Do umac or cx3110x use sk_buff.cb (command buffer)?

[Clemens Eisserer]

Hello,

There are several networking features that cause the sk_buff structure
to grow, leading to crashes when loading cx3110x.

1. Would it be enough to recompile cx3110x, or does umac also use the
sk_buff structure?

2. I've been able to work-arround those issue by shrinking the
command-buffer field cb a bit, to make sure structure stays the same
size.

For the kernel that modification doesn't seem to be a problem, because
everywhere sizeof(cb) is used.
However I don't know wether cx3110x or umac use this command-buffer.
I had a look at cx3110x and it doesn't seem to be using cb, but whats
about umac?
I am uncertain because all the memory management routines assicoated
with cb are marked with inline, so maybe somewhere in those
not-recompiled modules there are wrong size constants lurking arround.

Thank you in advance, lg Clemens
