15 years ago- Import driver[acx(4)] for TI acx100/acx111 based WiFi NIC.

- Import driver[acx(4)] for TI acx100/acx111 based WiFi NIC.
- Import user space utility[acxcontrol(8)] to load firmware and show driver
- Add acx(4) and acxcontrol(8) man pages.
- Build acx(4) as module only, since it needs firmware to work.
- Add an entry for acx(4) in LINT.

This driver is known to work with following hardware:
D-Link DWL-520+
D-Link DWL-650+
D-Link DWL-G520+
D-Link DWL-G650+

work well in adhoc mode.  PBCC based rate, 22Mbits/s, is not supported yet.

acxcontrl(8) and man pages are written by Sascha Wildner.  He also kindly
helped debugging and testing the driver.  Thank you, Sascha!

The meaning and layout of hardware registers are based on the reverse
engineering work done by people at acx100.sourceforge.net
