Following changes have been made to the qla2xxx FC driver in
preparation for the multi- queue and future SR IOV hardware.
1. scsi_qla_host structure has been changed to contain scsi host
specific data only.
2. A new structure, qla_hw_data is created to contain HBA specific
hardware data.
3. Request and response IO specific data strucures are created.
4. The global list of fcports for the hba is not maintained anymore,
instead a fcport list is construted on per scsi_qla_host.

Greg Wettstein (greg@enjellic.com) noted:
http://article.gmane.org/gmane.linux.scsi/43409
on a reboot of a previously recognized SCST target, the initiator
driver would be unable to re-recognize the device as a target.
It turns out that prior to the SCST software reloading and
returning it's "target-capable" abilities in the PRLI payload,
the HBA would be re-initialized as an initiator-only type port.
Since initiators typically classify themselves as an FCP-2
capable device, both software and firmware do not perform an
explicit logout during port-loss. Unfortunately, as can be seen
by the failure case, when the port (now target-capable) returns,
firmware performs an ADISC without a follow-on PRLI, leaving
stale 'initiator-only' data in the firmware's port database.
Correct the discrepancy by performing the explicit logout during
the transport's request to terminate-rport-io, thus synchronizing
port states and ensuring a follow-on PRLI is performed.

Well, first of all, I don't want to change so many files either.
What I do:
Adding a new parameter "struct bin_attribute *" in the
.read/.write methods for the sysfs binary attributes.
In fact, only the four lines change in fs/sysfs/bin.c and
include/linux/sysfs.h do the real work.
But I have to update all the files that use binary attributes
to make them compatible with the new .read and .write methods.
I'm not sure if I missed any. :(
Why I do this:
For a sysfs attribute, we can get a pointer pointing to the
struct attribute in the .show/.store method,
while we can't do this for the binary attributes.
I don't know why this is different, but this does make it not
so handy to use the binary attributes as the regular ones.
So I think this patch is reasonable. :)
Who benefits from it:
The patch that exposes ACPI tables in sysfs
requires such an improvement.
All the table binary attributes share the same .read method.
Parameter "struct bin_attribute *" is used to get
the table signature and instance number which are used to
distinguish different ACPI table binary attributes.
Without this parameter, we need to offer different .read methods
for different ACPI table binary attributes.
This is impossible as there are various ACPI tables on different
platforms, and we don't know what they are until they are loaded.

sysfs is now completely out of driver/module lifetime game. After
deletion, a sysfs node doesn't access anything outside sysfs proper,
so there's no reason to hold onto the attribute owners. Note that
often the wrong modules were accounted for as owners leading to
accessing removed modules.
This patch kills now unnecessary attribute->owner. Note that with
this change, userland holding a sysfs node does not prevent the
backing module from being unloaded.

iIDMA (Intelligent Interleaved Direct Memory Access) allows for
the HBA hardware to send FC frames at the rate at which they can
be received by a target device. By taking advantage of the
higher link rate, the HBA can maximize bandwidth utilization in a
heterogeneous multi-speed SAN.
Within a fabric topology, port speed detection is done via a Name
Server command (GFPN_ID) followed by a Fabric Management command
(GPSC). In an FCAL/N2N topology, port speed is based on the HBA
link-rate.

As long as the host software (qla2xxx) services the response
