People had been complaining about a lack of testing prior to the final 
release of a kernel.

If this was meant serious, we should try hard to fix all regressions 
reported by people who do test -rc and -git kernels.

As the subject says, this is not a post-2.6.14 regression.

Besides this, Jens (Cc'ed) sent a patch for it:
  http://lkml.org/lkml/2005/11/20/119

Was there a reason why it wasn't applied?

As the subject says, this is not a post-2.6.14 regression.

And reading the discussion on netdev, it seems this wasn't ever expected 
to work without additional netfilter patches.

If this is still present, David should look into it:

If this affects Linus' tree, a patch for it is in -mm.

As the subject says, this is a problem when using an external version of 
this driver.

According to the report perhaps not a post-2.6.14 regression.

But anyways, this should be better debugged.

@Gottfried:
Does it work with kernel 2.6.14.4?
Does it work with kernel 2.6.15-rc6?
If it stil fails, can you send a complete dmesg for 2.6.15-rc6?

Reported against 2.6.13, therefore not a post-2.6.14 regression.
