NICs. (Finally!) The PCMCIA, ISA and PCI varieties are all supported, though only the ISA and PCI ones will work on the alpha for now. PCCARD, ISA and PCI attachments are all provided. Also provided an ancontrol(8) utility for configuring the NIC, man pages, and updated pccard.conf.sample. ISA cards are supported in both ISA PnP and hard-wired mode, although you must configure the kernel explicitly to support the hardwired mode since you have to know the I/O address and port ahead of time. Special thanks to Doug Ambrisko for doing the initial newbus hackery and getting it to work in infrastructure mode.
