[PATCH] net/mlx5/windows: fix match criteria in flow creation

[Itai Sharoni]

> Why adding only NVGRE?

We added NVGRE support in response to a specific client request. 
Unfortunately, we don't have the capacity to test and validate other 
tunnel types for this upcoming release. We're focusing our resources 
on ensuring NVGRE works reliably.

We definitely see value in expanding tunnel support on Windows in 
future releases. We can consider adding other tunnel types (VXLAN, 
GRE, GENEVE, etc.) as a feature for a future release once we have 
the resources to properly test and validate them.

> Should we mention which tunnels are supported on Windows in the doc?

Good suggestion, I've added documentation in v2 of the patch. The 
documentation now lists NVGRE as supported and notes that it requires 
DevX dynamic insertion mode. This makes it easy to expand the list 
when we add more tunnel types in future releases.
