From: Rafał Miłecki Date: Tue, 31 Jan 2017 20:00:51 +0000 (+0100) Subject: kernel: rename bgmac patches to squeeze them X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=7583de2e8fdc2fdcfb16dfd431590a4b4611bf52;p=openwrt%2Fstaging%2Fldir.git kernel: rename bgmac patches to squeeze them This is a pure rename without any changes. It makes maintaining bgmac simpler and will hopefully make adding new kernel a bit easier.
