[PATCH net-next V1 00/12] QoS and VxLAN offloads support for Mellanox 100G mlx5 driver

[Saeed Mahameed]

Hi Dave,

This patch series introduces QoS IEEE dcbnl support for
PFC, ETS and max rate.

In addition we added VxLAN support and introduced a patch
that modifies the driver to report checksum complete in RX path 
for all IP (tunneled and non-tunneled) traffic which is non HW LRO.

This series is applied on top of the latest mlx5_ifc and NDO fixes 
we sent to the net tree:
	net/mlx5e: Use static constant netdevice ndos
	net/mlx5e: Remove select queue ndo initialization
	net/mlx5: Use offset based reserved field names in the IFC header file

The QoS patches depend on the IFC change since they expose new fields in 
the driver/firmware API. Both QoS and VxLAN patches depend on the NDO changes,
since they add new ndo entries.

Changes from V0:
	- Added change log comments on default_vlan_prio and why we use 
          MLX5E_MAX_NUM_TC on netdev creation.
	- Fixed Copyright notes to 2016 for new files.
	- Fixed a copy-paste bug in "Add TX stateless offloads for tunneling" 
          to use inner_tcp_hdrlen(skb) rather than tcp_hdrlen(skb) for 
          encapsulated LSO packets.

Saeed.

[PATCH net-next V1 01/12] net/mlx5: Introduce a new header file for physical port functions

[Saeed Mahameed]

From: Achiad Shochat <achiad@mellanox.com>

All the device physical port access functions are implemented in the
port.c file.
We just extract the exposure of these functions from driver.h into a
dedicated header file called port.h.

[PATCH net-next V1 04/12] net/mlx5e: Support DCBNL IEEE ETS

[Saeed Mahameed]

Support the ndo_setup_tc callback and the needed methods
for multi TC/UP support, and removed the default_vlan_prio
from mlx5e_priv which is always 0, it was replaced with
hardcoded "0" in the new select queue method.

For that we now create MAX_NUM_TC num of TISs (one per prio)
on netdevice creation instead of priv->params.num_tc which
was always 1.

So far each channel had a single TXQ, Now each channel has a
TXQ per TC (Traffic Class).

Added en_dcbnl.c which implements the set/get DCBNL IEEE ETS,
set/get dcbx and registers the mlx5e dcbnl ops.

We still use the kernel's default TXQ selection method to select the
channel to transmit through but now we use our own method to select
the TXQ inside the channel based on VLAN priority.

In mlx5, as opposed to mlx4, tc group N gets lower priority than
tc group N+1.

Use checksum complete for all IP packets, unless they are HW LRO,
in which case, use checksum unnecessary.

[PATCH net-next V1 10/12] net/mlx5e: Add netdev support for VXLAN tunneling

[Saeed Mahameed]

From: Matthew Finlay <matt@mellanox.com>

If a VXLAN udp dport is added to device it will:

   - Configure the hardware to offload the port (up to the max
     supported).
   - Advertise NETIF_F_GSO_UDP_TUNNEL and supported hw_enc_features.

Hi Saeed,

I just changed the signature on the setup_tc ndo hook so you will
need to change this to something like,

static int __mlx5e_setup_tc(struct net_device *dev, u32 handle,
			    __be16 proto, struct tc_to_netdev *tc)
{
	if (handle != TC_H_ROOT || tc->type != TC_SETUP_MQPRIO)
		return -EINVAL;
	return mlx5e_setup_tc(dev, tc->tc)
}


and then use __mlx5e_setup_tc() to populate the ndo op hook. If you
look at the mlx4 drivers I did this change there already.

Other than that nice to see another dcb supporting driver.

Thanks,
John

Hi John,

Thanks for pointing that out, will fix this out.

I guess we don't want VF drivers to control the uplink port QoS
arbiter, PFC setup and such, agree -- I gave this comment on V0
and you somehow missed addressing that, please do for V2.

Agree, sorry I missed your comment on V0, will fix it in V3 along with
John's comment.
