[src-draft/trunk]: src/sys/dev/pci Function paramaters re written to use vap.
details: https://anonhg.NetBSD.org/src-all/rev/054719a2dac5
branches: trunk

description:
Function paramaters re written to use vap.
Improved rx_done handling from urtwn.
Let state machine control scanning.
No functions except for newstate_cb override newstate callback.
iwn can now scan!
