Changing the rx_checksum settings

Hi,

I am new to FreeBSD. What I am trying to do is to disable the rx checksum for my interface. I have tried using:
# ifconfig ql0 -tso
but still if I run ifconfig(8) I am able to see rx_checksum, tso etc in the options that are listed for my interface.

Please help..
 
Not all drivers support off-loading the checksums to the card. What driver are you using?
 
Sorry for the late response. I am using the qlxgbe driver. Got a way to disable the rxcsum. But now I'm stuck at how to disable/enable LRO, as it does not show up in the ifconfig output. Also, is there a way to check the LRO counters when running traffic?
