Subject: niu lock-up (Transmit timed out, resetting) and NETDEV WATCHDOG

Hello

Using niu driver for this card: Oracle/SUN Multithreaded 10-Gigabit
Ethernet Network Controller
after a period (often less than 24 hours) the interface will hang with
errors every 5 seconds
"niu: xxx: eth2: Transmit timed out, resetting"

Sometimes also in syslog are messages
WARNING: at sch_generic:255 dev_watchdog
NETDEV WATCHDOG: eth2 (niu): transmit queue 10 timed out

Does anyone know which driver revision has fixed this problem or if
it's still buggy?

Thanks!

Andrew

P.S. My guess is the commit on 2012-10-02 ??
