- Added address conflict check during attach.
- Fixed loopback processing to correctly handle forward packets.
- Fixed interrupt dispatch issue which caused delivered packets
(in and out) to sometimes not interrupt the CPU after processing.

ROM mac address, even after it is changed by SET XQ MAC=.
- Added changes so that the Console DELQA diagnostic (>>>TEST 82)
will succeed.
- Added DELQA-T (aka DELQA Plus) device emulation support.
- Added dropped frame statistics to record when the receiver discards
received packets due to the receiver being disabled, or due to the
XQ device's packet receive queue being full.
- Fixed bug in receive processing when we're not polling. This could
cause receive processing to never be activated again if we don't
read all available packets via eth_read each time we get the
opportunity.
- Added the ability to Coalesce received packet interrupts. This
is enabled by SET XQ POLL=DELAY=nnn where nnn is a number of
microseconds to delay the triggering of an interrupt when a packet
is received.
- Added SET XQ POLL=DISABLE (aka SET XQ POLL=0) to operate without
polling for packet read completion.
- Changed the sanity and id timer mechanisms to use a separate timer
unit so that transmit and recieve activities can be dealt with
by the normal xq_svc routine.
Dynamically determine the timer polling rate based on the
calibrated tmr_poll and clk_tps values of the simulator.
- Enabled the SET XQ POLL to be meaningful if the simulator currently
doesn't support idling.
- Changed xq_debug_setup to use sim_debug instead of printf so that
all debug output goes to the same place.
- Restored the call to xq_svc after all successful calls to eth_write
to allow receive processing to happen before the next event
service time. This must have been inadvertently commented out
while other things were being tested.
