commit f72f2fb8fb6be095b98af5d740ac50cffd0b0cae upstream.
Having multiple destination ports for a unicast address does not make
sense.
Make port_db_load_purge override existent unicast portvec instead of
adding a new port bit.

commit 64f55156f7adedb1ac5bb9cdbcbc9ac05ff5a724 upstream.
If we have only a single RX queue, such as when MSI-X is not
available, we should not send the RFH_QUEUEU_CONFIG_CMD, because our
only queue is the same as the command queue and will be configured as
part of the context info. Our code was actually trying to send the
command with 0 queues, which caused UMAC assert 0x1D04.
Fix that by not sending the command when we have a single queue.

[ Upstream commit cc9f07a838c4988ed244d0907cb71d54b85482a5 ]
So far phy_disconnect() is called before free_irq(). If CONFIG_DEBUG_SHIRQ
is set and interrupt is shared, then free_irq() creates an "artificial"
interrupt by calling the interrupt handler. The "link change" flag is set
in the interrupt status register, causing phylib to eventually call
phy_suspend(). Because the net_device is detached from the PHY already,
the PHY driver can't recognize that WoL is configured and powers down the
PHY.

This reverts commit 2ad1274fa35ace5c6360762ba48d33b63da2396c
VF queues were not brought up when PF was brought up after being
downed if the VF driver disabled VFs queues during PF down.
This could happen in some older or external VF driver implementations.
The problem was that PF driver used vf->queues_enabled as a condition
to decide what link-state it would send out which caused the issue.
Remove the check for vf->queues_enabled in the VF link notify.
Now VF will always be notified of the current link status.
Also remove the queues_enabled member from i40e_vf structure as it is
not used anymore. Otherwise VNF implementation was broken and caused
a link flap.
The original commit was a workaround to avoid breaking existing VFs though
it's really a fault of the VF code not the PF. The commit should be safe to
revert as all of the VFs we know of have been fixed. Also, since we now
know there is a related bug in the workaround, removing it is preferred.

commit f0947d0d21b219e03940b9be6628a43445c0de7a upstream.
Function __team_compute_features() is protected by team->lock
mutex when it is called from team_compute_features() used when
features of an underlying device is changed. This causes
a deadlock when NETDEV_FEAT_CHANGE notifier for underlying device
is fired due to change propagated from team driver (e.g. MTU
change). It's because callbacks like team_change_mtu() or
team_vlan_rx_{add,del}_vid() protect their port list traversal
by team->lock mutex.
Example (r8169 case where this driver disables TSO for certain MTU
values):
...
[ 6391.348202] __mutex_lock.isra.6+0x2d0/0x4a0
[ 6391.358602] team_device_event+0x9d/0x160 [team]
[ 6391.363756] notifier_call_chain+0x47/0x70
[ 6391.368329] netdev_update_features+0x56/0x60
[ 6391.373207] rtl8169_change_mtu+0x14/0x50 [r8169]
[ 6391.378457] dev_set_mtu_ext+0xe1/0x1d0

[ 6391.399963] do_setlink+0x231/0xf50
...
In fact team_compute_features() called from team_device_event()
does not need to be protected by team->lock mutex and rcu_read_lock()
is sufficient there for port list traversal.

[ Upstream commit 329a3678ec69962aa67c91397efbd46d36635f91 ]
Link speed advertising in igc has two problems:
- When setting the advertisement via ethtool, the link speed is converted
to the legacy 32 bit representation for the intel PHY code.
This inadvertently drops ETHTOOL_LINK_MODE_2500baseT_Full_BIT (being
beyond bit 31). As a result, any call to `ethtool -s ...' drops the
2500Mbit/s link speed from the PHY settings. Only reloading the driver
alleviates that problem.
Fix this by converting the ETHTOOL_LINK_MODE_2500baseT_Full_BIT to the
Intel PHY ADVERTISE_2500_FULL bit explicitly.
- Rather than checking the actual PHY setting, the .get_link_ksettings
function always fills link_modes.advertising with all link speeds
the device is capable of.
Fix this by checking the PHY autoneg_advertised settings and report
only the actually advertised speeds up to ethtool.

