There were a couple of attempts in the past to reduce it since it
took more than 1ms. Because mii_tick() periodically polls link
status, waiting more than 1ms for each GMII register access was
overkill. Unfortunately all previous attempts were failed with
various ways on different controllers.
This time, add additional 20us dealy at the end of GMII register
access which seems to requirement of all RealTek controllers to
issue next GMII register access request. This is the same way what
Linux does.

unreasonable to list all these controllers in one line description
of name. While I'm here mention that BCM590x/BCM5779x is Fast
Ethernet controller.
bge(4) still lacks support for some controllers but supporting
these controllers should be easy now and adding new controllers
do not require touching .Nd any more.

The IXP4XX platform can set interrupts on these pins for

The Cambria has the same interface but as all the pins are assigned to system
