263bbda93d wtap should check if ieee80211_vap_setup fails. 
* If ieee80211_vap_setup fails, we free allocated M_80211_VAP
  memory and return NULL;

3c6b71699a wtap: fix clang warning. 
* The warning message was:
    'warning error: format string is not a string literal';
* Changed how make_dev is called, now a string literal
  for formatting is used;

a574db0838 Fix wtap to not panic in wtap_beacon_intrp. 
* Changed KASSERT to be debug printf (DWTAP_PRINTF). If state is not
IEEE80211_S_RUN we return without scheduling a new callout;
* When net80211 stack changes state to IEEE802_11_INIT we stop the
beacon callout task;

b850e3b883 Remove this - it's not needed as it's defined in ieee80211_freebsd.h. 2012-03-19 13:54:15 +00:00

7870adb640 Remove direct access to si_name. 
Code should just use the devtoname() function to obtain the name of a
character device. Also add const keywords to pieces of code that need it
to build properly.

04d1980289 Introduce wtap, the beginnings of a net80211 wlan simulator. 
This introduces:

* a basic wtap interface
* a HAL, which implements an abstraction layer for implementing
  different device behavious;
* A visibility plugin, which allows for control over which nodes
  see other nodes (useful for mesh work.)

It doesn't yet implement sta/adhoc/hostap modes but these are quite
feasible to implement.

Monthadar uses it to do 802.11s mesh verification.

The userland tools will be committed in a follow-up commit.
