Well I picked up a MCX311A card because I need a 4x PCIe 10-Gigabit Ethernet card for my firewall.
The card is so small it is amazing. Half the height of a Low Profile bracket. One SFP+ socket.
They are selling for $27 bucks used on ebay so I bought one.
I was happy to find out that it works fine at 10GbE with no kernel modifications necessary.
/etc/rc.conf
ifconfig_mlxen0="DHCP"
/boot/loader.conf
mlx4en_load="YES"
This is using a Finnstar SFP+ module to a 2m fiber LC-LC om3 dualmode cable connected to my Aruba switch.
I am using the Aruba 10GbE ports as normal DHCP ports instead of uplinks for now. I have a Netapp 10G switch but need to learn it..
Will report back in the future with some speeds between FreeBSD 10GbE devices like Chelsio T420 and Intel X520-DA2.
