9 years agopktgen: spin using hrtimer
Stephen Hemminger [Sat, 29 Aug 2009 06:41:29 +0000]
pktgen: spin using hrtimer

This changes how the pktgen thread spins/waits between
packets if delay is configured. It uses a high res timer to
wait for time to arrive.

ath5k: fix uninitialized value use in ath5k_eeprom_read_turbo_modes()

The `val' variable in ath5k_eeprom_read_turbo_modes() is used
uninitialized.  gcc 4.4.1 with -fno-inline-functions-called-once reports
it:

eeprom.c: In function 'ath5k_eeprom_read_turbo_modes':
eeprom.c:441: warning: 'val' may be used uninitialized in this function

Comparing the code to the Atheros HAL, it's clear that the split between
ath5k_eeprom_read_modes() and ath5k_eeprom_read_turbo_modes() was
incorrect.

The Atheros HAL reads both turbo and non-turbo data from EEPROM in one
function.  Some turbo mode parameters are derived from the same EEPROM
values as non-turbo parameters, just from different bits.

Merge ath5k_eeprom_read_turbo_modes() into ath5k_eeprom_read_modes() to
fix the warning.  The actual values and offsets have been cross-checked
against Atheros HAL.

iwlwifi: fix ICT irq table endianness

The ICT IRQ table is a set of __le32 values, not u32 values,
so when reading it we need to take into account that it has
to be converted to CPU endianness. This was causing a lot of
trouble on my powerpc box where various things would simply
not work for no apparent reason with 5xxx cards, but worked
with 4965 -- which doesn't use the ICT table.

-Fix a few nasty typos (b43_phy_* operations instead of b43_radio_*)

-Fix some typos & spec errors found by MMIO tracing.
-Optimize b43_phy_write & b43_phy_mask/set/maskset to use
 only the minimal number of MMIO accesses. (Write is possible
 using a single 32-bit MMIO write, while set/mask/maskset can

-Set the default channel back to 1, as the bug forcing us to use
 channel 7 is now fixed.

With this, the device comes up, scans, associates, transmits,

it's fully functional. Sensitivity and TX power are still sub-optimal,

accordingly.

The information is provided per SISO (a,b,c) chain based, it also has

iwlwifi: Make injection of non-broadcast frames work again

Commit 1ccb84d87d04df3c76cd4352fe69786d8c7cf016 by Wey-Yi Guy
("iwlwifi: clean up unused NL80211_IFTYPE_MONITOR for Monitor mode")
broke injection of non-broadcast frames to unassociated stations
(causing a SYSASSERT for all such injected frames), due to injected
frames no longer automatically getting a broadcast station ID assigned.
This patch restores the old behavior, fixing the aforementioned
regression.

Also, consistently check for IEEE80211_TX_CTL_INJECTED instead of
iwl_is_monitor_mode in the TX path, as TX_CTL_INJECTED specifically
means that a given packet is coming from a monitor interface, while
iwl_is_monitor_mode only shows whether a monitor interface exists
on the device.

libertas: Add support for Marvell Libertas CF8305

The CF8305 is a very old silicon running firmware version 3.0 . This card also
needs some special treatment as it's so old it can't do unaligned register
access. But since that happens only at one place, there were no changes made to
the register access functions, but instead that particular place was fixed.
Also, this card uses only one-stage firmware which is loaded the same way as
helper firmware. The second-stage firmware isn't loaded on this card and doesn't
therefore have to be supplied.
