From: Kevin Darbyshire-Bryant Date: Fri, 28 Sep 2018 08:42:33 +0000 (+0100) Subject: kmod-sched-cake: don't gso fixup on fixed kernels X-Git-Tag: v19.07.0-rc1~2439 X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=b47614f9f18c7d1c24104ef1d53c8d1ac8920ba4;p=oweals%2Fopenwrt.git kmod-sched-cake: don't gso fixup on fixed kernels Kernels 4.14.73 & 4.9.140 include the gso fixup fix, so cake doesn't need to do it. Let's not waste cpu cycles by doing it in cake which could be really important on cpu constrained devices.
