atl1c: dont use highprio tx queue
This driver attempts to use two TX rings but lacks proper support :
1) IRQ handler only takes care of TX completion on first TX ring
2) the stop/start logic uses the legacy functions (for non multiqueue
drivers)
This means all packets witk skb mark set to 1 are sent through high
queue but are never cleaned and queue eventualy fills and block the
device, triggering the infamous "NETDEV WATCHDOG" message.
Lets use a single TX ring to fix the problem, this driver is not a real
multiqueue one yet.
Minimal fix for stable kernels.
