Since I was having performance issues with the open source driver I started using the driver provided by Broadcom:
http://www.broadcom.com/support/802.11/linux_sta.php
On the newer kernel there are two compilation issues which need patching.
The patches provided below are for version 5.100.82.112 of the driver.
The first issue which I hit was the following error during compilation
/usr/src/linux-sta/src/wl/sys/wl_linux.c:396:2: error: unknown field ‘ndo_set_multicast_list’ specified in initializer /usr/src/linux-sta/src/wl/sys/wl_linux.c:396:2: warning: initialization from incompatible pointer type [enabled by default] /usr/src/linux-sta/src/wl/sys/wl_linux.c:396:2: warning: (near initialization for ‘wl_netdev_ops.ndo_validate_addr’) [enabled by default] make[2]: *** [/usr/src/linux-sta/src/wl/sys/wl_linux.o] Error 1 make[1]: *** [_module_/usr/src/linux-sta] Error 2 make[1]: Leaving directory `/usr/src/kernels/3.4.0-1.fc17.i686'
The secon issue is the following error
/usr/src/linux-sta/src/wl/sys/wl_linux.c:43:24: fatal error: asm/system.h: No such file or directory
which is caused by dropping the header asm/system.h in kernel 3.4 in favor of 5 new headers.
More about this can be read here:
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=0195c002
Here is a patch witch fixes both of the issues.
You can download the patch from pastebin:
http://pastebin.com/C8TZ8q88
I am pasting the code in pastebin, because blogger.com has an "incredibly good" editor and I am fighting for half an hour to make it not hiding most of the source code and as you can see he wins :).
place this text in a file and save it
then go in the dirver directory in my case:
cd /usr/src/linux-sta/src/wl/sys/
and run the patch
patch -p0 < /path/where/the/you/saved/the/patchfile.patch
then try to compile as usual
cd /usr/src/linux-sta/
make clean
make install
depmod -a
modprobe wl
