the OpenWRT bug tracker:
https://dev.openwrt.org/ticket/21284
As I noted in the bug the driver works with some of my wireless devices
and not others which suggests that something subtle is up with some
driver in this picture.
I don't have a whole lot of experience with kernel development (pretty
much none actually) and I know absolutely nothing about how these WiFi
devices work. However I am willing to work with you or anyone else on
the linux-wireless list (which I have CCd) to help troubleshoot this
issue. I am using OpenWRT on this router and I can get a build
environment set up for debug kernel builds with their toolchain. I'm
running a pretty recent kernel (4.4.7) but git log suggests this driver
hasn't been touched in a while.
