2016-04-08mlxsw: Do not pass around driver_priv directlyJiri Pirko1-4/+4
Instead of that, pass mlxsw_core and use a helper to get driver priv from driver code. Looks much cleaner that way. Signed-off-by: Jiri Pirko <jiri@mellanox.com> Reviewed-by: Ido Schimmel <idosch@mellanox.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2016-04-08mlxsw: Move devlink port registration into common core codeJiri Pirko1-19/+11
Remove devlink port reg/unreg from spectrum and switchx2 code and rather do the common work in core. That also ensures code separation where devlink is only used in core.c.

2016-04-06mlxsw: reg: Introduce per priority countersIdo Schimmel1-1/+2
We are going to add support for PFC as part of DCB ops, which requires us to report the number of PFC frames sent and received per priority. Add per priority counters in order to report number of PFC frames sent and received per priority.

Conflicts: drivers/net/usb/asix_common.c net/ipv4/inet_connection_sock.c net/switchdev/switchdev.c In the inet_connection_sock.c case the request socket hashing scheme is completely different in net-next. The other two conflicts were overlapping changes. Signed-off-by: David S. Miller <davem@davemloft.net>
2015-10-16mlxsw: Enable configuration of flooding domainsIdo Schimmel1-1/+2
As part of the introduction of L2 offloads, allow different ports to join/leave the flooding domain, according to user configuration. Signed-off-by: Ido Schimmel <idosch@mellanox.com> Signed-off-by: Jiri Pirko <jiri@mellanox.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2015-10-15mlxsw: Add trap group for control packetsIdo Schimmel1-0/+5
Previously, we trapped flooded and control packets using the same trap group. This can cause flooded packets to overflow the PCI bus and prevent control packets (e.g. STP, LACP) from getting to the CPU. Solve this by splitting the RX trap group to RX and control, which allows us to configure a policer on the first, thereby preventing it from overflowing the PCI bus.

2015-10-15mlxsw: Simplify traps creationIdo Schimmel1-5/+1
The Host Trap Group Table (HTGT) register configures trap groups, which are populated with trap IDs using the Host PacKet Trap (HPKT) register. However, a trap ID can only be present inside one trap group (the last configured). Instead of passing both the trap group and ID for the function that packs HPKT, pass only the trap ID and derive from it the trap group.

2015-08-09mlxsw: Fix use-after-free bug in mlxsw_sx_port_xmitIdo Schimmel1-1/+3
Store the length of the skb before transmitting it and use it for stats instead of skb->len, since skb might have been freed already.

2015-08-09mlxsw: Simplify mlxsw_sx_port_xmit functionIdo Schimmel1-15/+10
Previously we only checked if the transmission queue is not full in the middle of the xmit function. This lead to complex logic due to the fact that sometimes we need to reallocate the headroom for our Tx header. Allow the switch driver to know if the transmission queue is not full before sending the packet and remove this complex logic.

2015-08-09mlxsw: Make system port to local port mapping explicitIdo Schimmel1-0/+18
System ports are unique identifiers in a multi-ASIC environment that represent all the available ports in the system. Local ports on the other hand, are unique only within the local ASIC. Since system port to local port mapping is not part of the HW-SW contract and since only single-ASIC configurations are currently supported, set an explicit 1:1 mapping by configuring the Switch System Port Record (SSPR) register.

Benefit from the previously introduced Mellanox Switch infrastructure and add driver for SwitchX-2 ASIC. Note that this driver is very simple now. It implements bare minimum for getting device to work on slow-path. Fast-path offload functionality is going to be added soon.
