drochner 2fc45929e2 some cleanup/fixes: 
-get boot messages to NetBSD's standards (ie at least 3 lines)
-get some card information from PCI ID and subsystem ID
-fix media handling and link reporting for fiber cards
-port cksum offloading to NetBSD and enable as far as appropriate
 (TCP/UDP transmit offloading still disabled, as in OpenBSD)
