Subject: mac80211: brcmsmac: use firmware extracted from proprietary driver
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=8086b7a75004e9f0ec71d5ffc9afce94a075087b;p=openwrt%2Fstaging%2Fstintel.git

mac80211: brcmsmac: use firmware extracted from proprietary driver

The firmware from linux-firmware does not support the rev 17 core found
in a bcm4716. The firmware extracted from the proprietary driver
supports this core. Use this firmware instead by default.
