em0 and FreeBSD8.1

[Graeme Dargie]

Hello All,

I installed 8.1 yesterday on vmware exsi, all seemed to go fine, but
today I noticed when I fired up phpsysinfo a lot of dropped packets.

        media: Ethernet autoselect (1000baseT <full-duplex>)
        status: active


The machine that vmware runs on has intel gb based nics and I also run
pfsense as my router firewall on the same vmware exsi machine and it has
not dropped a packet.

The only difference I can see is according to phpsysinfo the 8.1 machine
shows -	Intel Corporation - Gigabit Ethernet Controller (copper)
(82545EM)
Where as the pfsense vm shows em0: Intel(R) PRO/1000 Network Connection
6.9.6


Any one any ideas why this is showing dropped packets.
