Subject: brcm47xx: improve cpuport detection for filesafe
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=9de704a03bd40c5ebfdd93106f806bd1a52cf7a7;p=openwrt%2Fstaging%2Fynezz.git

brcm47xx: improve cpuport detection for filesafe

Do not try to load bcm57xx.ko any more this is not needed for kernel 2.6 and 3.X
Ask the switch driver where the CPU port is.
