From: John Crispin Date: Tue, 7 Jul 2015 18:06:39 +0000 (+0000) Subject: ar71xx: Add support for Cisco-Linksys WAP4410N X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=08790c5ee8bfca46d0afe973e336e44e27e35a8c;p=openwrt%2Fstaging%2Flinusw.git ar71xx: Add support for Cisco-Linksys WAP4410N This patch adds support for the Cisco WAP4410N, an access point that uses the AR9132 SoC. Web upgrades from stock are not yet possible, UART access required for the initial flash.
