I do not think it’s a problem with txd, as the traffic is very light(about 500packets/sec). Anyways, here are the values.

hw.igb.rx_process_limit: 100
hw.igb.num_queues: 0
hw.igb.header_split: 0
hw.igb.max_interrupt_rate: 8000
hw.igb.enable_msix: 1
hw.igb.enable_aim: 1
hw.igb.txd: 1024
hw.igb.rxd: 1024


Forgot to mention, my version of driver is r275836 on stable/10.
