If you have problem to compile Broadcom 802.11 Linux STA driver (version 5.10.27.6) on Kernel 2.6.27 and get error message like the following:

/home/ye/downloads/bcm4328/hybrid_wl/src/wl/sys/wl_iw.c: In function ‘wl_iw_get_scan’:
/home/ye/downloads/bcm4328/hybrid_wl/src/wl/sys/wl_iw.c:934: warning: passing argument 1 of ‘iwe_stream_add_event’ from incompatible pointer type

Then you need to apply the patch: hybrid_wl-5.10.27.6_patch-2.6.27

How to apply the patch:

1. Download the STA driver and the patch.
2. Extract the STA driver and switch to the root of source tree (where Makefile is located).
3. patch -p1 -E < path_to_patch/hybrid_wl_5.10.27.6_patch-2.6.27
