Stanislaw et al,
Thanks for working on this, I have a small stack of different devices
covered by this driver which I'm excited to test with.
I'm running wireless-testing which may or may not be fully up to date
on the patches you have sent (head is at
c9cd161770dd1866207b70d41ec03c9a26eea94f from Aug 13th), so please
tell me if this has already been fixed. I have a script that attempts
to connect to 16 differently configured SSIDs using 33 different (yet
compatible) wpa_supplicant.conf files and reports failures to me.
It's hardly perfect, but it gives me an idea if something is obviously
broken and needs a deeper dive. When I run this script against a
device supported by mt76x2 or mt76x0 I get an unusual error.
Everything goes fine, connect, dhcp, disconnect, connect, dhcp,
disconnect, but after about 5 or 6 connections I start getting errors
like this during wpa_supplicant:
Could not set interface t2uh flags (UP): No space left on device
nl80211: Could not set interface 't2uh' UP
nl80211: deinit ifname=t2uh disabled_11b_rates=0
t2uh: Failed to initialize driver interface
and then this with dhcpcd:
dhcpcd_prestartinterface: t2uh: No space left on device
t2uh: waiting for carrier
the same happens with just ifconfig up:
SIOCSIFFLAGS: No space left on device
I see nothing useful in dmesg, and this happens after multiple
successful connections. I've used this test setup before, and never
seen anything like this. I will be happy to provide more detail if
requested, but for now here is a list of the tested device which
exhibit this behavior (named for my convenience to the model):
phy1 036acm mt76x2u MediaTek Inc.
phy0 pau0a mt76x0 MediaTek Inc.
phy2 t1u mt76x0
phy3 t2u mt76x0 Ralink Technology, Corp.
MT7610U ("Archer T2U" 2.4G+5G WLAN Adapter
phy4 t2uh mt76x0 Ralink Technology, Corp.
MT7610U ("Archer T2U" 2.4G+5G WLAN Adapter
Last thing I can think of, the tests were not conducted
simultaneously, meaning they didn't all start or fail at once. I had
multiple successful connections with each one before they
independently failed.
Hope that helps.
Thanks,
Zero_Chaos
