using miibus, since for some devices that use multiple addresses on the bus,
going through miibus may be unclear, and for devices that are not standard
MII PHYs, miibus may throw a fit, necessitating complicated interfaces to
fake the interface that it expects during probe/attach.
o) Make the mv88e61xx SMI interface in octe attach a PHY directly and fix some
mistakes in the code that resulted from trying too hard to present a nice
interface to miibus.
o) Add a PHY driver for the mv88e61xx. If attached (it is optional in kernel
compiles so the default behavior of having a dumb switch is preserved) it
will place the switch in a VLAN-tagging mode such that each physical port
has a VLAN associated with it and interfaces for the VLANs can be created to
address or bridge between them.
XXX It would be nice for this to be part of a single module including the
SMI interface, and for it to fit into a generic switch configuration
framework and for it to use DSA rather than VLANs, but this is a start
and gives some sense of the parameters of such frameworks that are not
currently present in FreeBSD. In lieu of a switch configuration
interface, per-port media status and VLAN settings are in a sysctl tree.
XXX There may be some minor nits remaining in the handling of broadcast,
multicast and unknown destination traffic. It would also be nice to go
through and replace the few remaining magic numbers with macros at some
point in the future.
XXX This has only been tested with the MV88E6161, but it should work with
minimal or no modification on related switches, so support for probing
them was included.
Thanks to Pat Saavedra of TELoIP and Rafal Jaworowski of Semihalf for their
assistance in understanding the switch chipset.
