2008-12-05tcp: fix tso_should_defer in 64bitIlpo Järvinen
Since jiffies is unsigned long, the types get expanded into that and after long enough time the difference will therefore always be > 1 (and that probably happens near boot as well as iirc the first jiffies wrap is scheduler close after boot to find out problems related to that early). This was originally noted by Bill Fink in Dec'07 but nobody never ended fixing it. Signed-off-by: Ilpo Järvinen <ilpo.jarvinen@helsinki.fi> Signed-off-by: David S. Miller <davem@davemloft.net>

tcp_minshall_update is not significant difference since it only checks for not full-sized skb which is BUG'ed on the push_one path anyway. tcp_snd_test is tcp_nagle_test+tcp_cwnd_test+tcp_snd_wnd_test, just the order changed slightly. net/ipv4/tcp_output.c: tcp_snd_test | -89 tcp_mss_split_point | -91 tcp_may_send_now | +53 tcp_cwnd_validate | -98 tso_fragment | -239 __tcp_push_pending_frames | -1340 tcp_push_one | -146 7 functions changed, 53 bytes added, 2003 bytes removed, diff: -1950 net/ipv4/tcp_output.c: tcp_write_xmit | +1772 1 function changed, 1772 bytes added, diff: +1772 tcp_output.o.new: 8 functions changed, 1825 bytes added, 2003 bytes removed, diff: -178 Signed-off-by: Ilpo Järvinen <ilpo.jarvinen@helsinki.fi> Signed-off-by: David S.

2008-12-05tcp: introduce struct tcp_sacktag_state to reduce arg pressureIlpo Järvinen
There are just too many args to some sacktag functions. This idea was first proposed by David S. Miller around a year ago, and the current situation is much worse that what it was back then. tcp_sacktag_one can be made a bit simpler by returning the new sacked (it can be achieved with a single variable though the previous code "caching" sacked into a local variable and therefore it is not exactly equal but the results will be the same). codiff on x86_64 tcp_sacktag_one | -15 tcp_shifted_skb | -50 tcp_match_skb_to_sack | -1 tcp_sacktag_walk | -64 tcp_sacktag_write_queue | -59 tcp_urg | +1 tcp_event_data_recv | -1 7 functions changed, 1 bytes added, 190 bytes removed, diff: -189 Signed-off-by: Ilpo Järvinen <ilpo.jarvinen@helsinki.fi> Signed-off-by: David S.

2008-12-05rt2x00: Move crypto TX descriptor handling to rt2x00crypto.cIvo van Doorn
Move all code which determines the right TX descriptor fields specific to crypto support into rt2x00crypto.c. This makes the code in rt2x00queue more simpler and better concentrates all crypto code into a single location. With this we can also remove some ifdefs in rt2x00queue.c since the code inside the ifdef is either very small, or only calling empty functions (see empty function definitions in rt2x00lib.h).

2008-12-05iwl3945 : Fix a-band association for passive channelsAbhijeet Kolekar
Patch does following things 1) This patch fixes the a-band association for passive channels with new uCode feature that it allows direct scan on passive channels after auto-switch from passive to active. This enables sending of direct probes on passive channels, as long as some traffic is detected on that channel. This improves the scanning for hidden SSIDs in A-band,which is all passive channels. This patch fixes the bug no 1748. http://www.intellinuxwireless.org/bugzilla/show_bug.cgi?id=1748 2) This fix will only work with uCode version 15.28.2.8 and above. Prior versions of uCode would work only if we heard the traffic within active dwell time, which is much shorter than passive dwell time and is shorter than typical beacon periods. This patch also provids full active dwell time even if we hear traffic late in passive dwell. 3) uCode API version is incremented to 2.

2008-12-05iwlwifi: rely on API version read from firmwareReinette Chatre
This adds the infrastructure to support older firmware APIs. The API version number is stored as part of the filename, we first try to load the most recent firmware and progressively try lower versions. The API version is also read from the firmware self and stored as part of the iwl_priv structure. Only firmware that is supported by driver will be loaded. The version number read from firmware is compared to supported versions in the driver not the API version used as part of filename. An example using this new infrastrucure: if (IWL_UCODE_API(priv->ucode_ver) >= 2) { Driver interacts with Firmware API version >= 2. } else { Driver interacts with Firmware API version 1. } Signed-off-by: Reinette Chatre <reinette.chatre@intel.com> Signed-off-by: John W.

2008-12-05iwlwifi: store ucode version numberChatre, Reinette

2008-12-05rt2x00: Optimize IV/EIV handlingIvo van Doorn
