- alignment problem with 1.3.* kernel and some minor changes.
Thomas Bogendoerfer (tsbogend@bigbug.franken.de):
- added support for Linux/Alpha, but removed most of it, because
- it worked only for the PCI chip.
+ it worked only for the PCI chip.
- added hook for the 32bit lance driver
- added PCnetPCI II (79C970A) to chip table
Paul Gortmaker (gpg109@rsphy1.anu.edu.au):
before unregister_netdev() which caused NULL pointer
reference later in the chain (in rtnetlink_fill_ifinfo())

Forward ported v1.14 to 2.1.129, merged the PCI and misc changes from
the 2.1 version of the old driver - Alan Cox
