This patch series adds support to pretty dump the registers of user
ports created by the kernel "dsa" subsystem.
The first patch adds the base support for "dsa" interfaces.
The second patch adds the boilerplate for the "mv88e6xxx" DSA driver,
all using 32 registers of 16 bits, the switch ID being assigned
by the kernel driver into the regs version. Support for other DSA
drivers such as "b53" or "ksz" can be added similarly later. Because
the different switches supported by mv88e6xxx have slightly different
register layout, we keep it simple and stupid by providing one dump
function per switch.
The remaining patches add support for the switch models currently
supported by the mv88e6xxx driver. Here's an example of dump of the
32 registers of a 88E6352 port:
# ethtool -d lan3
