Sam Leffler 5463c4a485 Overhaul monitor mode handling: 
o replace DLT_IEEE802_11 support in net80211 with DLT_IEEE802_11_RADIO
  and remove explicit bpf support from wireless drivers; drivers now
  use ieee80211_radiotap_attach to setup shared data structures that
  hold the radiotap header for each packet tx/rx
o remove rx timestamp from the rx path; it was used only by the tdma support
  for debugging and was mostly useless due to it being 32-bits and mostly
  unavailable
o track DLT_IEEE80211_RADIO bpf attachments and maintain per-vap and
  per-com state when there are active taps
o track the number of monitor mode vaps
o use bpf tap and monitor mode vap state to decide when to collect radiotap
  state and dispatch frames; drivers no longer explicitly directly check
  bpf state or use bpf calls to tap frames
o handle radiotap state updates on channel change in net80211; drivers
  should not do this (unless they bypass net80211 which is almost always
  a mistake)
o update various drivers to be more consistent/correct in handling radiotap
o update ral to include TSF in radiotap'd frames
o add promisc mode callback to wi

/*
* The WaveLAN/IEEE cards contain an 802.11 MAC controller which Lucent
* calls 'Hermes.' In typical fashion, getting documentation about this
* controller is about as easy as squeezing blood from a stone. Here
* is more or less what I know:
*
* - The Hermes controller is firmware driven, and the host interacts
* with the Hermes via a firmware interface, which can change.
*
* - The Hermes is described in a document called: "Hermes Firmware
* WaveLAN/IEEE Station Functions," document #010245, which of course
* Lucent will not release without an NDA.
*
* - Lucent has created a library called HCF (Hardware Control Functions)
* though which it wants developers to interact with the card. The HCF
* is needlessly complex, ill conceived and badly documented. Actually,
* the comments in the HCP code itself aren't bad, but the publically
* available manual that comes with it is awful, probably due largely to
* the fact that it has been emasculated in order to hide information
* that Lucent wants to keep proprietary. The purpose of the HCF seems
* to be to insulate the driver programmer from the Hermes itself so that
* Lucent has an excuse not to release programming in for it.
*
* - Lucent only makes available documentation and code for 'HCF Light'
* which is a stripped down version of HCF with certain features not
* implemented, most notably support for 802.11 frames.
*
* - The HCF code which I have seen blows goats. Whoever decided to
* use a 132 column format should be shot.
*
* Rather than actually use the Lucent HCF library, I have stripped all
* the useful information from it and used it to create a driver in the
* usual BSD form. Note: I don't want to hear anybody whining about the
* fact that the Lucent code is GPLed and mine isn't. I did not actually
* put any of Lucent's code in this driver: I only used it as a reference
* to obtain information about the underlying hardware. The Hermes
* programming interface is not GPLed, so bite me.
