Bugzilla Bug 181984

Upgraded my system to use Kernel vanilla-sources 2.6.22-rc4, but now I can't
install rt2500.

 * checking rt2500-1.1.0_pre2007020911.tar.gz ;-) ...                          
                                     [ ok ]
 * Determining the location of the kernel source code
 * Found kernel source directory:
 *     /usr/src/linux
 * Found sources for kernel version:
 *     2.6.22-rc4
 * Checking for suitable kernel configuration options...
 *   CONFIG_NET_RADIO:   is not set when it should be.
 * Please check to make sure these options are set correctly.
 * Failure to do so may cause unexpected problems.
 * Once you have satisfied these options, please try merging
 * this package again.


Reproducible: Always

Steps to Reproduce:
1. emerge --sync
2. emerge rt2500

This is *not* a Gentoo bugzilla product bug; read the descriptions please.

I also have this problem. I tried removing the CONFIG_NET_RADIO check from the
ebuild, but it still failed due to a compile error. I believe some kernel APIs
changed since 2007020911.

I used the latest CVS snapshot (2007062815) from the driver homepage (
http://rt2x00.serialmonkey.com ) and got it to compile. The module loads and I
can see an access point via RaConfig2500. I haven't done any further testing,
I'm away from home on vacation.

This bug should really be closed as a duplicate of Bug #181973 because the
"fix" to make the driver work with 2.6.22 is to do a version bump to a newer
CVS snapshot.

We need to fix this in the stable tree before 2.6.22 goes stable, so there may
not be enough time to add a new snapshot AND mark it stable. If someone wants
to post the compiler errors, I'll comment on how they can be fixed.

The CONFIG_CHECK situation can be fixed with something along these lines:

Here are the errors I got when I tried to build rt2500-1.1.0_pre2007020911
against vanilla sources 2.6.22.1

/var/tmp/portage/net-wireless/rt2500-1.1.0_pre2007020911/work/rt2500-cvs-2007020911/Module/rtmp_main.c:

replace pci_module_init with pci_register_driver (unconditionally)

error: 'struct sk_buff' has no member named 'mac'

replace:

skb->mac.raw = skb->data;

with:

skb_reset_mac_header(skb)


Both changes are fine to apply unconditionally.
