Modification history:
03-Mar-08 MP Added DELQA-T (aka DELQA Plus) device emulation support.
06-Feb-08 MP 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. Also removed the
filter statistic counter since there was no code which ever set it.
29-Jan-08 MP Dynamically determine the timer polling rate based on the
calibrated tmr_poll and clk_tps values of the simulator.
23-Jan-08 MP Added debugging support to display packet headers and packet data
07-Jul-05 RMS Removed extraneous externs
20-Jan-04 DTH Added new sanity timer and system id timer
19-Jan-04 DTH Added XQ_SERVICE_INTERVAL, poll
09-Jan-04 DTH Added Boot PDP diagnostic definition, XI/RI combination
26-Dec-03 DTH Moved ethernet queue definitions to sim_ether
25-Nov-03 DTH Added interrupt request flag
02-Jun-03 DTH Added struct xq_stats
28-May-03 DTH Made xq_msg_que.item dynamic
28-May-03 MP Optimized structures, removed rtime variable
06-May-03 DTH Changed 32-bit t_addr to uint32 for v3.0
28-Apr-03 DTH Added callbacks for multicontroller identification
25-Mar-03 DTH Removed bootrom field - no longer needed; Updated copyright
15-Jan-03 DTH Merged Mark Pizzolato's changes into main source
13-Jan-03 MP Added countdown for System Id multicast packets
10-Jan-03 DTH Added bootrom field
30-Dec-02 DTH Added setup valid field
21-Oct-02 DTH Corrected copyright again
15-Oct-02 DTH Fixed copyright, added sanity timer support
10-Oct-02 DTH Added more setup fields and bitmasks
08-Oct-02 DTH Integrated with 2.10-0p4, added variable vector and copyrights
03-Oct-02 DTH Beta version of xq/sim_ether released for SIMH 2.09-11
15-Aug-02 DTH Started XQ simulation
