I personally downloaded this file believing that I was getting a free
GPL driver. Broadcom says so in the patch itself, in the included
LICENSE file, and their website when you click to download it. Red
Hat is shipping it as GPLv2. So either they have to provide the
source (if they have it), stop shipping it, or *at least* stop saying
they are shipping a GPLv2 kernel if they are unwilling/unable to
provide the source.
You missed the discussion where it was pointed out that some firmware
is written in hex directly, as there is no compiler. Good luck with
demanding the source to that dude...

tg3.c is the example I have been using all along.
