Hi all.

This patchset is just the first phase of switch and switch-ish device
support api in kernel. Note that the api will extend.

So what this patchset includes:
- introduce switchdev api skeleton for implementing switch drivers
- introduce rocker switch driver which implements switchdev api fdb and
bridge set/get link ndos

As to the discussion if there is need to have specific class of device
representing the switch itself, so far we found no need to introduce that.
But we are generally ok with the idea and when the time comes and it will
be needed, it can be easily introduced without any disturbance.

This patchset introduces switch id export through rtnetlink and sysfs,
which is similar to what we have for port id in SR-IOV. I will send iproute2
patchset for showing the switch id for port netdevs once this is applied.
This applies also for the PF_BRIDGE and fdb iproute2 patches.

iproute2 patches are now available here:
https://github.com/jpirko/iproute2-rocker

For detailed description and version history, please see individual patches.

Jiri Pirko (8):
bridge: rename fdb_*_hw to fdb_*_hw_addr to avoid confusion
net: make vid as a parameter for ndo_fdb_add/ndo_fdb_del
net: rename netdev_phys_port_id to more generic name
net: introduce generic switch devices support
rtnl: expose physical switch id for particular device
net-sysfs: expose physical switch id for particular device
rocker: introduce rocker switch driver
rocker: implement ndo_fdb_dump

Scott Feldman (9):
bridge: call netdev_sw_port_stp_update when bridge port STP status
changes
bridge: add API to notify bridge driver of learned FBD on offloaded
device
rocker: implement rocker ofdpa flow table manipulation
rocker: implement L2 bridge offloading
bridge: move private brport flags to if_bridge.h so port drivers can
use flags
bridge: add new brport flag LEARNING_SYNC
bridge: add new hwmode swdev
bridge: add brport flags to dflt bridge_getlink
rocker: add ndo_bridge_setlnk/getlink support for learning policy
