Subject: brcm47xx: bgmac: allow bigger et_swtype nvram variable
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=57c6730ed623e347ed8eae420e5e2fa6e67ebecc;p=openwrt%2Fstaging%2F981213.git

brcm47xx: bgmac: allow bigger et_swtype nvram variable

Without this patch it is impossible to read et_swtype, because the 1
byte space is needed for the terminating null byte. Now it should be
possible to read decimal and hex vars of max 8 bit.
