Description (last modified by )
The MT26448 chipset is available in low-cost SFP+ network cards. We could test our network stack at 10 Gbit speeds if we had at least one driver ported over from FreeBSD.
A search on ebay for "Mellanox Connectx-2" will find quite a few of these low-cost 10Gbit cards.

If you want a 10Gb Ethernet driver, though, I can look at porting https://www.freebsd.org/cgi/man.cgi?query=ixgbe&apropos=0&sektion=4&manpath=FreeBSD+11.2-RELEASE+and+Ports&arch=default&format=html or the like.

Or any of these, really: https://www.freebsd.org/cgi/man.cgi?apropos=1&manpath=freebsd-release-ports&query=10Gb
Hmm, the mlx4en drivers do appear in that list, so maybe they are in FreeBSD now. The manpage for them states that they need the LinuxKPI compat layer though, so porting them is still infeasible.

ah. lame. Didn't realize it used the FreeBSD Linux compatibility layers.
For reference, the drivers are here:

Remove milestone for tickets with status = closed and resolution != fixed
MT26448 is supported only by an external driver from Mellanox, not a driver in FreeBSD itself; and said driver requires FreeBSD's linuxkpi compatibility layer, as well as about ~2-4M other lines of code (I didn't accurately count) that it brings with it. So this is not feasible in the slightest.
