Issue: We recently purchased two 'Intel(R) Gigabit ET Quad Port Svr 
Adptr' cards for a large industrial control system. The NIC works fine 
for most ethernet traffic, but rejects certain PROFINET packets. These 
packets can only be received if 'promiscuous' mode is enabled. The 
packets that are rejected are less than 200 bytes, but do use the 
standard PROFINET VLAN field. Other PROFINET packets are received fine. 
The network is private and dedicated to PROFINET traffic. The server 
does not need a VLAN configuration. We replaced the card with an older 
single-port PRO/1000 NIC (i.e. uses the e1000e driver) and the problem 
disappears. Other 3-Com and Broadcom NICs also work correctly. We need 
to get this driver fixed, or get the cards replaced with PRO/1000 based 
Quad-port NICs. Let me know if you need more information.

Thanks,
Greg
