- Don't request BUS_DMA_ALLOCNOW for dma tags, that requires enormous
amount of memory.
- Don't request segsize of BUS_SPACE_MAXSIZE_32BIT, when maxsize is
MCLBYTES.

With this change bwi_attach() can succeed on i386.

MFC r280347: Remove MAXBSIZE use from drivers where it has nothing to do.

2015-04-21T11:27:50+00:00

In some cases limits are just not needed, in others -- DFLTPHYS is the
right constant to use instead.

MFC r260444:

2014-02-17T01:36:53+00:00

Rename definition of IEEE80211_FC1_WEP to IEEE80211_FC1_PROTECTED.

The origin of WEP comes from IEEE Std 802.11-1997 where it defines
whether the frame body of MAC frame has been encrypted using WEP
algorithm or not.
IEEE Std. 802.11-2007 changes WEP to Protected Frame, indicates
whether the frame is protected by a cryptographic encapsulation
algorithm.

ieee80211_rate2plcp() and ieee80211_rate2phytype() are both pre-11n

2013-08-13T09:58:27+00:00

routines and thus assert if one passes in a rate code with the
high bit set.

Since the high bit can indicate either IEEE80211_RATE_BASIC or
IEEE80211_RATE_MCS, it's up to the caller to determine whether
the rate is 11n or not, and either mask out the BASIC bit, or
call a different function.

(Yes, this does mean that net80211 should grow 11n-aware rate2phytype()
and rate2plcp() functions..)

This may need to happen for the other drivers - it's currently only
done (now) for iwn(4) and bwi(4).

Fix some net80211 enum nits:

2011-12-17T10:23:17+00:00

- ic_vap_create() uses an ieee80211_opmode argument
- ieee80211_rate2media() takes an ieee80211_phymode argument
- ieee80211_plcp2rate() takes an ieee80211_phytype argument
- cast to enum ieee80211_protmode and ieee80211_roamingmode to silence
  compiler warnings
