Adds UCLASS_DSA class supporting switches that follow the Distributed
Switch Architecture (DSA). These switches rely on the presence of a
management switch port connected to an Ethernet controller capable of
receiving frames from the switch. This host Ethernet controller is

/**
* DSA stands for Distributed Switch Architecture and it is infrastructure
* intended to support drivers for Switches that rely on an intermediary
* Ethernet device for I/O. These switches may support cascading allowing
* them to be arranged as a tree.
* DSA is documented in detail in the Linux kernel documentation under
* Documentation/networking/dsa/dsa.txt
* The network layout of such a switch is shown below:
*
* |------|
* | eth0 | <--- master eth device (regular eth driver)
* |------|
* ^ |
* tag added by switch -->| |
* | |
* | |<-- tag added by DSA driver
* | v
* |--------------------------------------|
* | | CPU port | | <-- DSA (switch) device
* | ------------ | (DSA driver)
* | _________ _________ _________ |
* | | port0 | | port1 | ... | portn | | <-- ports as eth devices
* |-+-------+--+-------+-------+-------+-| ('dsa-port' eth driver)
*
* In U-Boot the intent is to allow access to front panel ports (shown at the
* bottom of the picture) through the master Ethernet dev (eth0 in the picture).
* Front panel ports are presented as regular Ethernet devices in U-Boot and
* they are expected to support the typical networking commands.
* In general DSA switches require the use of tags, extra headers added both by
* software on Tx and by the switch on Rx. These tags carry at a minimum port
* information and switch information for cascaded set-ups.
* In U-Boot these tags are inserted and parsed by the DSA switch driver, the
* class code helps with headroom/tailroom for the extra headers.
*
* TODO:
* - handle switch cascading, for now U-Boot only supports stand-alone switches.
* - Add support to probe DSA switches connected to a MDIO bus, this is needed
* to convert switch drivers that are now under drivers/net/phy.
