[OpenWrt-Devel] [PATCH v4 3/5] mac80211: make ath10k firmware v2 selectable

[Günther Kelleter]

Added option for old firmware version (10.1 API v2). It seems that recent
firmware versions are constantly crashing (at least on a QCA9880-BR4A-R) and
this provides the option to select an older version instead.
