2009-08-20b43: LP-PHY: Implement channel switching for rev0/1/B2062 radioGábor Stefanik
-Move pdiv from lpphy_2062_init to struct b43_phy_lp. -Add channel table for the B2062 radio. -Add code for tuning the B2062 radio to channel. -Add error handling to op_switch_channel, and use it for both radios. Rev0/1/B2062 will now hopefully show some signs of life, though it won't work at full performance, as calibration is still missing.

2009-08-20iwlwifi: fix erroneous use of iwl_rx_packet.len as a lengthDaniel C Halperin
The field called 'len' in struct iwl_rx_packet is in fact not just a length field but also includes some flags from the flow handler. In several places throughout the driver, this causes incorrect values to be interpreted as lengths when the field is improperly masked. In most situations the improper use is for debugging output, and simply results in an erroneous message, such as: [551933.070224] ieee80211 phy0: I iwl_rx_statistics Statistics notification received (480 vs -1367342620). which should read '(480 vs 484)'. In at least one case this could case bad things to happen: void iwl_rx_pm_debug_statistics_notif(struct iwl_priv *priv, struct iwl_rx_mem_buffer *rxb) { struct iwl_rx_packet *pkt = (struct iwl_rx_packet *)rxb->skb->data; IWL_DEBUG_RADIO(priv, "Dumping %d bytes of unhandled " "notification for %s:\n", le32_to_cpu(pkt->len), get_cmd_string(pkt->hdr.cmd)); iwl_print_hex_dump(priv, IWL_DL_RADIO, pkt->u.raw, le32_to_cpu(pkt->len) ); } EXPORT_SYMBOL(iwl_rx_pm_debug_statistics_notif); Given the rampant misuse of this field without proper masking throughout the driver (every use but one), this patch renames the field from 'len' to 'len_n_flags' to reduce confusion. It also adds the proper masking when this field is used as a length value.

2009-08-20iwlwifi: use station HT capabilities and BSS operating mode for Green-fieldDaniel C Halperin
Green-field mode should be configured in the HT station table. This patch uses both the per-station GF support flag as well as the current BSS HT operation mode (non-GF stations present flag). Added the "ht_greenfield_support" field to struct iwl_cfg to replace the device-specific check in rs_use_green(). That check has been moved to iwlcore_init_ht_hw_capab().

2009-08-20iwlwifi: check short GI support per-station rather than globallyDaniel C Halperin
Short guard interval support is a local per-station parameter not a global per-NIC parameter. (mac80211 will correctly remove SGI support from station capabilities if the BSS does not permit it). This patch removes the short GI support bitfield from the global iwl_ht_info struct and properly uses per-station HT capabilities during rate selection.

2009-08-20iwlwifi: configure HT40 channels in iwl_mac_configDaniel C Halperin
As indicated by note in iwl_ht_conf, some HT parameters are set on association (e.g., channel width) and some vary over time (HT protection mode) and per station (e.g., short GI support). The global parameters should be set in iwl_mac_config and the local/varying parameters in iwl_ht_conf. This patch moves the channel width configuration from iwl_ht_conf to iwl_mac_config, and defers further cleanup of the local/global conflation for a later patch. This fixes a bug in using HT40 channels in some modes. Signed-off-by: Daniel C Halperin <daniel.c.halperin@intel.com> Signed-off-by: Reinette Chatre <reinette.chatre@intel.com> Signed-off-by: John W.

2009-08-20iwlwifi: refactor packet reception codeDaniel C Halperin
This patch fixes a number of issues in iwl_rx_reply_rx and iwl_pass_packet_to_mac80211. These issues stem from the complexities of managing two different types of packet commands for different hardware. - Unify code handling rx_phy_res in SKB or cached to eliminate redundancy and remove potential NULL pointer accesses - Replace magic number with proper constant - Optimize functions by moving early exit conditions before computation - Comment code and improve some variable names - Remove redundant computation in iwl_pass_packet_to_mac80211 by passing in the correct, already-computed arguments.

2009-08-20iwlwifi: traverse linklist to find the valid OTP blockWey-Yi Guy
For devices using OTP memory, EEPROM image can start from any one of the OTP blocks. If shadow RAM is disabled, we need to traverse link list to find the last valid block, then start the EEPROM image reading. If OTP is not full, the valid block is the block _before_ the last block on the link list; the last block on the link list is the empty block ready for next OTP refresh/update. If OTP is full, then the last block is the valid block to be used for configure the device.

2009-08-20iwlwifi: prevent read outside array boundsReinette Chatre
With EDCA and HCCA we have 16 potential tid values. This is accommodated by mac80211, but iwlwifi only supports EDCA. With this implementation it is thus possible for mac80211 to request a tid that will cause iwlwifi to read outside array bounds. A similar problem exists if traffic is received in an unsupported category. We add error checking to catch these situations.

2009-08-14sky2: lock less transmit completionStephen Hemminger
Transmit completion can safely run lockless against transmit start. In the normal case, completion is done from NAPI and only looks at elements that are at the tail of the ring.
