* ipv6 fib: Use "Sweezle" to optimize addr_bit_test().YOSHIFUJI Hideaki / 吉藤英明2010-03-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | addr_bit_test() is used in various places in IPv6 routing table subsystem. It checks if the given fn_bit is set, where fn_bit counts bits from MSB in words in network-order. fn_bit : 0 .... 31 32 .... 64 65 .... 95 96 ....127 fn_bit >> 5 gives offset of word, and (~fn_bit & 0x1f) gives count from LSB in the network-endian word in question. fn_bit >> 5 : 0 1 2 3 ~fn_bit & 0x1f: 31 .... 0 31 .... 0 31 .... 0 31 .... 0 Thus, the mask was generated as htonl(1 << (~fn_bit & 0x1f)). This can be optimized by "sweezle" (See include/asm-generic/bitops/le.h). In little-endian, htonl(1 << bit) = 1 << (bit ^ BITOP_BE32_SWIZZLE) where BITOP_BE32_SWIZZLE is (0x1f & ~7) So, htonl(1 << (~fn_bit & 0x1f)) = 1 << ((~fn_bit & 0x1f) ^ (0x1f & ~7)) = 1 << ((~fn_bit ^ ~7) & 0x1f) = 1 << ((~fn_bit ^ BITOP_BE32_SWIZZLE) & 0x1f) In big-endian, BITOP_BE32_SWIZZLE is equal to 0. 1 << ((~fn_bit ^ BITOP_BE32_SWIZZLE) & 0x1f) = 1 << ((~fn_bit) & 0x1f) = htonl(1 << (~fn_bit & 0x1f)) Signed-off-by: YOSHIFUJI Hideaki <yoshfuji@linux-ipv6.org> Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support for basic configuration of a connection quality monitoring to the nl80211 interface, and basic support for notifying about triggered monitoring events. Via this interface a user-space connection manager may configure and receive pre-warning events of deteriorating WLAN connection quality, and start preparing for roaming in advance, before the connection is already lost. An example usage of such a trigger is starting scanning for nearby AP's in an attempt to find one with better connection quality, and associate to it before the connection characteristics of the existing connection become too bad or the association is even lost, leading in a prolonged delay in connectivity. The interface currently supports only RSSI, but it could be later extended to include other parameters, such as signal-to-noise ratio, if need for that arises.

| * mac80211: Add support for connection monitor in hardwareJuuso Oikarinen2010-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch is based on a RFC patch by Kalle Valo. The wl1271 has a feature which handles the connection monitor logic in hardware, basically sending periodically nullfunc frames and reporting to the host if AP is lost, after attempting to recover by sending probe-requests to the AP. Add support to mac80211 by adding a new flag IEEE80211_HW_CONNECTION_MONITOR which prevents conn_mon_timer from triggering during idle periods, and prevents sending probe-requests to the AP if beacon-loss is indicated by the hardware.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I discovered that if EMBEDDED=y, one can accidentally build a mac80211 stack and drivers w/ no rate control algorithm. For drivers like RTL8187 that don't supply their own RC algorithms, this will cause ieee80211_register_hw to fail (making the driver unusable). This will tell kconfig to provide a warning if no rate control algorithms have been selected. That'll at least warn the user; users that know that their drivers supply a rate control algorithm can safely ignore the warning, and those who don't know (or who expect to be using multiple drivers) can select a default RC algorithm.

However, in some situations (e.g. no traffic) it would be nicer to scan a few channels in a row to speed up the scan itself. Hence, after scanning a channel, check if we have queued up any tx frames and return to the operating channel in that case. Unfortunately we don't know if the AP has buffered any frames for us. Hence, scan only as many channels in a row as the pm_qos latency and the negotiated listen interval allows us to. Signed-off-by: Helmut Schaa <helmut.schaa@googlemail.com> Signed-off-by: John W.
