2016-10-21net: remove MTU limits on a few ether_setup callersJarod Wilson
These few drivers call ether_setup(), but have no ndo_change_mtu, and thus were overlooked for changes to MTU range checking behavior. They previously had no range checks, so for feature-parity, set their min_mtu to 0 and max_mtu to ETH_MAX_MTU (65535), instead of the 68 and 1500 inherited from the ether_setup() changes. Fine-tuning can come after we get back to full feature-parity here.

2016-09-23net: dsa: add port fast ageingVivien Didelot
Today the DSA drivers are in charge of flushing the MAC addresses associated to a port when its STP state changes from Learning or Forwarding, to Disabled or Blocking or Listening. This makes the drivers more complex and hides the generic switch logic. Introduce a new optional port_fast_age operation to dsa_switch_ops, to move this logic to the DSA layer and keep drivers simple.

2016-08-24net: dsa: rename switch operations structureVivien Didelot
Now that the dsa_switch_driver structure contains only function pointers as it is supposed to, rename it to the more appropriate dsa_switch_ops, uniformly to any other operations structure in the kernel. No functional changes here, basically just the result of something like: s/dsa_switch_driver *drv/dsa_switch_ops *ops/g However keep the {un,}register_switch_driver functions and their dsa_switch_drivers list as is, since they represent the -- likely to be deprecated soon -- legacy DSA registration framework.

2016-04-28net: dsa: Provide CPU port statistics to master netdevFlorian Fainelli
This patch overloads the DSA master netdev, aka CPU Ethernet MAC to also include switch-side statistics, which is useful for debugging purposes, when the switch is not properly connected to the Ethernet MAC (duplex mismatch, (RG)MII electrical issues etc.). We accomplish this by retaining the original copy of the master netdev's ethtool_ops, and just overload the 3 operations we care about: get_sset_count, get_strings and get_ethtool_stats so as to intercept these calls and call into the original master_netdev ethtool_ops, plus our own. We take this approach as opposed to providing a set of DSA helper functions that would retrive the CPU port's statistics, because the entire purpose of DSA is to allow unmodified Ethernet MAC drivers to be used as CPU conduit interfaces, therefore, statistics overlay in such drivers would simply not scale. The new ethtool -S <iface> output would therefore look like this now: <iface> statistics p<2 digits cpu port number>_<switch MIB counter names> Signed-off-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: David S.
