Description and Notes

This card requires a kernel recompile to include Mellanox 1/10/40Gbit Ethernet support. Via menuconfig:

Device Drivers
  -> Network device support
    -> Ethernet driver support
      -> Mellanox Devices
        -> Mellanox Technologies 1/10/40Gbit Ethernet support

Three are also Mellanox OFED drivers, but they have been tricky to install.

The link LED gets lit, the interface is seen by the Raspberry Pi, but then when it tries to send or receive network traffic, errors like the following are printed to dmesg:

NETDEV WATCHDOG: eth1 (mlx4_core): transmit queue 1 timed out

See the linked GitHub issue for more details.
