QCA988x Mesh mode support

Trying to get Mesh mode on a Compex WLE900VX ( QCA9880 hw2.0 ) IW reports that the mode and frame types are supported, but mesh isn't listed for the interface, might be related to #68 and #75 or might not...

( I'm trying to run AP and Mesh simultaneously )

iw shows that it should support mesh, but it isn't listed as a valid interface combination

on the other card ( WLE1216V2 - QCA9884 ) iw output is the same for the supported TX and RX frames and interface modes, but the valid interface combinations section shows "Mesh" ( not P2P ,.. interesting but irrelevant at the moment )-

This might be an invalid comparison as they are running different firmwares and are different chipsets, just iw Phy outputs are smiliar to a large extent , 10.4-ct( QCA9884 ) vs 10.1-ct ( CQA9880)
