commit 7972326a26b5bf8dc2adac575c4e03ee7e9d193a upstream.
This can be reproduced by bind/unbind the driver multiple times
in AM3517 board.
Analysis revealed that rtl8187_start() was invoked before probe
finishes(ie. before the mutex is initialized).
INFO: trying to register non-static key.
the code is fine but needs lockdep annotation.

commit 182b1917109892ab9f26d66bfdcbc4ba6f0a0a65 upstream.
When ath9k was switched over to use the mac80211 intermediate queues,
node cleanup now drains the mac80211 queues. However, this call path is
not protected by rcu_read_lock() as it was previously entirely internal
to the driver which uses its own locking.
This leads to a possible rcu_dereference() without holding
rcu_read_lock(); but only if a station is cleaned up while having
packets queued on the TXQ. Fix this by adding the rcu_read_lock() to the
caller in ath9k.

On receiving a packet the state index points to the rstate which must be
used to fill up IP and TCP headers. But if the state index points to a
rstate which is unitialized, i.e. filled with zeros, it gets stuck in an
infinite loop inside ip_fast_csum trying to compute the ip checsum of a

[ Upstream commit 6e8814ceb7e8f468659ef9253bd212c07ae19584 ]
Global pause and PFC configuration should be mutually exclusive (i.e. only
one of them at most can be set). However, once PFC was turned off,
driver automatically turned Global pause on. This is a bug.
Fix the driver behaviour to turn off PFC/Global once the user turned the
other on.
This also fixed a weird behaviour that at a current time, the profile
had both PFC and global pause configuration turned on, which is
Hardware-wise impossible and caused returning false positive indication
to query tools.
In addition, fix error code when setting global pause or PFC to change
metadata only upon successful change.
Also, removed useless debug print.

[ Upstream commit a117f73dc2430443f23e18367fa545981129c1a6 ]
When mlx5_core is loaded it is expected to sync ports
with all vxlan devices so it can support vxlan encap/decap.
This is done via udp_tunnel_get_rx_info(). Currently this
call is set in mlx5e_nic_enable() and if the netdev is not in
NETREG_REGISTERED state it will not be called.
Normally on load the netdev state is not NETREG_REGISTERED
so udp_tunnel_get_rx_info() will not be called.
Moving udp_tunnel_get_rx_info() to mlx5e_open() so
it will be called on netdev UP event and allow encap/decap.

[ Upstream commit 1489bbd10e16079ce30a53d3c22a431fd47af791 ]
The NSP default buffer is a piece of NFP memory where additional
command data can be placed. Its format has been copied from
host buffer, but the PCIe selection bits do not make sense in
this case. If those get masked out from a NFP address - writes
to random place in the chip memory may be issued and crash the
device.
Even in the general NSP buffer case, it doesn't make sense to have the
PCIe selection bits there anymore. These are unused at the moment, and
when it becomes necessary, the PCIe selection bits should rather be
moved to another register to utilise more bits for the buffer address.
This has never been an issue because the buffer used to be
allocated in memory with less-than-38-bit-long address but that
is about to change.

[ Upstream commit af1607c37d9d85a66fbcf43b7f11bf3d94b9bb69 ]
For NIC flows, the parsed attributes are not freed when we exit
successfully from mlx5e_configure_flower().
There is possible double free for eswitch flows. If error is returned
from rhashtable_insert_fast(), the parse attrs will be freed in
mlx5e_tc_del_flow(), but they will be freed again before exiting
mlx5e_configure_flower().
To fix both issues we do the following:
(1) change the condition that determines if to issue the free call to
check if this flow is NIC flow, or it does not have encap action.
(2) reorder the code such that that the check and free calls are done
before we attempt to add into the hash table.

[ Upstream commit 423c9db29943cfc43e3a408192e9efa4178af6a1 ]
Currently we use the global ipv6_stub var to access the ipv6 global
nd table. This practice gets us to troubles when the stub is only partially
set e.g when ipv6 is loaded under the disabled policy. In this case, as of commit
343d60aada5a ("ipv6: change ipv6_stub_impl.ipv6_dst_lookup to take net argument")
the stub is not null, but stub->nd_tbl is and we crash.
As we can access the ipv6 nd_tbl directly, the fix is just to avoid the
reference through the stub. There is one place in the code where we
issue ipv6 route lookup and keep doing it through the stub, but that
mentioned commit makes sure we get -EAFNOSUPPORT from the stack.

[ Upstream commit 48bfc39791b8b4a25f165e711f18b9c1617cefbc ]
The default TX moderation mode was mistakenly set to CQE based. The
intention was to add a control ability in order to improve some specific
use-cases. In general, we prefer to use EQE based moderation as it gives
much better numbers for the common cases.
CQE based causes a degradation in the common case since it resets the
moderation timer on CQE generation. This causes an issue when TSO is
well utilized (large TSO sessions). The timer is set to 16us so traffic
of ~64KB TSO sessions per second would mean timer reset (CQE per TSO
session -> long time between CQEs). In this case we quickly reach the
tcp_limit_output_bytes (256KB by default) and cause a halt in TX traffic.
By setting EQE based moderation we make sure timer would expire after
16us regardless of the packet rate.
This fixes an up to 40% packet rate and up to 23% bandwidth degradtions.

