According to the documentation I can find, the X520-DA2 NIC should support fiber optics SFP+ modules. The SFP+ modules does work in another 82599 based NIC in the same machine (engineering sample from PJ). According to the driver code (ixgbe) the 82599 and the X520 looks like they share the same init code. What is going on with the X520-DA2 model? Extra info below: Tested with: Kernel: 3.2.0-net-next-14778-g117ff42 (ethtool -i) driver: ixgbe version: 3.6.7-k firmware-version: 0x18f60001 bus-info: 0000:24:00.0 The working NIC reports firmware-version: 0xd87c0000. The kern.log error: ixgbe 0000:24:00.1: failed to load because an unsupported SFP+ module type was detected. ixgbe 0000:24:00.1: Reload the driver after installing a supported module. The PCI vendor ID's are also almost the same between the two cards: # None working X520-DA2 NIC lspci -n | grep 24:00. 24:00.0 0200: 8086:10fb (rev 01) 24:00.1 0200: 8086:10fb (rev 01) # Working NIC lspci -n | grep 12:00. 12:00.0 0200: 8086:10fb 12:00.1 0200: 8086:10fb -- Best regards, Jesper Dangaard Brouer ComX Networks A/S Linux Network Kernel Developer Cand.
