Hi all,

[David/James, we need a little help with this one...this single patch
spans scsi and netdev, so we're not sure which tree/maintainer needs
to pick up the patch.  Please advise.  It's for 2.6.31.  The patch is
against linux-2.6.git.]
Ah, finally. I was actually waiting someone would spot this ...
The Cisco enic 10G Ethernet driver and the fnic FCoE HBA driver share
much of the same hardware-access code because enic and fnic devices are
really two functions on a converged-I/O PCIe device.  This patch
consolidates the shared code into one shared module, thus eliminating
the code duplication.  No functional changes are made by the patch.

Why weren't these consolidated in the first place?  fnic went in late in
2.6.30 on the scsi branch (merge exception for new drivers), and it was
too late to modify enic which was already included in 2.6.28.
Hmm. Seeing that we're getting more and more of these type of drivers
(cf bnx2 / bnx2i / cnic, enic / fnic, and at least one other in the pipe)
one does wonder whether we should establish a separate directory for
these kind of things.
drivers/virtual or drivers/shared springs to mind.

Having them in the network directory is probably not the
correct choice.

Cheers,

Hannes
