This patch adds support for REPORT TARGET PORT GROUPS. This is used
eg for the multipathing priority callout to determine the path
priority.
With this patch multipath-tools can use the existing mpath_prio_alua
callout to exercise the path priority grouping.

According to the iscsi RFC, we cannot send other requests if
we have sent a logout pdu. This patch enforces this requirement
by blocking the session and suspending the send thread. Userspace
decides if we restart the connection or if we just free everything.

from bhalevy@gmail.com:

It looks like change 652 to libiscsi.c added some dead code around line
670
                if (rc) {
                        spin_unlock_bh(&conn->session->lock);
                        goto again;
                }

since 5 lines above we goto again if (rc).

It looks like the previous if (rc) should go away if we want to put the
ctask before
breaking out of the while loop with "goto again" (see following patch).

The transport class recv mempools are causing slab corruption.
We could hack around netlink's lack of mempool support like dm,
but it is just too ulgy (dm's hack is ugly enough :) when you need
to support broadcast.

This patch removes the recv pools. We have not used them even when
we were allocting 20 MB per session and the system only had 64 MBs.
And we have no pools on the send side and have been ok there. When
Peter's work gets merged we can use that since the network guys
are in favor of that approach and are not going to add mempools
everywhere.

Early ISP2432 parts have a known hardware issue when coming
out of a D3 hot state.  This issue can result in a hung PCIe
link.  Recent firmwares contain a workaround whereby the
stop-firmware mailbox command prevents the ISP from entering
the D3 hot state.

In order to ensure that the workaround succeeded the driver
must verify that the stop-firmware mailbox command completes
successfully.  In the event of a failure, the driver
attempts a shutdown-retry after resetting the ISP and
re-executing firmware.

Stall error handler if attempting recovery while an rport is blocked.
This avoids device offline scenarios due to errors in the error handler.
Also verify that VirtDevice is available before issuing scsi command.
VirtDevice is removed when fc transport removes a target.
