From: Jian Shen <shenjian15@huawei.com> mainline inclusion from mainline-v5.13-rc1 commit ae4811913f576d3a891e2ca8a3ad11746f644c69 category: feature bugzilla: 173966 CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?i... ---------------------------------------------------------------------- The hardware supports to parse and match the traffic class field of IPv6 packet for flow director, uses the same tuple as ip tos. So removes the limitation of configure 'tclass' by driver. Signed-off-by: Jian Shen <shenjian15@huawei.com> Signed-off-by: Huazhong Tan <tanhuazhong@huawei.com> Signed-off-by: David S.
