2008-10-31iwlwifi: Update reclaim flagDaniel Halperin
The reclaim flag should include REPLY_RX_MPDU_CMD in the list of commands issued by uCode. This is for safety in case the SEQ_RX_FRAME bit is set incorrectly.

2008-10-31iwl3945: iwl3945_mac_get_tsf() should not return zeroFabrice Bellet
The problem fixed here is that iwl3945_mac_get_tsf() returns 0, as the function is not implemented, and this is considered as a valid value by the mac layer in mlme.c:1605. The consequence is that the STA in ad-hoc mode is inserted/removed quite frequently due to IBSS merging.

2008-10-31iwlwifi: clear scanning bits upon failureMohamed Abbas
In iwl_bg_request_scan function, if we could not send a scan command it will go to done.

2008-10-31airo: Kill directly reference of netdev->privWang Chen
We have some reasons to kill netdev->priv: 1. netdev->priv is equal to netdev_priv(). 2. netdev_priv() wraps the calculation of netdev->priv's offset, obviously netdev_priv() is more flexible than netdev->priv. But we cann't kill netdev->priv, because so many drivers reference to it directly. OK, becasue Dave S. Miller said, "every direct netdev->priv usage is a bug", and I want to kill netdev->priv later, I decided to convert all the direct reference of netdev->priv first. In this driver, I don't simply use netdev_priv() to replace netdev->priv. The reason is: Pointer netdev->priv was changed in this driver, but it shouldn't. Because the memory was allocated when alloc_netdev() and netdev->priv should always point to that memory. So I use netdev->ml_priv to replace netdev->priv. After replacing, both ai and ai->wifidev->ml_priv point to the same memory. Signed-off-by: Wang Chen <wangchen@cn.fujitsu.com> Cc: John W.

2008-10-31rtl8187: add short slot handling for 8187BHerton Ronaldo Krzesinski
This change adds short slot handling for 8187B variant of rtl8187 chips. Some things to note about changes done: * Values used are chosen to met 802.11-2007 spec. This raised a question about SIFS value used with 8187L: 0x22 (34) doesn't match any spec value. For now just don't change 8187L, but is something to be looked at. * On 8187B, the location of EIFS register is at the same place as BRSR+1 of struct rtl818x_csr. Unfortunately there is no clean way to accomodate 8187B differences currently, just use address of BRSR+1 and comment about it. The same thing happens for Ack timeout register, that is on CARRIER_SENSE_COUNTER location of 8187L. The eifs and ack timeout values are in units of 4us. All these registers information was gathered from references being the vendor gpl driver and 8180 datasheet, unfortunately there is no information about this on 8187B datasheet. Also the ack timeout value was inspired by the same calculation as done on rt2x00. Signed-off-by: Herton Ronaldo Krzesinski <herton@mandriva.com.br> Signed-off-by: John W.
