broadcom-sta-5.100.82.112-r3.ebuild

broadcom-sta-5.100.82.112 has long had several outstanding issues. I propose this ebuild as broadcom-sta-5.100.82.112-r3.ebuild.

You can track my work in the tbc overlay.

The following issues have been fixed:
bug #306189 - a non-fatal check was introduced to warn against CONFIG_LIB80211_CRYPT_TKIP not being selected, which renders WPA functionality unavailable. This affects almost all recent routers.

Additional explanatory messages were added for various CONFIG_CHECKS.

check_kernel_built from linux-info.eclass gets called in order to make sure the kernel is ready to deal with external modules.

bug #407667 - replaced broadcom-sta-5.100.82.112-linux-3.2.patch with a similar patch that preserves multicast functionality. Can be found in the bugreport.

style issue: converted the sed in the ebuild for working with kernel 3.4 into patch file broadcom-sta-5.100.82.112-linux-3.4.patch, so it can actually fail if it doesn't fit anymore

bug #437898 - kernel oops upon loading with kernel 3.6 and later. It refers to a patch on https://bugzilla.rpmfusion.org/show_bug.cgi?id=2526 to fix the issue. This patch is incorporated in broadcom-sta-5.100.82.112-linux-3.6.patch, along with other adaptations. The patch actually loaded in this ebuild is identical to https://github.com/Sabayon/for-gentoo/blob/master/net-wireless/broadcom-sta/files/broadcom-sta-5.100.82.112-linux-3.6.patch

bug #459208 - attached patch gets loaded as broadcom-sta-5.100.82.112-linux-3.8.patch, makes it work with kernel 3.8

another patch from sabayon: "lxnay 2 days ago [net-wireless/broadcom-sta] more Linux 3.9 love, wheeeee" - gets loaded as broadcom-sta-5.100.82.112-linux-3.9.patch

bug #399747 - broadcom-sta-5.100.82.112-remove-rssi-errors.patch - silences EINVAL errors and is not actually a fix.

IMPORTANT NOTICE:
This ebuild was tested to compile fine against the following kernels:
linux-3.0.35-gentoo
linux-3.0.75-gentoo
linux-3.2.44-gentoo
linux-3.4.34-gentoo
linux-3.4.42-gentoo
linux-3.5.7-gentoo
linux-3.6.11-gentoo-r1
linux-3.7.10-gentoo-r1
linux-3.8.10-gentoo
linux-3.8.3-gentoo-r1
linux-3.8.4-gentoo
linux-3.8.5-gentoo
linux-3.8.6-gentoo
linux-3.8.7-gentoo
linux-3.8.8-gentoo
linux-3.8.9-gentoo
linux-3.9.0-gentoo

It was tested to load fine with
linux-3.8.10-gentoo
linux-3.7.10-gentoo-r1

However, i do get frequent disconnect/reconnects without ever obtaining an IP address with anything beyond kernel 3.5. Since I have the same problem with brcmsmac, I will need to further investigate.
Please comment if you get similar/different results.
My hardware is a BCM4313 [14e4:4727] (rev 01).

The files pasted here so far are the new files i added to (and are identical with the ones in) my commit 86a1ace73a9f6ae59ba442c957dfc7af59d70dcd in the tbc overlay.
