X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=c305524617dcd617d698dfe2682f3212e698f781;p=openwrt%2Fstaging%2Fblogic.git rocker: Handle protodown notifications. protodown can be set by user space applications like MLAG on detecting errors on a switch port. This patch provides sample switch driver changes for handling protodown. Rocker PHYS disables the port in response to protodown.
