mycroft 1989546a4c GC unused stuff. 2004-12-27 05:36:08 +00:00
mycroft 06e4fe7f62 Replace d_plcp_svc with d_residue. The latter is the number of whole 
empty/unused octets to fill out the data time slot.  The value is constrained
by math to 0 for <= 5.5Mb, 0-1 for 11Mb, and 0-2 for 22Mb.  It is used to
signal to the MAC that there is residue.

dyoung 8828aae46c #define the difference in microseconds between a fast and a slow 
preamble and PLCP header.

dyoung 81eefc6f1a Define for more bits in the Service field of the 802.11 PLCP Header. 
For use by the subroutine ieee80211_compute_duration, add struct
ieee80211_duration, and #define a number of microsecond constants
used for the transmit timing of 802.11 packets.

Add the subroutine ieee80211_compute_duration, which computes for
any packet the appropriate 802.11 Duration field, the PLCP Length
field, as well as the Duration and Length fields for an RTS frame.

atw(4), rtw(4), future drivers, and possibly ath(4) will share
ieee80211_compute_duration.

dyoung bf30017770 From FreeBSD. Definite structures and constants for 
QoS/WME/802.11e, for WPA, and for 802.11 MTU.

dyoung 9280f4b428 Synchronize with FreeBSD sources from 12 Dec 2003. 2003-12-14 09:56:53 +00:00
dyoung db0e43b296 Add WEP shared-key authentication. 2003-10-15 11:43:51 +00:00
dyoung 8a3890c655 More changes to the new 802.11 layer: 
* Add Kevin Lahey's power-saving support from the old 802.11 layer

* Support for frequency-hopping PHYs

    * Add support frequency-hopping PHY mode, IFM_IEEE80211_FH
    * Add channel flags for frequency-hopping
    * Add mode<->media mappings in for FH PHY in ieee80211_media2rate
      and ieee80211_rate2media

* Stop using IFM_MAKEMODE macro since the mode constants
  (e.g., IFM_IEEE80211_11A) are pre-shifted in sys/net/if_media.h

* Add some PLCP constants.

dyoung 40e261aa72 Pull in net80211/ from FreeBSD. This contains Sam Leffler's 
enhancements to the 802.11 layer, which are necessary for ath(4),
the Atheros-chipset driver.
