"Intel? Ethernet Controller X710/XXV710/XL710 Feature Support Matrix"
don't show support 100Mb link for any sw release for X710/XL710.

"Intel? Ethernet Connection X722 Feature Support Matrix" don't
have
string "100"

I'm guessing these are 10G copper LOMs using X722; those don't support
100Mb speeds.
