The assumption that dest af is equal to service af is now unreliable, so we
must specify it manually so as not to copy just the first 4 bytes of a v6
address or doing an illegal read of 16 butes on a v6 address.
We "lie" in two places: for synchronization (which we will explicitly
disallow from happening when we have heterogeneous pools) and for black
hole addresses where there's no real dest.

This is necessary to support heterogeneous pools. For example, if you have
an ipv6 addressed network, you'll want to be able to forward ipv4 traffic
into it.
This patch enforces that destination address family is the same as service
family, as none of the forwarding mechanisms support anything else.
For the old setsockopt mechanism, we simply set the dest address family to
AF_INET as we do with the service.

SCSI Well-known logical units generally don't have any scsi driver
associated with it which means no one will call scsi_autopm_put_device()
on these wlun scsi devices and this would result in keeping the
corresponding scsi device always active (hence LLD can't be suspended as
well). Same exact problem can be seen for other scsi device representing
normal logical unit whose driver is yet to be loaded. This patch fixes
the above problem with this approach:
- make the scsi_autopm_put_device call at the end of scsi_sysfs_add_sdev
to make it balance out the get earlier in the function.
- let drivers do paired get/put calls in their probe methods.

The SCSI specification requires that the second Command Data Byte
should contain the LUN value in its high-order bits if the recipient
device reports SCSI level 2 or below. Nevertheless, some USB
mass-storage devices use those bits for other purposes in
vendor-specific commands. Currently Linux has no way to send such
commands, because the SCSI stack always overwrites the LUN bits.
Testing shows that Windows 7 and XP do not store the LUN bits in the
CDB when sending commands to a USB device. This doesn't matter if the
device uses the Bulk-Only or UAS transports (which virtually all
modern USB mass-storage devices do), as these have a separate
mechanism for sending the LUN value.
Therefore this patch introduces a flag in the Scsi_Host structure to
inform the SCSI midlayer that a transport does not require the LUN
bits to be stored in the CDB, and it makes usb-storage set this flag
for all devices using the Bulk-Only transport. (UAS is handled by a
separate driver, but it doesn't really matter because no SCSI-2 or
lower device is at all likely to use UAS.)
The patch also cleans up the code responsible for storing the LUN
value by adding a bitflag to the scsi_device structure. The test for
whether to stick the LUN value in the CDB can be made when the device
is probed, and stored for future use rather than being made over and
over in the fast path.

Just like CNIC, tristate of these two modules is also dependent on IPV6.
These need to be handled separately as they select CNIC, which can override
tristate for CNIC from 'm' to 'y', which can cause build failures when ipv6 is
compiled as a module even if CNIC's Kconfig will only 'm' or 'n' when ipv6 is
compiled as a module.
