Detailed statistics on em(4) driver

[Bernd]

Hi,

I've got problems with increasing Ierrs on several machines with several 
em(4) interfaces. Is there a way to get *detailed* information on these?

# netstat -I em3 -d
Name    Mtu   Network     Address              Ipkts Ierrs    Opkts 
Oerrs Colls Drop
em3     1500  <Link>      de:ad:be:ef          95655063 435896 63427593  
   0     0    0
em3     1500  fe80::%em3/ fe80::xx:ff:ffe      95655063 435896 63427593  
   0     0    0

is not that verbose.

Thanks in advance,

Bernd
