* net: dsa: Introduce dsa_get_cpu_port()Florian Fainelli2017-06-131-15/+16
| | | | | | | | | | | Introduce a helper function which will return a reference to the CPU port used in a dsa_switch_tree. Right now this is a singleton, but this will change once we introduce multi-CPU port support, so ease the transition by converting the affected code paths.

* net: dsa: Associate slave network device with CPU portFlorian Fainelli2017-06-131-1/+3
| | | | | | | | | | | | In preparation for supporting multiple CPU ports with DSA, have the dsa_port structure know which CPU it is associated with. This will be important in order to make sure the correct CPU is used for transmission of the frames. If not for functional reasons, for performance (e.g: load balancing) and forwarding decisions.

This is a preliminary change to supporting multiple CPU port interfaces.

* net: dsa: Remove master_netdev and use dst->cpu_dp->netdevFlorian Fainelli2017-06-131-12/+9
| | | | | | | | | | | | | | | | | | In preparation for supporting multiple CPU ports, remove dst->master_netdev and ds->master_netdev and replace them with only one instance of the common object we have for a port: struct dsa_port::netdev. ds->master_netdev is currently write only and would be helpful in the case where we have two switches, both with CPU ports, and also connected within each other, which the multi-CPU port patch series would address. While at it, introduce a helper function used in net/dsa/slave.c to immediately get a reference on the master network device called dsa_master_netdev().

| | | | | | | | | | | We need to push the chain index down to the drivers, so they have the information to which chain the rule belongs. For now, no driver supports multichain offload, so only chain 0 is supported. This is needed to prevent chain squashes during offload for now. Later this will be used to implement multichain offload.

The conditions for such an error to occur are that we have a port of our switch that is not disabled, and has the same port number as a PHY address (say both 5) that can be probed using the DSA slave MII bus. We end-up having this slave network device find a PHY at the same address as our port number, and we try to attach to it. A slave network (e.g: port 0) has already attached to our PHY device, and we try to re-attach it with a different network device, but since we ignore the error we would end-up initializating incorrect device references by the time the slave network interface is opened. The code has been (re)organized several times, making it hard to provide an exact Fixes tag, this is a bugfix nonetheless.

It also overlapped with Jiri's change to guard the rhashtable_remove_fast() call with a check against tc_skip_sw(). 5) In mlx4, a revert bug fix in 'net' overlapped with some unrelated changes in 'net-next'. 6) In geneve, a stale header pointer after pskb_expand_head() bug fix in 'net' overlapped with a large reorganization of the same code in 'net-next'. Since the 'net-next' code no longer had the bug in question, there was nothing to do other than to simply take the 'net-next' hunks. Signed-off-by: David S. Miller <davem@davemloft.net>
