Log Message:
Move the register access mode into struct rtw_regs.  Change
rtw_set_access, rtw_set_access1 to match.

Add a subroutine for setting WEP keys.  WEP isn't quite finished,
because I have to add the WEP header to Tx packets.  Implement the
SIOCS80211NWKEY ioctl for setting WEP keys.

Program the LEDs based on operating state and packet activity.

 * On a Revision F RTL8180, blink LED1 at 1Hz to indicate
   scan/authenticate/associate states.  In the run state, turn LED1
   on.  In every state, blink LED1 at 5Hz to indicate non-beacon
   tx/rx activity.  I would like to use two LEDs, but in all my
   Rev. F instances, LED0 is not wired to an LED; instead, the
   first LED is wired to indicate that the card's power is on.

 * On a Revision D RTL8180, program the LEDs so that LED0 indicates
   Tx, and LED1 indicates Rx.  The Rx LED will blink annoyingly if
   there are beacons in the air, but at least the Tx LED is useful.

 * Store the hardware revision in the softc to support my futile
   attempt at programming LEDs for both Rev. D and Rev. F parts;
   I never did get Rev. D LEDs to work right.

 * Add a debug flag RTW_DEBUG_LED for the LED transitions.

Add RTW_TPPOLL_ALL, RTW_TPPOLL_SALL to start and stop, respectively,
all of the transmit rings.

In ad hoc mode, allocate a beacon and load it into the beacon ring.
Start the ring.  In one trial, the card re-transmitted the beacon
ring's contents several times before stopping.  More programming
and testing for ad hoc mode is necessary.  I'm not setting the
beacon flag in the transmit descriptor.

Revamp the transmit section to make better use of all the transmit
rings:  beacon queue, high-, low-, and medium-priority rings.  Put
beacon frames on the beacon ring.  All other management frames,
and data frames, go on the medium-priority ring.  Power-save data
frames go on the high-priority ring.  (Note that powersaving is
not implemented!)  This is a work in progress.

Send all 802.11 Management frames at 1Mbps.

After we put a packet on a transmit ring, tickle the right bit in
the TPPOLL to tell RTL8180.  Stop all rings on error and in rtw_stop.

Use the RF chip type, not the RTL8180 revision, to choose between
host- and MAC-controlled RF serial I/O.  Now the Netgear MA521
works.

Remove bogus definition of bit RTW_TPPOLL_FSWINT.
