For over a year LACP teaming and VLAN support with Intel NICs has been broken in Windows 10.
In public Intel seems keen to release working drivers, and are blaming Microsoft for breaking things. Microsoft seems to be saying nothing.
However, I’m having an awfully hard time believing that Intel and Microsoft can’t get an issue like this fixed quickly if they wanted to.
Without LACP teaming, your only choice for more bandwidth is a 10Gb NIC.
I wonder how many extra NICs Intel has sold to Windows 10 users in the last year or so?
