I reverted your patch, moved my build b= ack to 3.10.21 to match openwrt, felix reverted some stuff in netifd... ... and on first boot, somehow, all the wireless interfaces come up. After a reboot, most don't. doing openwrt's wifi up is also interesting with all sorts of failures trying to bring up different interfaces. So I suspect netifd has a race still. Afer we get that sorted, we can move onto trying to poke into the DMA tx error, or since it seems by hammering on it I can get an interface up I can move forward a bit, in parallel. --=20 Dave T=E4ht Fixing bufferbloat with cerowrt: http://www.teklibre.com/cerowrt/subscribe.= html
