Subject: drivers: remove redundant PCI ID tables
X-Git-Tag: v3.2.1~672
X-Git-Url: http://zhaoyanbai.com/repos/%22http:/www.isc.org/icons/zpipe.c?a=commitdiff_plain;h=5152cfd8bd6bf1de667379a59912a97a9b2cf7a8;p=minix.git

drivers: remove redundant PCI ID tables
- remove PCI tables where system.conf suffices
- remove drivers' ability to mess up NIC order
- fix dp8390 PCI enumeration
- convert ti1225 to instance model
- add system.conf entry for ti1225
