Subject: broadcom-wl: Add 'N' mode support to broadcom-wl
X-Git-Url: https://git.archive.openwrt.org/?p=openwrt.git;a=commitdiff_plain;h=8a179b4f384e639bdd4553efe696535c33f54ca4

broadcom-wl: Add 'N' mode support to broadcom-wl

This is partly based on patches sent by Łukasz Kwestarz (See https://lists.openwrt.org/pipermail/openwrt-devel/2012-March/014356.html).
