CVS commit: src/sys/dev/ic

[David Young <dyoung%netbsd.org@localhost>]

Module Name:    src
Committed By:   dyoung
Date:           Fri Nov 16 23:35:20 UTC 2007

Modified Files:
        src/sys/dev/ic: rtw.c rtwreg.h rtwvar.h

Log Message:
Accommodate the variety of RF front-ends when radiotapping frames:
tap only RSSI when there is a Philips RF front-end.  Tap both Barker
lock quality and RSSI when there is any other RF front-end.

Provide radiotap listeners a more complete picture of channel
activity:

    in promiscuous mode, tap frames who do not pass the CRC32 check.
    Flag packets that were received with a short preamble.  Ask
    the NIC to pass us 802.11 Control frames.  Pass frames to
    radiotap listeners before stripping the FCS.  Re-order operations
    in rtw_intr_rx() in order to accomplish all of this, taking
    care not to pass a broken packet to net80211!

Do not provide a flags field when tapping xmitted frames.

Assert sane Rx packet lengths.  Really should check and drop instead
of KASSERTing.  I will revisit this, soon.
