The biggest difference is that libfc no longer allocates a sequence
and exchange for incoming requests, and that eliminates a parameter
on the receive function. This was done to help performance and
might help on short reads sometime in the future.
This also fixes an error in ft_send_read_data() that exceeds the
skb's SG list length limit on long reads when the NIC
supports large send offload.
I also made other minor changes like adding debugging.

except for line number changes and a few interface changes imposed
by differences in libfc between 2.6.35 and 2.6.36, mostly due to the
change which doesn't allocate an exchange and sequence for incoming
requests.

I believe this was causing a race leading to a WARN in fc_seq_send that
the sequence initiative wasn't held in ft_send_response(). It also caused
a problem for tcm_fc.

The individual patches are a subset of the earlier ones, with
only line number changes to apply cleanly.

while gcc honors this attribute. The result is that
sizeof(struct fcoe_rcv_info) is 48 when the header include/scsi/fc_frame.h is
compiled with gcc and that sizeof(struct fcoe_rcv_info) > 48 when the same
header is compiled by sparse. As a result, compilation with sparse fails due
to the BUILD_BUG_ON() statement in the function fcoe_dev_from_skb(), even
when checking a vanilla Linux kernel with sparse. The patch below slightly
modifies include/scsi/fc_frame.h such that gcc and sparse interpret this header
in the same way.
Note: it is fine to revert this patch once the behavior of gcc and sparse is
again in sync.

Add a method for template get_initiator_port_transport_id()
to allow persistent reservations to work.
Initialize struct ft_sess more fully before scst_register_session()
so that ft_get_transport_id() can use it.

The target template max_hw_pending_time was zero, causing
premature timeouts and a fast retry in scst_hw_pending_work_fn().
Set it to 20 seconds, like qla2x00t does, for now.
It could be the wrong thing for tape, but should be
plenty long enough for disks.

that accepts FCP requests from libfc HBAs running Fibre Channel
