If bios sets up an MST output and hardware state readout code sees this is
an SST configuration, when disabling the encoder we end up calling
->post_disable_dp() hook instead of the MST version. Consequently, we write
to the DP_SET_POWER dpcd to set it D3 state. Further along when we try
enable the encoder in MST mode, POWER_UP_PHY transaction fails to power up
the MST hub. This results in continuous link training failures which keep
the system busy delaying boot. We could identify bios MST boot discrepancy
and handle it accordingly but a simple way to solve this is to write to the
DP_SET_POWER dpcd for MST too.

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.

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.

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.

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

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.

Pull libnvdimm fixes from Dan Williams:
"Two regression fixes, two bug fixes for older issues, two fixes for
new functionality added this cycle that have userspace ABI concerns,
and a small cleanup. These have appeared in a linux-next release and
have a build success report from the 0day robot.
* The 4.16 rework of altmap handling led to some configurations
leaking page table allocations due to freeing from the altmap
reservation rather than the page allocator.
The impact without the fix is leaked memory and a WARN() message
when tearing down libnvdimm namespaces. The rework also missed a
place where error handling code needed to be removed that can lead
to a crash if devm_memremap_pages() fails.
* acpi_map_pxm_to_node() had a latent bug whereby it could
misidentify the closest online node to a given proximity domain.
* Block integrity handling was reworked several kernels back to allow
calling add_disk() after setting up the integrity profile.
The nd_btt and nd_blk drivers are just now catching up to fix
automatic partition detection at driver load time.
* The new peristence_domain attribute, a platform indicator of
whether cpu caches are powerfail protected for example, is meant to
be a single value enum and not a set of flags.
This oversight was caught while reviewing new userspace code in
libndctl to communicate the attribute.
Fix this new enabling up so that we are not stuck with an unwanted
userspace ABI"

Pull ACPI fixes from Rafael Wysocki:
"These revert one recent commit that added incorrect battery quirks for
some Asus systems and fix an off-by-one error in the watchdog driver
based on the ACPI WDAT table.
Specifics:
- Revert the recent change adding battery quirks for Asus GL502VSK
and UX305LA as these quirks turn out to be inadequate and possibly
premature (Daniel Drake).
- Fix an off-by-one error in the resource allocation part of the
watchdog driver based on the ACPI WDAT table (Takashi Iwai)"
