[PATCH] Increase the tx queue to 512 descriptors to fix performance problem.
Now that we have a host timer based tx wakeup it waits for 64 packets or timeout before processing them. This might cause the guest to run out of tx buffers while the host holds them up. This is a temporal solution to quickly bring back performance to 800mbps. But a better fix will soon be sent (its not the only problem). Signed-off-by: Dor Laor <dor.laor@qumranet.com> ---
