wireless NICs need the host's help to fragment packets before the
NIC transmits them. From Sam Leffler.
Screen-scraped by me from the WWW source browser at perforce.freebsd.org.
alignment. This
1 helps GCC make better code for architectures such as ARM
where it would otherwise do a lot of byte-loads and shifts
to load a multi-byte word, and
2 ensures that the compiler will add no padding between a
radiotap header and a 64-bit or narrower field that
follows it.
[correct would have been howmany(...), use IEEE80211_CHAN_BYTES,
which is used in the other ioctl method. While here s/u_char/u_int8_t/
for chanlist to match the rest of the uses.
ic->ic_bss, but it uses the rateset in its new ieee80211_node
argument, instead. If the rate is fixed by ic->ic_fixed_rate, but
the fixed rate is not in the node's rateset, choose a reasonable
default: prefer the lowest basic rate or, if there is no basic
rate, prefer the lowest rate, period.
Change a printf complaint to a debug message.
Adapt drivers to suit new ieee80211_get_rate calling convention.
XXX I really need to replace ieee80211_get_rate with a bitrate
XXX adaptation algorithm. Soon, soon....
sam@ and various open source repositories:
ath(4):
Ignore "phantom" beacon misses: should stabilize connections
to access points (no more ceaseless link-UP/DOWN indications).
Also, re-synchronize beacon timer using the TSF in the
first beacon received after joining a BSS---this should
also help suppress spurious beacon misses. I am hopeful
that this will help ath(4) lossage reported by perry@ and
smb@.
Add new configuration through sysctl.
Use a shorter calibration interval until IQ calibration
finishes.
Report antenna noise through radiotap.
Rudiments of Radar Detection / Dynamic Frequency Selection.
Update to HAL version 0.9.16.13.
Update open sources for changes to the HAL API.
Add HALs for additional architectures: add big-endian ELF
HALs for sparc64 and for PowerPC. Also add a Alpha HAL.
These new HALs are untested under NetBSD.
ath(4) + net80211:
Make the multicast transmit rate configurable by ioctl.
Miscellaneous bug fixes.
set the mgt frame tx timer before dispatching the frame to the
driver; this closes a race where a response could be processed
before the timer was started and cause a RUN->SCAN state change
when operating in station mode
lenght calculation phase instead of just growing the buffer like the older
patch did. I am leaving the bigger buffer too for now since it does not hurt.
Change -1 to named constant IEEE80211_FIXED_RATE_NONE. ic_fixed_rate
is an index into the ic_sup_rates table, so lookup a fixed rate
there and search the ni->ni_rates table for it.
Duration and PLCP Length fields, and delete the abominable
atw_frame_setdurs() subroutine.
Make rtw(4) use the new ieee80211_compute_duration() calling
convention.
Add an ieee80211_key argument to ieee80211_compute_duration() and
lightly constify arguments. Get the crypto header length from the
key argument instead of blithely assuming a WEP header. Add some
inline documentation. Account for data padding (IEEE80211_F_DATAPAD).
ieee80211_recv_mgmt(). ieee80211_update_adhoc_node() updates IBSS
nodes based on received beacons and probe responses. I extract a
subroutine to maintain a tolerable indentation level.
