| | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit bada339ba24dee9e143bfb42e1dc61f146619846 enforces that all interfaces have a valid MAC address before they are brought up. ipw2200 does not assign a MAC address to it's radiotap interface, meaning that the radiotap interface cannot be brought up in 2.6.24. https://bugs.gentoo.org/show_bug.cgi?id=215714 Fix this by copying the MAC address from the real interface.

* | [NET]: Undo code bloat in hot paths due to print_mac().David S. Miller2008-04-08
|/ | | | | | | | | | | | | | | | | If print_mac() is used inside of a pr_debug() the compiler can't see that the call is redundant so still performs it even of pr_debug() ends up being a nop. So don't use print_mac() in such cases in hot code paths, use MAC_FMT et al. instead. As noted by Joe Perches, pr_debug() could be modified to handle this better, but that is a change to an interface used by the entire kernel and thus needs to be validated carefully. This here is thus the less risky fix for 2.6.25 Signed-off-by: David S. Miller <davem@davemloft.net>

* rt2x00: Ignore set_state(STATE_SLEEP) failureIvo van Doorn2008-03-27
| | | | | | | | | | | | | | Some hardware never seem to accept the "goto sleep" command, since the legacy drivers don't have suspend and resume handlers the entire code for it was basically a educated guess (based on the "enable radio" code). This patch will only print a warning when the "goto sleep" command fails, and just continues as usual. Perhaps that means the device will not reach a sleep state and consumes more power then it should, but it is equally possible it simply needs some seconds longer to sleep. Anyway, by making the command non-fatal it will not block the rest of the suspend procedure. Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* drivers/net/wireless/iwlwifi/iwl-4965.c: correct use of ! and &Julia Lawall2008-03-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In commit e6bafba5b4765a5a252f1b8d31cbf6d2459da337, a bug was fixed that involved converting !x & y to !(x & y). The code below shows the same pattern, and thus should perhaps be fixed in the same way. This is not tested and clearly changes the semantics, so it is only something to consider. The semantic patch that makes this change is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @@ expression E1,E2; @@ ( !E1 & !E2 | - !E1 & E2 + !(E1 & E2) ) // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Cc: Tomas Winkler <tomas.winkler@intel.com> Cc: Guy Cohen <guy.cohen@intel.com> Cc: Reinette Chatre <reinette.chatre@intel.com> Cc: Zhu Yi <yi.zhu@intel.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: John W.

* iwlwifi: fix __devexit_p points to __devexit functionsReinette Chatre2008-03-24
| | | | | | | | | | | | | | | | The iwlxxxx_pci_remove functions are not needed when drivers are not compiled as modules - they can thus be discarded at kernel link time. This is already captured by having them as __devexit_p in the pci_driver struct - these are supposed to be pointers to __devexit functions, but was not. This is now fixed.

| | | | | | | | | | | | | | | | | | This adds printk messages with basic information about the driver being loaded. This information includes a summary of the compiled-in features, which simplifies bug-reporting and debugging a lot. Also a firmware ID is printed. This is a unique identifier blob for a specific version of the firmware. This ID is attached to a specific version of the firmware blob in b43-fwcutter (see fwcutter git). This helps users to select the right firmware for their device. This also makes it possible to use automated scripts to fetch and extract the right firmware for the driver. (The script will grep the .ko for the "Firmware-ID: xxx" string.) While the driver might still support other versions of the firmware for backward compatibility, this will always print out the officially supported version, which people _should_ use.
