This driver is for Broadcom Netxtreme II 57712 chip. The following
patch contains the driver sources for bnx2fc driver. libfc/libfcoe
changes to enable bnx2fc have already gone through the fcoe
tree. bnx2fc is a SCSI low level driver that interfaces with SCSI
midlayer, libfc, libfcoe, cnic modules. bnx2fc driver uses services
of libfc for slow path operations such as FIP and fabric
discovery. The fast path IO perations are performed after offloading
the session information to the underlying FCoE firmware.

RAID attributes uses scsi_is_sdev_device() to gate some SCSI specific
checking code. This causes two problems. Firstly if SCSI == n just
defining scsi_is_sdev_device() to return false might not be enough to
prevent gcc from emitting the code (and thus referring to undefined
symbols), so this needs surrounding with an ifdef. Secondly, using
scsi_is_sdev_device() when SCSI is either y or m gives a subtle
problem in the m case: raid_attrs must also be m to use the symbol.
Do the usual Kconfig jiggery-pokery to fix this.

Use libfcoe as a common FIP implementation with fcoe.
FIP or non-FIP mode is fully automatic if the firmware
supports and enables it.
Even if FIP is not supported, this uses libfcoe for the non-FIP
handling of FLOGI and its response.
Use the new lport_set_port_id() notification to capture
successful FLOGI responses and port_id resets.
While transitioning between Ethernet and FC mode, all rx and
tx FC frames are queued. In Ethernet mode, all frames are
passed to the exchange manager to capture FLOGI responses.
Change to set data_src_addr to the ctl_src_addr whenever it
would have previously been zero because we're not logged in.
This seems safer so we'll never send a frame with a 0 source MAC.
This also eliminates a special case for sending FLOGI frames.

libFC is composed of 4 blocks supported by an exchange manager
and a framing library. The upper 4 layers are fc_lport, fc_disc,
fc_rport and fc_fcp. A LLD that uses libfc could choose to
either use libfc's block, or using the transport template
defined in libfc.h, override one or more blocks with its own
implementation.
The EM (Exchange Manager) manages exhcanges/sequences for all
commands- ELS, CT and FCP.
The framing library frames ELS and CT commands.
The fc_lport block manages the library's representation of the
host's FC enabled ports.
The fc_disc block manages discovery of targets as well as
handling changes that occur in the FC fabric (via. RSCN events).
The fc_rport block manages the library's representation of other
entities in the FC fabric. Currently the library uses this block
for targets, its peer when in point-to-point mode and the
directory server, but can be extended for other entities if
needed.
The fc_fcp block interacts with the scsi-ml and handles all
I/O.
