sch_htb: Allow HTB quantum parameter in offload mode
The current implementation of HTB offload returns the EINVAL error for quantum parameter. This patch removes the error returning checks for 'quantum' parameter and populates its value to tc_htb_qopt_offload structure such that driver can use the same. Add quantum parameter check in mlx5 driver, as mlx5 devices are not capable of supporting the quantum parameter when htb offload is used. Report error if quantum parameter is set to a non-default value. Signed-off-by: Naveen Mamindlapalli <naveenm@marvell.com> Signed-off-by: Hariprasad Kelam <hkelam@marvell.com> Signed-off-by: David S.
