This adds support for CBS reconfiguration using the TC application. A new callback was added to TC ops struct and another one to DMA ops to reconfigure the channel mode. Tested in GMAC5.10.

Saeed Mahameed says: ==================== mlx5e-updates-2018-06-28 mlx5e netdevice driver updates: - Boris Pismenny added the support for UDP GSO in the first two patches. Impressive performance numbers are included in the commit message, @Line rate with ~half of the cpu utilization compared to non offload or no GSO at all. - From Tariq Toukan: - Convert large order kzalloc allocations to kvzalloc. - Added performance diagnostic statistics to several places in data path. From Saeed and Eran, - Update NIC HW stats on demand only, this is to eliminate the background thread needed to update some HW statistics in the driver cache in order to report error and drop counters from HW in ndo_get_stats. ==================== Signed-off-by: NDavid S.

Jakub Kicinski says: ==================== net: Geneve options support for TC act_tunnel_key Simon & Pieter say: This set adds Geneve Options support to the TC tunnel key action. It provides the plumbing required to configure Geneve variable length options. The options can be configured in the form CLASS:TYPE:DATA, where CLASS is represented as a 16bit hexadecimal value, TYPE as an 8bit hexadecimal value and DATA as a variable length hexadecimal value. Additionally multiple options may be listed using a comma delimiter. v2: - fix sparse warnings in patches 3 and 4 (first one reported by build bot). ==================== Signed-off-by: NDavid S.

Check the tunnel option type stored in tunnel flags when creating options for tunnels. Thereby ensuring we do not set geneve, vxlan or erspan tunnel options on interfaces that are not associated with them. Make sure all users of the infrastructure set correct flags, for the BPF helper we have to set all bits to keep backward compatibility.

The present TX workrequest(FW_ETH_TX_PKT_WR) cant be used for host->vf communication, since it doesn't loopback the outgoing packets to virtual interfaces on the same port. This can be done using FW_ETH_TX_PKT_VM_WR. This fix depends on ethtool_flags to determine what WR to use for TX path. Support for setting this flags by user is added in next commit.

This feature is actually already supported by sk->sk_reuse which can be set by socket level opt SO_REUSEADDR. But it's not working exactly as RFC6458 demands in section 8.1.27, like: - This option only supports one-to-one style SCTP sockets - This socket option must not be used after calling bind() or sctp_bindx(). Besides, SCTP_REUSE_PORT sockopt should be provided for user's programs. Otherwise, the programs with SCTP_REUSE_PORT from other systems will not work in linux. To separate it from the socket level version, this patch adds 'reuse' in sctp_sock and it works pretty much as sk->sk_reuse, but with some extra setup limitations that are needed when it is being enabled. "It should be noted that the behavior of the socket-level socket option to reuse ports and/or addresses for SCTP sockets is unspecified", so it leaves SO_REUSEADDR as is for the compatibility. Note that the name SCTP_REUSE_PORT is somewhat confusing, as its functionality is nearly identical to SO_REUSEADDR, but with some extra restrictions. Here it uses 'reuse' in sctp_sock instead of 'reuseport'. As for sk->sk_reuseport support for SCTP, it will be added in another patch. Thanks to Neil to make this clear. v1->v2: - add sctp_sk->reuse to separate it from the socket level version. v2->v3: - improve changelog according to Marcelo's suggestion.
