From 19e528dc9af29169fa7cdfa61071805fdef504c6 Mon Sep 17 00:00:00 2001 From: Po Liu Date: Wed, 24 Jun 2020 17:36:28 +0800 Subject: net: qos: add tc police offloading action with max frame size limit Current police offloading support the 'burst'' and 'rate_bytes_ps'. Some hardware own the capability to limit the frame size. If the frame size larger than the setting, the frame would be dropped. For the police action itself already accept the 'mtu' parameter in tc command. But not extend to tc flower offloading. So extend 'mtu' to tc flower offloading.
