This patch fixes the problem of the spin locks, originally
meant for the netpoll path of hns driver, causing deadlock in
the normal NAPI poll path. The issue happened due to the presence
of the stray leftover spin lock code related to the netpoll,
whose support was earlier removed from the HNS[1], got activated
due to enabling of NET_POLL_CONTROLLER switch.
Earlier background:
The netpoll handling code originally had this bug(as identified
by Marc Zyngier[2]) of wrong spin lock API being used which did
not disable the interrupts and hence could cause locking issues.
i.e. if the lock were first acquired in context to thread like
'ip' util and this lock if ever got later acquired again in
context to the interrupt context like TX/RX (Interrupts could
always pre-empt the lock holding task and acquire the lock again)
and hence could cause deadlock.
Proposed Solution:
1. If the netpoll was enabled in the HNS driver, which is not
right now, we could have simply used spin_[un]lock_irqsave()
2. But as netpoll is disabled, therefore, it is best to get rid
of the existing locks and stray code for now. This should
solve the problem reported by Marc.

Rework SCHED API to allow offloading TC-MQPRIO QoS configuration.
The existing QUEUE based rate limiting throttles all queues sharing
a traffic class, to the specified max rate limit value. So, if
multiple queues share a traffic class, then all the queues get
the aggregate specified max rate limit.
So, introduce the new FLOWC based rate limiting, where multiple
queues can share a traffic class with each queue getting its own
individual specified max rate limit.
For example, if 2 queues are bound to class 0, which is rate limited
to 1 Gbps, then 2 queues using QUEUE based rate limiting, get the
aggregate output of 1 Gbps only. In FLOWC based rate limiting, each
queue gets its own output of max 1 Gbps each; i.e. 2 queues * 1 Gbps
rate limit = 2 Gbps.

====================
100GbE Intel Wired LAN Driver Updates 2019-11-06
This series contains updates to ice driver only.
Scott adds ethtool -m support so that we can read eeprom data on SFP/OSFP
modules.
Anirudh updates the return value to properly reflect when SRIOV is not
supported.
Md Fahad updates the driver to handle a change in the NVM, where the
boot configuration section was moved to the Preserved Field Area (PFA)
of the NVM.
Paul resolves an issue when DCBx requests non-contiguous TCs, transmit
hangs could occur, so configure a default traffic class (TC0) in these
cases to prevent traffic hangs. Adds a print statement to notify the
user when unsupported modules are inserted.
Bruce fixes up the driver unload code flow to ensure we do not clear the
interrupt scheme until the reset is complete, otherwise a hardware error
may occur.
Dave updates the DCB initialization to set is_sw_lldp boolean when the
firmware has been detected to be in an untenable state. This will
ensure that the firmware is in a known state.
Michal saves off the PCI state and I/O BARs address after PCI bus reset
so that after the reset, device registers can be read. Also adds a NULL
pointer check to prevent a potential kernel panic.
Mitch resolves an issue where VF's on PF's other than 0 were not seeing
resets by using the per-PF VF ID instead of the absolute VF ID.
Krzysztof does some code cleanup to remove a unneeded wrapper and
reduces the code complexity.
Brett reduces confusion by changing the name of ice_vc_dis_vf() to
ice_vc_reset_vf() to better describe what the function is actually
doing.
v2: dropped patch 3 "ice: Add support for FW recovery mode detection"
from the origin al series, while Ani makes changes based on
community feedback to implement devlink into the changes.
v3: dropped patch 1 "ice: implement set_eeprom functionality" due to a
bug found and additional changes will be needed when Ani implements
devlink in the driver.

When using addressing > 32 bits the TSO first descriptor only has the
header so we can't set the payload field for this descriptor. Let's
reset the variable so that buffer 2 value is zero.

Currently, stmmac_rx() is counting the number of descriptors but it
should count the number of packets as specified by the NAPI limit.
Fix this.

MMC interrupts were being enabled, which is not what we want because it
will lead to a storm of interrupts that are not handled at all. Fix it
by disabling all MMC interrupts for XGMAC.

Fix incorrect precedence of operators. For reference: AV implies AV
Feature but RAV implies only RX side AV Feature. As we want full AV

In L2 tests that filter packets by destination MAC address we need to
prevent false positives that can occur if we add an address that
collides with the existing ones.
To fix this, lets manually check if the new address to be added is
already present in the NIC and use a different one if so. For Hash
filtering this also envolves converting the address to the hash.
