* New getsockopt option to get socket cookieChenbo Feng2017-04-0814-0/+34
| | | | | | | | | | | Introduce a new getsockopt operation to retrieve the socket cookie for a specific socket based on the socket fd. It returns a unique non-decreasing cookie for each socket.

| * net/mlx5e: Set default RX moderation parameters on driver loadSaeed Mahameed2017-04-071-4/+4
| | | | | | | | | | | | | | | | | | | | RX moderation default parameters shouldn't be set in mlx5e_build_rx_cq_param since it would reset the values every time on netdev open/close. Instead, it should be set in mlx5e_set_rx_cq_mode_params which is called on driver load only.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Reuse the code for mlx5e_alloc_cq and mlx5e_alloc_drop_cq, as they have a similar flow. Prior to this patch, the CQEs in the "drop CQ" were not initialized, fixed it with the shared flow of alloc CQ. This is not a critical bug as the RQ connected to this CQ never moved to RTS, but still better to have this right.

Among these ports, The port from 0 to 4 are the user ports connecting with the remote devices while the port 5 and 6 are the CPU ports connecting into Mediatek Ethernet GMAC. For port 6, it can communicate with the CPU via Mediatek Ethernet GMAC through either the TRGMII or RGMII which could be controlled by phy-mode in the dt-bindings to specify which mode is preferred to use. And for port 5, only RGMII can be specified. However, currently, only port 6 is being supported in this DSA driver. The driver is made with the reference to qca8k and other existing DSA driver. The most of the essential callbacks of the DSA are already support in the driver, including tag insert for user port distinguishing, port control, bridge offloading, STP setup and ethtool operation to allow DSA to model each user port into a standalone netdevice as the other DSA driver had done.

* | net: ipv4: fix multipath RTM_GETROUTE behavior when iif is givenFlorian Larysch2017-04-071-4/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | inet_rtm_getroute synthesizes a skeletal ICMP skb, which is passed to ip_route_input when iif is given. If a multipath route is present for the designated destination, fib_multipath_hash ends up being called with that skb. However, as that skb contains no information beyond the protocol type, the calculated hash does not match the one we would see for a real packet. There is currently no way to fix this for layer 4 hashing, as RTM_GETROUTE doesn't have the necessary information to create layer 4 headers. To fix this for layer 3 hashing, set appropriate saddr/daddrs in the skb and also change the protocol to UDP to avoid special treatment for ICMP.

| * | qede: Correct XDP forward unmappingMintz, Yuval2017-04-073-14/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Driver is currently using dma_unmap_single() with the address it passed to device for the purpose of forwarding, but the XDP transmission buffer was originally a page allocated for the rx-queue. The mapped address is likely to differ from the original mapped address due to the placement offset. This difference is going to get even bigger once we support headroom. Cache the original mapped address of the page, and use it for unmapping of the buffer when completion arrives for the XDP forwarded packet.

| * | qede: Update receive statistic once per NAPIMintz, Yuval2017-04-071-10/+11
|/ / | | | | | | | | | | | | | | | | | | | | Currently, each time an ingress packet is passed to networking stack the driver increments a per-queue SW statistic. As we want to have additional fields in the first cache-line of the Rx-queue struct, change flow so this statistic would be updated once per NAPI run. We will later push the statistic to a different cache line. Signed-off-by: Yuval Mintz <Yuval.Mintz@cavium.com> Signed-off-by: David S. Miller <davem@davemloft.net>
