tulip net driver updates:

* Add support for Conexant tulip clones.
* Do not store eeprom data on stack (128 or 512 bytes), it's a
large object, and also, we already have a copy in kmalloc'd RAM.

* tulip_core.c (tulip_init_one): Use tp->eeprom instead of
allocating a buffer for EEPROM copy on the stack.
* tulip_core.c: Add support for Conexant RS7112 (a.k.a. CN7112)
chip.
* tulip.h: Likewise. Increase EEPROM_SIZE to 512 bytes to
accomodate EEPROM on Conexant RS7112.

* tulip_core (tulip_pci_tbl[]):
