* Make Ethernet autonegotiation on INCA-IP work for all clock rates;

  allow selection of clock frequency as "make" target

* Implement memory autosizing code for IceCube boards

* Configure network port on INCA-IP for autonegotiation

* Fix overflow problem in network timeout code

* Patch by Richard Woodruff, 8 Aug 2003:
  Allow crc32 to be used at address 0x000 (crc32_no_comp, too).
