The attached patches add sysfs files for the chap settings
to the iscsi transport class, iscsi_tcp and ib_iser. This is
needed for software iscsi because there are times when iscsid
can die and it will need to reread the values it was using.
And it is needed by qla4xxx for basic management opertaions.
This patch does not hook in qla4xxx yet, because I am not sure
the mbx command to use.

This patch fixes handling of expected datasn/r2tsn as received from
target. It is done according to: T10 rfc3720 section 3.2.2.3. Data Sequencing.

. unify expected datasn/r2tsn into one counter
. calculate than check expected datasn/r2tsn. On error print a message
  and fail the request. (TODO use iscsi retransmits)
. remove the FIXME   ;)
. avoid zero length memset

For iscsi root boot, software iscsi needs to know what the BIOS/OF
initiator used for the initiator name so this puts it in sysfs
for userspace to be able to pick up.

For hw iscsi, it is nice to see what the card is using.

This patch adds the new param, and hooks in qla4xxx, iscsi_tcp, and ib_iser.

Currently accessing the scsi host private data is rather messy because
it comes as an unsigned long that always needs a cast first.  This patch
introduces a helper that does the cast called shost_priv.  It's similar
in spirit to netdev_priv for network drivers.

This is the first patch introducing the macro, and the second patch
in the series will convert esp and it's subdrivers as an example.
Further conversion will wait until the helper is in the tree to make
patch juggling easier.

The current code is leaking a reference to dreq->kref when the calls to
nfs_direct_read_schedule() and nfs_direct_write_schedule() return an
error.
This patch moves the call to kref_put() from nfs_direct_wait() back into
nfs_direct_read() and nfs_direct_write() (which are the functions that
actually took the reference in the first place) fixing the leak.

This restores the previously removed netif_poll_enable call in e1000_open.
It's needed on all but the first call to e1000_open for a NIC as
e1000_close always calls netif_poll_disable.

netif_poll_enable can only be called safely if no polls have been
scheduled.  This should be the case as long as we don't enter our IRQ
handler.

In order to guarantee this we explicitly disable IRQs as early as possible
when we're probing the NIC.
