* iwlegacy: use pci_dev->revisionSergei Shtylyov2011-04-19
| | | | | | | | | | Commit be663ab67077fac8e23eb8e231a8c1c94cb32e54 (iwlwifi: split the drivers for agn and legacy devices 3945/4965) added code to read the 4965's revision ID from the PCI configuration register while it's already stored by PCI subsystem in the 'revision' field of 'struct pci_dev'...

* iwl4965: drop a lone pr_err()Paul Bolle2011-04-12
| | | | | | | | | | iwl4965_rate_control_register() prints a message at KERN_ERR level. It looks like it's just a debugging message, so pr_err() seems to be overdone. But none of the similar functions in drivers/net/wireless print a message, so let's just drop it. Signed-off-by: Paul Bolle <pebolle@tiscali.nl> Signed-off-by: John W.

* iwlegacy: fix bugs in change_interfaceJohannes Berg2011-03-29
| | | | | | | | | | | | | If change_interface gets invoked during a firmware restart, it may crash; prevent that from happening by checking if ctx->vif is assigned. Additionally, in my initial commit I forgot to set the vif->p2p variable correctly, so fix that too.

* iwl3945: disable hw scan by defaultStanislaw Gruszka2011-03-29
| | | | | | | | | | | | | | | | | | | After new NetworkManager 0.8.996 changes, hardware scanning is causing microcode errors as reported here: https://bugzilla.redhat.com/show_bug.cgi?id=683571 and sometimes kernel crashes: https://bugzilla.redhat.com/show_bug.cgi?id=688252 Also with hw scan there are very bad performance on some systems as reported here: https://bugzilla.redhat.com/show_bug.cgi?id=671366 Since Intel no longer supports 3945, there is no chance to get proper firmware fixes, we need workaround problems by disable hardware scanning by default.

* iwlwifi: remove duplicate initializationDan Carpenter2011-02-28
| | | | | | | | | | | rate_mask is initialized again later so this can be removed. Btw, if rate_control_send_low(sta, priv_sta, txrc) returns false, that means that "sta" is non-NULL. That's why the second initialization of rate_mask is a little simpler than the first.

* mac80211: make tx() operation return voidJohannes Berg2011-02-25
| | | | | | | | | | | | | | | | | | | | | | The return value of the tx operation is commonly misused by drivers, leading to errors. All drivers will drop frames if they fail to TX the frame, and they must also properly manage the queues (if they didn't, mac80211 would already warn). Removing the ability for drivers to return a BUSY value also allows significant cleanups of the TX TX handling code in mac80211. Note that this also fixes a bug in ath9k_htc, the old "return -1" there was wrong.

* iwlwifi: split the drivers for agn and legacy devices 3945/4965Wey-Yi Guy2011-02-21
Intel WiFi devices 3945 and 4965 now have their own driver in the folder drivers/net/wireless/iwlegacy Add support to build these drivers independently of the driver for AGN devices. Selecting the 3945 builds iwl3945.ko and iwl_legacy.ko, and selecting the 4965 builds iwl4965.ko and iwl_legacy.ko. iwl-legacy.ko contains code shared between both devices. The 3945 is an ABG/BG device, with no support for 802.11n. The 4965 is a 2x3 ABGN device.
