When a sequence times out we have no idea what happened to the
frame. And we do not know if we will ever receive the frame.
Hence we cannot re-use the xid as we would risk data corruption
if the xid had been re-used and the timed out frame would be
received after that.
So we need to quarantine the xid until the lport is reset.
Yes, I know this will (eventually) deplete the xid pool.
But for now it's the safest method.

While the FCoE initiator driver invokes fc_exch_done() from inside
the libfc response handler, FCoE target drivers typically invoke
fc_exch_done() from outside the libfc response handler. The object
fc_exch.arg points at may disappear as soon as fc_exch_done() has
finished. So it's important not to invoke the response handler
function after fc_exch_done() has finished. Modify libfc such that
this guarantee is provided if fc_exch_done() is invoked from
outside a response handler. This patch fixes a sporadic crash in
FCoE target implementations after a command has been aborted.

This patch adds support for Fabric Device Management
Interface as per FC-GS-4 spec. in libfc. Any driver
making use of libfc can enable fdmi state machine
for a given lport.
If lport has enabled FDMI support the lport state
machine will transition into FDMI after completing
the DNS states and before entering the SCR state.
The FDMI state transition is such that if there is an
error, it won't stop the lport state machine from
transitioning and the it will behave as if there was
no FDMI support.
The FDMI HBA attributes are registed with the Management
server via Register HBA (RHBA) command and the port
attributes are reigstered using the Register Port(RPA)
command.

Allow FC-4 provider modules to hook into libfc, mostly for targets.
This should allow any FC-4 module to handle PRLI requests and maintain
process-association states.
Each provider registers its ops with libfc and then will be called for
any incoming PRLI for that FC-4 type on any instance. The provider
can decide whether to handle that particular instance using any method
it likes, such as ACLs or other configuration information.
A count is kept of the number of successful PRLIs from the remote port.
Providers are called back with an implicit PRLO when the remote port
is about to be deleted or has been reset.
fc_lport_recv_req() now sends incoming FC-4 requests to FC-4 providers,
and there is a built-in provider always registered for handling
incoming ELS requests.
The call to provider recv() routines uses rcu_read_lock()
so that providers aren't removed during the call. That lock is very
cheap and shouldn't affect any performance on ELS requests.
Providers can rely on the RCU lock to protect a session lookup as well.

The statistics for InputMegabytes and OutputMegabytes are
misnamed. They're accumulating bytes, not megabytes.
The statistic returned via /sys must be in megabytes, however,
which is what the HBA-API wants. The FCP code needs to accumulate
it in bytes and then divide by 1,000,000 (not 2^20) before it
presented via sysfs.
This affects fcoe.ko only, not fnic. The fnic driver
correctly by accumulating bytes and then converts to megabytes.
I checked that libhbalinux is using the /sys file directly without
conversion.
BTW, qla2xxx does divide by 2^20, which I'm not fixing here.
