net_device::dev_id should not be used merely to indicate a VI index,
as it affects the way the local part of IPv6 addresses is normally
generated.
This field was intended for use where multiple devices may share a
single assigned MAC address and need to have different IPv6 addresses.
T4 VIs each have their own MAC address.

Commit da12c90e09
"netlink: Add compare function for netlink_table"
only set compare at the time we create kernel netlink,
and reset compare to NULL at the time we finially
release netlink socket, but netlink_lookup wants
the compare exist always.
So we should set compare after we allocate nl_table,
and never reset it. make comapre exist all the time.

commit 6648bd7e0e (ipv4: Add sysctl knob to control

Basically I grab the doc from the description of commit 41063e9dd1
(ipv4: Early TCP socket demux.) and the above commit.

The TUN_PERSIST flag is not reported at all -- both TUNGETIFF, and sysfs
"flags" attribute skip one. Knowing whether a device is persistent or not
is critical for checkpoint-restore, thus I propose to add the read-only
IFF_PERSIST one for this.
Setting this new IFF_PERSIST is hardly possible, as TUNSETIFF doesn't check
for unknown flags being zero and thus there can be trash.

====================
This pull request is intended for the 3.11 stream...
One big highlight is the cw1200 driver the ST-E CW1100 & CW1200
WLAN chipsets. This one has been lingering for a while, lacking
some review comments. Once started getting pulled into linux-next,
it got a bit more attention and a number of improvements were made
over the initial cut. No doubt there will be more changes ahead,
but I think it is looking alright at this point.
Along with that, there is the usual flurry of updates to the mac80211
core and the iwlwifi, mwifiex, ath9k, rt2x00, wil6210, and other
drivers. A few of the highlights are some rt2x00 refactoring/cleanup
by Gabor Juhos, some rt2800 hardware support enhancements by Stanislaw
Gruszka, some iwlwifi power management updates from Alexander Bondar,
some enhanced bcma SPROM support from Rafał Miłecki, and a variety
of other things here and there.

Commit 9f86134155 (sh_eth: remove SH_ETH_HAS_TSU)
removes 'const' from 'sh_eth_netdev_ops' and modifies it in case TSU registers
are present. I've originally suggested to Iwamatsu-san to split this structure
in two instead and afterwards Dave M. suggested doing the same.
Split 'sh_eth_netdev_ops_tsu' from 'sh_eth_netdev_ops', making both 'const', and
assigning 'ndev->detdev_ops' depending on the presence of TSU registers.

Older Single Queue (SQ_SG_MODE) devices like TSEC (i.e. mpc83xx)
don't feature the frame receive indication bits (RXF) in RSTAT.
For these and for the rest of the SQ_SG_MODE devices, provide the
appropiate polling routine that handles a single pair of Rx/Tx
BD rings, removing the overhead incurred by the multiple queues/
multiple interrupt group devices (veTSEC/ eTSEC2.0 devices).
So this is primarily a fix for the TSEC devices.

This patch removes synchronize_rcu() from function
__team_queue_override_port_del(). That can be done because it is ok to
do list_del_rcu() and list_add_tail_rcu() on the same list_head member
without calling synchronize_rcu() in between. A bit of refactoring
needed to be done because INIT_LIST_HEAD needed to be removed (to not
kill the forward pointer) as well.
