The following series makes changes to libfc and libfcoe to provide
FIP support for the fnic driver. The patch to the fnic driver will
be sent separately.
The fnic firmware may not support FIP, so a mode is added to libfcoe
to run solely in non-FIP mode.
The FIP debug messages are improved to include the host number, to
distinguish between different device instances.
The FIP receive handling is changed to allow the fnic driver to
queue frames to it directly from the ISR level. This just changes
the locks from _bh locks to _irq locks, which are provided internally
by the skb layer.
A bug fix changes the way link is reported to libfc to always report
the physical link, and not to report link down when the FCF times out
or we get a Link Reset message.
A somewhat-related bug fix to libfc stops it from doing a WARN_ON when
getting a FLOGI timeout response in RESET state.
Finally, add a notification hook the LLD can use to get notified when
the FC-ID is assigned. This eliminates the need to intercept the ELS
send and response functions, which we were going to have to either
duplicate in fnic, or re-engineer to put in libfcoe. The callback
will be a better method to handle point-to-point mode eventually.
fcoe.ko could be modified to use this callback as well later.

Joe Eykholt (6):
libfc: notify LLD when an FC_ID is assigned to the local port.
libfc: don't WARN_ON in lport_timeout for RESET state
libfcoe: FIP should report link to libfc whether selected or not
libfcoe: fip: allow FIP receive to be called from IRQ.
libfcoe: fip: use SCSI host number to identify debug messages.
libfcoe: Allow FIP to be disabled by the driver
