2008-09-15libertas: Reduce the WPA key installation time.Javier Cardona
WPA requires that the PTK is installed immediately after the 4-way handshake in order to properly decrypt the subsequent incoming EAPOL-GTK frame. If the PTK is not enabled by the time the EAPOL-GTK frame arrives, the frame is dropped and the supplicant does not receive the group key. This will happen with fast Access Points that send the EAPOL-GTK frame before the suplicant has successfully installed and enabled the PTK. To mitigate this situation, this patch simplifies and accelerates the SIOCSIWENCODEEXT execution.

2008-09-15libertas: remove unused generic RESET commandDan Williams
The generic reset command is unused. Each interface type needs to handle the reset command differently since after reset, the firmware is dead and interface-specific mechanisms must be used to reinitialize the card.

2008-09-11libertas: Improvements on automatic tx power control via SIOCSIWTXPOW.Anna Neal
iwconfig txpower can now be used to set tx power to fixed or auto. If set to auto the default firmware settings are used. The command CMD_802_11_PA_CFG is only sent to older firmware, as Dan Williams noted the command was no longer supported in firmware V9+.

2008-09-11libertas: clear current command on card removalDan Williams
If certain commands were in-flight when the card was pulled or the driver rmmod-ed, cleanup would block on the work queue stopping, but the work queue was in turn blocked on the current command being canceled, which didn't happen. Fix that. Signed-off-by: Dan Williams <dcbw@redhat.com> Cc: stable <stable@kernel.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2008-07-15mmc,sdio: helper function for transfer paddingPierre Ossman
There are a lot of crappy controllers out there that cannot handle all the request sizes that the MMC/SD/SDIO specifications require. In case the card driver can pad the data to overcome the problems, this commit adds a helper that calculates how much that padding should be. A corresponding helper is also added for SDIO, but it can also deal with all the complexities of splitting up a large transfer efficiently. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>

2008-06-17wext: Emit event stream entries correctly when compat.David S. Miller
Three major portions to this change: 1) Add IW_EV_COMPAT_LCP_LEN, IW_EV_COMPAT_POINT_OFF, and IW_EV_COMPAT_POINT_LEN helper defines. 2) Delete iw_stream_check_add_*(), they are unused. 3) Add iw_request_info argument to iwe_stream_add_*(), and use it to size the event and pointer lengths correctly depending upon whether IW_REQUEST_FLAG_COMPAT is set or not. 4) The mechanical transformations to the drivers and wireless stack bits to get the iw_request_info passed down into the routines modified in #3. Also, explicit references to IW_EV_LCP_LEN are replaced with iwe_stream_lcp_len(info). With a lot of help and bug fixes from Masakazu Mokuno. Signed-off-by: David S. Miller <davem@davemloft.net>

2008-06-09libertas: fix sleep confirmationHolger Schurig
This fixes an issus that made "iwconfig eth1 power on" non-working. When we get a "PS sleep" event, we have to confirm this to the firmware. The confirm happens with a command, but this command is special: the firmware won't send us a response. if_cs_host_to_card() is setting priv->dnld_sent anyway, so this variable stayed at DNLD_DATA_SENT and was never cleared back. Now I put the special knowledge that the CMD_802_11_PS_MODE with CMD_SUBCMD_SLEEP_CONFIRMED doesn't need to need a response by directly clearing the dnld_sent state in lbs_send_confirmsleep().
