In linux, the packet reception can be done efficiently through the usage of
ethernet sockets.
In FreeBSD, one of the option is by using the BPF. But, as already commented, BPF
is not a high performance device.
So, Can anyone give an alternative

VM gurus: This seems to be bug!
This morning I sent an email (attached below) regarding a hang at the
vmopar state. While waiting for responses, I use Google Advanced Groups
Search looking for vmopar in all FreeBSD archived mailing lists and I
did find the following message posted by Xavier
As Cisco switches have STP enabled by default on all ports, maybe a reboot of
an 4.4 system is seen as a change in link state, so Catalyst holds the port
STP-blocked for a couple of seconds before putting it to forwarding state. Did
you try disabling STP on Catalyst eth ports?
