Customer_type: Developer/Designer Product: Intel(R) Gigabit ET Quad Port Server Adapter OS: Red Hat Enterprise Linux 5.0* Kernel: linux-2.6.18-128.el5PAE Distribution_Version: Red Hat Enterprise Linux Server release 5.3 (Tikanga) Issue_Other_Versions: Yes Driver_Version: igb-3.0.22 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.
