[Thiago A. Corrêa]

Hi Peter,

    I'm newbie with this git thing, so please bear with me...

    Please pull git clone git://git.buildroot.net/~correa/git/buildroot.git for:

 * Update Linux Advanced to 2.6.29.2 - this fixes iptables compile
 * Add dl folder to gitignore
 * Update atngw100_defconfig

Kind Regards,
   Thiago A. Correa
