Subject: ip doesn't handle vxlan id and group correctly

Hello,

it seems that ip doesn't handle combination of vxlan id and group
correctly. As you can see in attached script, I'm trying to create
multiple vxlans all with different combination of group and vxlan id. I
can create vxlans with different ids in same group, different ids in
different groups but I cannot create vxlan with same id in different
group, creation ends with "Error: A VXLAN device with the specified VNI
already exists.". Tested on current version 5.3.0 on arch linux.

Best regards,

Ondrej Flidr