If we spin for a long time in memory reads that (for some reason in
hardware) take a long time, then we'll eventually get messages such
as
watchdog: BUG: soft lockup - CPU#2 stuck for 24s! [kworker/2:2:272]
This is because the reading really does take a very long time, and
we don't schedule, so we're hogging the CPU with this task, at least
if CONFIG_PREEMPT is not set, e.g. with CONFIG_PREEMPT_VOLUNTARY=y.
Previously I misinterpreted the situation and thought that this was
only going to happen if we had interrupts disabled, and then fixed
this (which is good anyway, however), but that didn't always help;
looking at it again now I realized that the spin unlock will only
reschedule if CONFIG_PREEMPT is used.
In order to avoid this issue, change the code to cond_resched() if
we've been spinning for too long here.

[ Upstream commit b06ca3d5a43ca2dd806f7688a17e8e7e0619a80a ]
Increase critical threshold for ASIC thermal zone from 110C to 140C
according to the system hardware requirements. All the supported ASICs
(Spectrum-1, Spectrum-2, Spectrum-3) could be still operational with ASIC
temperature below 140C. With the old critical threshold value system
can perform unjustified shutdown.
All the systems equipped with the above ASICs implement thermal
protection mechanism at firmware level and firmware could decide to
perform system thermal shutdown in case the temperature is below 140C.
So with the new threshold system will not meltdown, while thermal
operating range will be aligned with hardware abilities.

Validate thresholds to avoid a single failure due to some transceiver
unreliability. Ignore the last readouts in case warning temperature is
above alarm temperature, since it can cause unexpected thermal
shutdown. Stay with the previous values and refresh threshold within
the next iteration.
This is a rare scenario, but it was observed at a customer site.

[ Upstream commit a2bc221b972db91e4be1970e776e98f16aa87904 ]
For all PCI functions on the netxen_nic adapter, interrupt
mode (INTx or MSI) configuration is dependent on what has
been configured by the PCI function zero in the shared
interrupt register, as these adapters do not support mixed
mode interrupts among the functions of a given adapter.
Logic for setting MSI/MSI-x interrupt mode in the shared interrupt
register based on PCI function id zero check is not appropriate for
all family of netxen adapters, as for some of the netxen family
adapters PCI function zero is not really meant to be probed/loaded
in the host but rather just act as a management function on the device,
which caused all the other PCI functions on the adapter to always use
legacy interrupt (INTx) mode instead of choosing MSI/MSI-x interrupt mode.
This patch replaces that check with port number so that for all
type of adapters driver attempts for MSI/MSI-x interrupt modes.

commit 869c4d5eb1e6fbda66aa790c48bdb946d71494a0 upstream.
The function bnxt_get_ulp_stat_ctxs() does not count the stats contexts
used by the RDMA driver correctly when the RDMA driver is freeing the
MSIX vectors. It assumes that if the RDMA driver is registered, the
additional stats contexts will be needed. This is not true when the
RDMA driver is about to unregister and frees the MSIX vectors.
This slight error leads to over accouting of the stats contexts needed
after the RDMA driver has unloaded. This will cause some firmware
warning and error messages in dmesg during subsequent config. changes
or ifdown/ifup.
Fix it by properly accouting for extra stats contexts only if the
RDMA driver is registered and MSIX vectors have been successfully
requested.

[ Upstream commit 887078de2a23689e29d6fa1b75d7cbc544c280be ]
Table 8-53 in the QUICC Engine Reference manual shows definitions of
fields up to a size of 192 bytes, not just 128. But in table 8-111,
one does find the text
Base Address of the Global Transmitter Parameter RAM Page. [...]
The user needs to allocate 128 bytes for this page. The address must
be aligned to the page size.
I've checked both rev. 7 (11/2015) and rev. 9 (05/2018) of the manual;
they both have this inconsistency (and the table numbers are the
same).
Adding a bit of debug printing, on my board the struct
ucc_geth_tx_global_pram is allocated at offset 0x880, while
the (opaque) ucc_geth_thread_data_tx gets allocated immediately
afterwards, at 0x900. So whatever the engine writes into the thread
data overlaps with the tail of the global tx pram (and devmem says
that something does get written during a simple ping).
I haven't observed any failure that could be attributed to this, but
it seems to be the kind of thing that would be extremely hard to
debug. So extend the struct definition so that we do allocate 192
bytes.

commit cb82a54904a99df9e8f9e9d282046055dae5a730 upstream.
This USB-C Hub (17ef:721e) based on the Realtek RTL8153B chip used to
use the cdc_ether driver. However, using this driver, with the system
suspended the device constantly sends pause-frames as soon as the
receive buffer fills up. This causes issues with other devices, where
some Ethernet switches stop forwarding packets altogether.
Using the Realtek driver (r8152) fixes this issue. Pause frames are no
longer sent while the host system is suspended.
