The __UNCONST macro is now used only where necessary and the RW macros
are gone. Most of the changes here are consumers of the
sysctl_createv(9) interface that now takes a pair of const pointers
which used not to be.
Change the signature of IEEE80211_DPRINTF() so that it uses a bitmask, and
convert some of the if_printf()s to IEEE80211_DPRINTF()s. XXX I'm using a
global variable at the moment rather than per-interface.
net.link.ieee80211. The convention is that nodes directly under
net are protocol families (PF_*).
Also, simplify the sysctl setup for net80211 and rssadapt, following
another suggestion by Andrew.
independently from net80211 debug messages. Create a new sysctl,
net.ieee80211.rssadapt.debug, for turning the debug messages on
and off.
Create a new sysctl, net.ieee80211.rssadapt.expavgctl, to control
the rate of decay for the exponential averages used by rssadapt(9).
I have pulled that code into the function ieee80211_rssadapt_choose
so that I can re-use it in ath(4), atw(4), and in other drivers.
In rssadapt(9), I have also created a struct ieee80211_rssadapt_expavgctl
that contains parameters for rate adaptation. When IEEE80211_RSSADAPT_DEBUG
is enabled, I will using sysctl to expose an ieee80211_rssadapt_expavgctl
for each wireless device.
Also in rssadapt(9), I have introduced an interpolate() macro which
makes the exponential-averaging code more compact.
Adaptation Strategy for IEEE 802.11 WLAN via Received Signal Strength
Measurement" by Javier del Prado Pavon and Sunghyun Choi. This
module should provide faster adaptation and higher throughput than
Lucent's rate-adaptation scheme.
Individual drivers need to be modified to use this module. Patches
for wi(4) are forthcoming.
