This patch series adds a sysfs layer to libfcoe. It adds
a sysfs instance for FIP controllers (a SW entity) and
discovered Fibre Channel Forwarders (FCFs), which are
simply FCoE switches.
The new sysfs code is used by any driver that currently
uses libfcoe, namely fcoe.ko and bnx2fc_fcoe.ko. Any other
FCoE capable device that wishes to use the high-level APIs
defined in fcoe_syfs.h may, without having to use the
the protocol processing portions of libfcoe.
The code borrows heavily from the FC Transport, but is
less complicated because it does not need to interact
with the SCSI layer directly.
I think one thing to consider with this series is that
drivers, such as traditional HBAs, which wish to use
this infrastructure will now need to depend on libfcoe.ko.
It was either this or create a superfluous kernel module;
I think libfcoe is an appropriate place for this code.
This series was created against scsi-misc + 9 patches
mailed by me to linux-scsi on 03/09/12. (Note that 10
patches were mailed, but that patch 01/10 will be dropped)
I'm not sure if there's somewhere I should cross-post
this for general sysfs review. I don't think I'm doing
anything odd; I added Greg K-H to the CC list to try and
get some sysfs eyes on this code.
