Description Val Packett 2020-01-23 19:20:00 UTC 
Not a serious problem but something I've noticed — for the same cable, an Intel (ix) card correctly shows:

        media: Ethernet autoselect (10Gbase-Twinax <full-duplex,rxpause,txpause>)

While mlx4en (ConnectX-2) shows:

        media: Ethernet autoselect (10Gbase-SR <full-duplex,rxpause,txpause>)

The same situation happens for sfxge (Solarflare) when using DAC cabling.
