2017-05-18net: dsa: include switchdev.h only onceVivien Didelot
DSA drivers and core use switchdev. Include switchdev.h only once, in the dsa.h public header, so that inclusion in DSA drivers or forward declarations of switchdev structures in not necessary anymore.

2017-05-08net: dsa: loop: Check for memory allocation failureChristophe Jaillet
If 'devm_kzalloc' fails, a NULL pointer will be dereferenced. Return -ENOMEM instead, as done for some other memory allocation just a few lines above.

2017-04-06net: dsa: loop: Initialize err in dsa_loop_vlan_dumpFlorian Fainelli
Dan's static checker reported the following: drivers/net/dsa/dsa_loop.c:223 dsa_loop_port_vlan_dump() error: uninitialized symbol 'err'. which could happen if we do hit the continue statement for each iteration of the loop. Initialize err to 0 here.

Dan's static analyzer reported the following: drivers/net/dsa/dsa_loop.c:181 dsa_loop_port_vlan_del() error: XXX uninitialized symbol 'pvid'. we were missing the assignment of pvid to ps->vid, so add that.

2017-04-01net: dsa: Mock-up driverFlorian Fainelli
This patch adds support for a DSA mock-up driver which essentially does the following: - registers/unregisters 4 fixed PHYs to the slave network devices - uses eth0 (configurable) as the master netdev - registers the switch as a fixed MDIO device against the fixed MDIO bus at address 31 - includes dynamic debug prints for dsa_switch_ops functions that can be enabled to get call traces This is a good way to test modular builds as well as exercise the DSA APIs without requiring access to real hardware. This does not test the data-path, although this could be added later on. Signed-off-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
