From: Rosen Penev Date: Thu, 31 Oct 2019 18:58:51 +0000 (-0700) Subject: can-utils: Update to 2018.02.0 X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=f9041ad9b73e503de81d315bab0d4cdb906d13a5;p=feed%2Fpackages.git can-utils: Update to 2018.02.0 Switched to codeload for simplicity. Switched to PKG_INSTALL for consistency. Added PKG_BUILD_PARALLEL for faster compilation. Added extra utilities added by the newer version.
