34a5b4b6af iwlwifi: do not re-configure
HT40 after associated
Fix the case of HT40 after association on specified AP, but it break the
association for some APs and cause not able to establish connection.
We need to address HT40 before and after addociation.

Command cancel path cancels the current command and moves
it to free command queue. While doing that it deletes the
command entry from the pending list. This is not correct
as the entry has been already deleted from the pending
list at 'mwifiex_exec_next_cmd'. Fixing it.
Also making sure the stale command pointer is cleaned and

Same fix as 731abb9cb2 for ipip and sit tunnel.
Commit 1c5cae815d removed an explicit call to dev_alloc_name in
ipip_tunnel_locate and ipip6_tunnel_locate, because register_netdevice
will now create a valid name, however the tunnel keeps a copy of the
name in the private parms structure. Fix this by copying the name back
after register_netdevice has successfully returned.
This shows up if you do a simple tunnel add, followed by a tunnel show:
$ sudo ip tunnel add mode ipip remote 10.2.20.211
$ ip tunnel
tunl0: ip/ip remote any local any ttl inherit nopmtudisc
tunl%d: ip/ip remote 10.2.20.211 local any ttl inherit
$ sudo ip tunnel add mode sit remote 10.2.20.212

There is no obvious reason to add a default multicast route for loopback
devices, otherwise there would be a route entry whose dst.error set to
-ENETUNREACH that would blocking all multicast packets.
====================
[ more detailed explanation ]
The problem is that the resulting routing table depends on the sequence
of interface's initialization and in some situation, that would block all
muticast packets. Suppose there are two interfaces on my computer
(lo and eth0), if we initailize 'lo' before 'eth0', the resuting routing
table(for multicast) would be
# ip -6 route show | grep ff00::
unreachable ff00::/8 dev lo metric 256 error -101
ff00::/8 dev eth0 metric 256
When sending multicasting packets, routing subsystem will return the first
route entry which with a error set to -101(ENETUNREACH).
I know the kernel will set the default ipv6 address for 'lo' when it is up
and won't set the default multicast route for it, but there is no reason to
stop 'init' program from setting address for 'lo', and that is exactly what
systemd did.
I am sure there is something wrong with kernel or systemd, currently I preferred
kernel caused this problem.

ssb: fix init regression of hostmode PCI core
In ssb_pcicore_fix_sprom_core_index() the sprom on the PCI core is
accessed, but the sprom only exists when the ssb bus is connected over
a PCI bus to the rest of the system and not when the SSB Bus is the
main system bus. SoCs sometimes have a PCI host controller and there
this code will not be executed, but there are some old SoCs with an PCI
controller in client mode around and ssb_pcicore_fix_sprom_core_index()
should not be called on these devices too. The PCI controller on these
devices are unused, but without this fix it results in an Data bus
error when it gets initialized.

Emmanuel noticed that when mac80211 stops the queues
for aggregation that can leave a packet pending. This
packet will be given to the driver after the AMPDU
callback, but as a non-aggregated packet which messes
up the sequence number etc.
I also noticed by looking at the code that if packets
are being processed while we clear the WANT_START bit,
they might see it cleared already and queue up on
tid_tx->pending. If the driver then rejects the new
aggregation session we leak the packet.
Fix both of these issues by changing this code to not
stop the queues at all. Instead, let packets queue up
on the tid_tx->pending queue instead of letting them
get to the driver, and add code to recover properly
in case the driver rejects the session.
(The patch looks large because it has to move two
functions to before their new use.)

The code for setting the address of the internal TBI PHY was
convoluted enough without a maze of ifdefs. Clean it up a bit
so we allow the logic to fail down to -ENODEV at the end of
the if/else ladder, rather than using ifdefs to repeat the same
failure code over and over.
Also, remove the support for the auto-configuration. I'm not aware of

The pdev->id is used in several places for different purpose. All
these uses assume it's always the id of fec device which is >= 0.
However this is only true for non-DT case. When DT plays, pdev->id
is always -1, which will break these pdev->id users.
Instead of fixing all these users one by one, this patch introduces
a new member 'dev_id' to 'struct fec_enet_private' for holding the
correct fec device id, and replaces all the existing uses of pdev->id

In case of a client roaming from node A to node B, the latter have to mark the
corresponding global entry with TT_CLIENT_ROAM (instead of TT_CLIENT_PENDING).
Marking a global entry with TT_CLIENT_PENDING will end up in keeping such entry
forever (because this flag is only meant to be used with local entries and it is
never checked on global ones).
In the worst case (all the clients roaming to the same node A) the local and the

Since 92fc43b415, rtl8169_tx_timeout ends up
resetting Rx and Tx indexes and thus racing with the NAPI handler via
-> rtl8169_hw_reset
-> rtl_hw_reset
-> rtl8169_init_ring_indexes
What about returning to the original state ?
rtl_hw_reset is only used by rtl8169_hw_reset and rtl8169_init_one.
The latter does not need rtl8169_init_ring_indexes because the indexes
still contain their original values from the newly allocated network
device private data area (i.e. 0).
rtl8169_hw_reset is used by:
1. rtl8169_down
Helper for rtl8169_close. rtl8169_open explicitely inits the indexes
anyway.
2. rtl8169_pcierr_interrupt
Indexes are set by rtl8169_reinit_task.
3. rtl8169_interrupt
rtl8169_hw_reset is needed when the device goes down. See 1.
4. rtl_shutdown
System shutdown handler. Indexes are irrelevant.
5. rtl8169_reset_task
Indexes must be set before rtl_hw_start is called.
6. rtl8169_tx_timeout
Indexes should not be set. This is the job of rtl8169_reset_task anyway.
The removal of rtl8169_hw_reset in rtl8169_tx_timeout and its move in
rtl8169_reset_task do not change the analysis.

Realtek has specified that the post 8168c gigabit chips and the post
8105e fast ethernet chips recover automatically from a Rx FIFO overflow.
The driver does not need to clear the RxFIFOOver bit of IntrStatus and
it should rather avoid messing it.
The implementation deserves some explanation:
1. events outside of the intr_event bit mask are now ignored. It enforces
a no-processing policy for the events that either should not be there
or should be ignored.
2. RxFIFOOver was already ignored in rtl_cfg_infos[RTL_CFG_1] for the
whole 8168 line of chips with two exceptions:
- RTL_GIGA_MAC_VER_22 since b5ba6d12bd
("use RxFIFO overflow workaround for 8168c chipset.").
This one should now be correctly handled.
- RTL_GIGA_MAC_VER_11 (8168b) which requires a different Rx FIFO
overflow processing.
Though it does not conform to Realtek suggestion above, the updated
driver includes no change for RTL_GIGA_MAC_VER_12 and RTL_GIGA_MAC_VER_17.
Both are 8168b. RTL_GIGA_MAC_VER_12 is common and a bit old so I'd rather
wait for experimental evidence that the change suggested by Realtek really
helps or does not hurt in unexpected ways.
Removed case statements in rtl8169_interrupt are only 8168 relevant.
3. RxFIFOOver is masked for post 8105e 810x chips, namely the sole 8105e
(RTL_GIGA_MAC_VER_30) itself.

I've received complaints that the numa_node attribute for family
15h model 00-0fh (e.g. Interlagos) northbridge functions shows
-1 instead of the proper node ID.
Correct this with attached quirks (similar to quirks for other
AMD CPU families used in multi-socket systems).
