This adds a DSA driver for:
Vitesse VSC7385 SparX-G5 5-port Integrated Gigabit Ethernet Switch
Vitesse VSC7388 SparX-G8 8-port Integrated Gigabit Ethernet Switch
Vitesse VSC7395 SparX-G5e 5+1-port Integrated Gigabit Ethernet Switch
Vitesse VSC7398 SparX-G8e 8-port Integrated Gigabit Ethernet Switch
These switches have a built-in 8051 CPU and can download and execute
firmware in this CPU. They can also be configured to use an external
CPU handling the switch in a memory-mapped manner by connecting to
that external CPU's memory bus.
This driver (currently) only takes control of the switch chip over
SPI and configures it to route packages around when connected to a
CPU port. The chip has embedded PHYs and VLAN support so we model it
using DSA as a best fit so we can easily add VLAN support and maybe
later also exploit the internal frame header to get more direct
control over the switch.
The four built-in GPIO lines are exposed using a standard GPIO chip.

In the Broadcom Cygnus SoC, the brcm tag needs to be inserted
in between the mac address and the ether type (should use
'DSA_PROTO_TAG_BRCM') for the packets sent to the internal
b53 switch.
Since the Cygnus was added with the BCM58XX device id and the
BCM58XX uses 'DSA_PROTO_TAG_BRCM_PREPEND', the data path is
broken, due to the incorrect brcm tag location.
Add a new b53 device id (BCM583XX) for Cygnus family to fix the
issue. Add the new device id to the BCM58XX family as Cygnus
is similar to the BCM58XX in most other functionalities.

We had several issues that would make the programming of IPv6 rules both

- the chain ID that we would be asking the hardware to put in the
packet's Broadcom tag would be off by one, it would return one of the
two indexes, but not the one user-space specified
- when an user specified a particular location to insert a CFP rule at,
we would not be returning the same index, which would be confusing if
nothing else
- finally, like IPv4, it would be possible to overflow the last entry by
re-programming it
Fix this by swapping the usage of rule_index[0] and rule_index[1] where
relevant in order to return a consistent and correct user-space
experience.

the necessary operation for PHYLINK to work: mac_config, mac_link_up,
mac_link_down and validate. We can now entirely get rid of most of what

The DSA stack passes received PTP frames to this driver via

queues the frame and kicks the worker thread. The work callback reads
out the latched receive time stamp and then works through the queue,
delivering any non-matching frames without a time stamp.
If a new frame arrives after the worker thread has read out the time
stamp register but enters the queue before the worker finishes
processing the queue, that frame will be delivered without a time
stamp.
This patch fixes the race by moving the queue onto a list on the stack