This is actually a dead lock caused by sync slave hwaddr from master when
the master is the slave's 'slave'. This dead loop check is actually done
by netdev_master_upper_dev_link. However, Commit 1f718f0f4f97 ("bonding:
populate neighbour's private on enslave") moved it after dev_mc_sync.
This patch is to fix it by moving dev_mc_sync after master_upper_dev_link,
so that this loop check would be earlier than dev_mc_sync. It also moves
if (mode == BOND_MODE_8023AD) into if (!bond_uses_primary) clause as an
improvement.
Note team driver also has this issue, I will fix it in another patch.

[ Upstream commit 19c9ea363a244f85f90a424f9936e6d56449e33c ]
pci_set_drvdata() is called only after registering the net_device,
therefore we could run into a NPE if one of the functions using
driver_data is called before it's set.
Fix this by calling pci_set_drvdata() before registering the
net_device.
This fix is a candidate for stable. As far as I can see the
bug has been there in kernel version 3.2 already, therefore
I can't provide a reference which commit is fixed by it.
The fix may need small adjustments per kernel version because

[ Upstream commit bfacfb457b36911a10140b8cb3ce76a74883ac5a ]
Once dst has been cached in socket via sk_setup_caps(),
it is illegal to call ip_rt_put() (or dst_release()),
since sk_setup_caps() did not change dst refcount.
We can still dereference it since we hold socket lock.

Add check of coalescing parameters received through ethtool are within
range of values supported by the HW.
Driver gets the coalescing rx/tx-usecs and rx/tx-frames as set by the
users through ethtool. The ethtool support up to 32 bit value for each.
However, mlx5 modify cq limits the coalescing time parameter to 12 bit
and coalescing frames parameters to 16 bits.
Return out of range error if user tries to set these parameters to
higher values.

[ Upstream commit 44b034b406211fc103159f82b9e601e05675c739 ]
In i40evf_reset_task we use netif_running() to determine whether or not
the device is currently up. This allows us to properly free queue memory
and shut down things before we request the hardware reset.
It turns out that we cannot be guaranteed of netif_running() returning
false until the device is fully up, as the kernel core code sets
__LINK_STATE_START prior to calling .ndo_open. Since we're not holding
the rtnl_lock(), it's possible that the driver's i40evf_open handler
function is currently being called while we're resetting.
We can't simply hold the rtnl_lock() while checking netif_running() as
this could cause a deadlock with the i40evf_open() function.
Additionally, we can't avoid the deadlock by holding the rtnl_lock()
over the whole reset path, as this essentially serializes all resets,
and can cause massive delays if we have multiple VFs on a system.
Instead, lets just check our own internal state __I40EVF_RUNNING state
field. This allows us to ensure that the state is correct and is only
set after we've finished bringing the device up.
Without this change we might free data structures about device queues
and other memory before they've been fully allocated.

This also eliminates the possibility of a permanent transmit queue stall
under the following conditions:
- one CPU bursts ring->size worth of traffic (up to 256 buffers), to the
point where we run out of free descriptors, so we stop the transmit
queue at the end of bcm_sysport_xmit()
- because of our locking, we have the transmit process disable
interrupts which means we can be blocking the TX reclamation process
- when TX reclamation finally runs, we will be computing the difference
between ring->c_index (last consumed index by SW) and what the HW
reports through its register
- this register is masked with (ring->size - 1) = 0xff, which will lead
to stripping the upper bits of the index (register is 16-bits wide)
- we will be computing last_tx_cn as 0, which means there is no work to
be done, and we never wake-up the transmit queue, leaving it
permanently disabled
A practical example is e.g: ring->c_index aka last_c_index = 12, we
pushed 256 entries, HW consumer index = 268, we mask it with 0xff = 12,
so last_tx_cn == 0, nothing happens.

[ Upstream commit a069215cf5985f3aa1bba550264907d6bd05c5f7 ]
When unbinding/removing the driver, we will run into the following warnings:
[ 259.655198] fec 400d1000.ethernet: 400d1000.ethernet supply phy not found, using dummy regulator
[ 259.665065] fec 400d1000.ethernet: Unbalanced pm_runtime_enable!
[ 259.672770] fec 400d1000.ethernet (unnamed net_device) (uninitialized): Invalid MAC address: 00:00:00:00:00:00
[ 259.683062] fec 400d1000.ethernet (unnamed net_device) (uninitialized): Using random MAC address: f2:3e:93:b7:29:c1
[ 259.696239] libphy: fec_enet_mii_bus: probed
Avoid these warnings by balancing the runtime PM calls during fec_drv_remove().

[ Upstream commit f9db50691db4a7d860fce985f080bb3fc23a7ede ]
According to AM335x TRM[1] 14.3.6.2, AM437x TRM[2] 15.3.6.2 and
DRA7 TRM[3] 24.11.4.8.7.3.3, in-band mode in EXT_EN(bit18) register is only
available when PHY is configured in RGMII mode with 10Mbps speed. It will
cause some networking issues without RGMII mode, such as carrier sense
errors and low throughput. TI also mentioned this issue in their forum[4].
This patch adds the check mechanism for PHY interface with RGMII interface
type, the in-band mode can only be set in RGMII mode with 10Mbps speed.
