Bhyve and Poor network speed with Intel X540-AT2

Hello,

I am running debian8 in a bhyve instance. The host has a 10g network and
uses Intel X540-AT2 NIC. The guest has a poor network speed in the order
of 2-3 kBps. However, if i disable the hardware offload features of the
NIC it brings the host speed from 10g to 1g, and bhyve shows 1g speed as
well. I use the following in rc.conf

 ifconfig_ix0="-rxcsum -txcsum  -vlanmtu  -vlanhwtso  -tso4 -tso6
-vlanhwtso -vlanhwcsum up"

Is there anyway around to get 10g speed on host and better speed in the
vm simultaneously?


Thanks

Rajil
