This patchset is just the first phase of switch and switch-ish device support api in kernel. Note that the api will extend (our complete work can be pulled from https://github.com/jpirko/net-next-rocker). So what this patchset includes: - introduce switchdev api for implementing switch drivers (so far only linux bridge fdb offload is covered) - introduce rocker switch driver which implements switchdev api 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. For detailed description, please see individual patches.
