Among our approximatly 20,000 binary packages, I only see
edd_at_ron:~$ apt-cache search fabrics
libmthca-dev - Development files for the libmthca driver
libmthca1 - A userspace driver for Mellanox InfiniBand HCAs
libmthca1-dbg - Debugging symbols for the libmthca driver
I am not aware of anything kernel-specific happening. That said, I could simply be unaware.
Is there a test I could run for you?
Also, if this test depends on the Debian kernel packages, then we're
back to square one as some folks (like myself) run binary kernels,
other may just hand-compile and this test may not work as we may miss
the 'Debian trigger' in those cases.

Yes, but here I can only offer a meek 'dunno, really'. Sorry!
Three out of two people have difficulties with fractions.
