Subject: [PATCH 065/179] brcmfmac: support station interface creation version
1, 2 and 3
To create virtual station interface for RSDB and VSDB, we add interface
creation version 1, 2 and 3 supports
The structures of each version are different and only version 3 and
later version are able to get interface creating version from firmware
side.
The patch has been verified two concurrent stations pings test with
interface create version 1:
89342(4359b1)-PCIE: 9.40.100
interface create version 2:
4373a0-sdio: 13.10.271
interface create version 3:
4373a0-sdio: 13.35.48
