Subject: mwl8k: Send BASTREAM firmware commands per vif
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=f95275c48b60fc486517f05da0800357dfd3ce2f;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

mwl8k: Send BASTREAM firmware commands per vif

The firmware supports 8 macid's corresponding to 8 BSS that can be
created in an MBSS environment. Currently, BASTREAM commands were always
sent with macid 0. This macid is used to configure the hardware ampdu
registers with appropriate BSS address in an MBSS environment.
This mac address is used by the hardware for various ampdu related requirements
e.g. source address in BAR generation, BA interpretation e.t.c.
Using invalid macid results in this mac address not getting appropriately
configured in the hardware which results in issues during ampdu traffic.

Fix this by sending the BASTREAM commands with appropriate macid.
