Public bug reported: Hi all,
As mentioned on IRC, here is the problem: 2 x 1GbE LAN via Intel® i350-AM21 2 port GbE interface card is not being picked up under Ubuntu either using kernel in-tree driver or Intel provided driver on their website. These NIC(s) are used within the Supermicro H11DSi board (https://www.supermicro.com/en/products/motherboard/H11DSi) and several other variants of their motherboard. I tried two ways to fix this issue: (1) Building the Intel provided driver is not possible right now on newer kernels (see bug: https://forums.intel.com/s/question/0D50P00004dfC66SAE/intel-350t4-igb- driver-and-kernel-54-build-error?language=en_US). It is using old headers and even with some corrections it fails to compile with some detailed code corrections. Supermicro provides the exact same drivers as found on the Intel website on a CD for RHEL/SuSE which also fails to compile for the same reason. (2) The kernel in-tree Intel driver fails to identify these Intel interfaces as it appears the device ID is missing (https://github.com/torvalds/linux/blob/6f0d349d922ba44e4348a17a78ea51b7135965b1/drivers/net/ethernet/intel/igb/e1000_hw.h): In the header file we see the identifiers: #define E1000_DEV_ID_I350_COPPER 0x1521 #define E1000_DEV_ID_I350_FIBER 0x1522 #define E1000_DEV_ID_I350_SERDES 0x1523 #define E1000_DEV_ID_I350_SGMII 0x1524 lspci shows us a missing identifier (0x151f): 01:00.0 Ethernet controller [0200]: Intel Corporation Device [8086:151f] (rev 01) 01:00.1 Ethernet controller [0200]: Intel Corporation Device [8086:151f] (rev 01) It could be that a simple addition of the identifier in the kernel fixes the issue, although issue (1) still exists and Intel needs to re-build and test their code on the latest 5.X Kernel.
