Subject: broadcom-wl: fix two problems when more then one wifi card is available.
X-Git-Url: http://git.openwrt.org/?a=commitdiff_plain;h=1293532ae52250c626b765149e10144f9bccb82e;p=openwrt%2Fsvn-archive%2Farchive.git

broadcom-wl: fix two problems when more then one wifi card is available.

* The device should get a unique name at the beginning and not wl%d
* load the nvram just one time into the own buffer also when there is
  more than one device.

Backport of r34381.
