Add support for inserting and deleting Rx flow classification
rules through ethtool.
We support classification based on some header fields for
flow-types ether, ip4, tcp4, udp4 and sctp4.
Rx queues are core affine, so the action argument effectively
selects on which cpu the matching frame will be processed.
Discarding the frame is also supported.

For firmware versions that support it, configure an Rx flow
classification key at probe time.
Hardware expects all rules in the classification table to share
the same key. So we setup a key containing all supported fields
at driver init and when a user adds classification rules through
ethtool, we will just mask out the unused header fields.
Since the key composition process is the same for flow
classification and hashing, reuse existing code where possible.

The Management Complex (MC) firmware initially allowed the
configuration of a single key to be used both for Rx flow hashing
and flow classification. This prevented us from supporting
Rx flow classification through ethtool.
Starting with version 10.7.0, the Management Complex(MC) offers
a new set of APIs for separate configuration of Rx hashing and
classification keys.
Update the Rx flow hashing support to use the new API, if available.

The AON_PM_L2 is normally used to trigger and identify the source of a
wake-up event. Since the RX_SYS clock is no longer turned off, we also
have an interrupt being sent to the SYSTEMPORT INTRL_2_0 controller, and
that interrupt remains active up until the magic packet detector is
disabled which happens much later during the driver resumption.
The race happens if we have a CPU that is entering the SYSTEMPORT
INTRL2_0 handler during resume, and another CPU has managed to clear the
wake-up interrupt during bcm_sysport_resume_from_wol(). In that case, we
have the first CPU stuck in the interrupt handler with an interrupt
cause that has been cleared under its feet, and so we keep returning
IRQ_NONE and we never make any progress.
This was not a problem before because we would always turn off the
RX_SYS clock during WoL, so the SYSTEMPORT INTRL2_0 would also be turned
off as well, thus not latching the interrupt.
The fix is to make sure we do not enable either the MPD or
BRCM_TAG_MATCH interrupts since those are redundant with what the
AON_PM_L2 interrupt controller already processes and they would cause
such a race to occur.

RX queue config for bonding master could be different from its slave
device(s). With the commit 6a9e461f6fe4 ("bonding: pass link-local
packets to bonding master also."), the packet is reinjected into stack
with skb->dev as bonding master. This potentially triggers the

"bondX received packet on queue Y, but number of RX queues is Z"
whenever the queue that packet is received on is higher than the
numrxqueues on bonding master (Y > Z).

100GbE Intel Wired LAN Driver Updates 2018-10-02
This series contains updates to ice driver only.
Anirudh expands the use of VSI handles across the rest of the driver,
which includes refactoring the code to correctly use VSI handles. After
a reset, ensure that all configurations for a VSI get re-applied before
moving on to rebuilding the next VSI.
Dave fixed the driver to check the current link state after reset to
ensure that the correct link state of a port is reported. Fixed an
issue where if the driver is unloaded when traffic is in progress,
errors are generated.
Preethi breaks up the IRQ tracker into a software and hardware IRQ
tracker, where the software IRQ tracker tracks only the PF's IRQ
requests and does not play any role in the VF initialization. The
hardware IRQ tracker represents the device's interrupt space and will be
looked up to see if the device has run our of interrupts when a
interrupt has to be allocated in the device for either PF or VF.
Md Fahad adds support for enabling/disabling RSS via ethtool.
Brett aligns the ice_reset_req enum values to the values that the
hardware understands. Also added initial support for dynamic interrupt
moderation in the ice driver.

Currently there is no support for dynamic interrupt moderation. This
patch adds some initial code to support this. The following changes
were made:
1. Currently we are using multiple members to store the interrupt
granularity (itr_gran_25/50/100/200). This is not necessary because
we can query the device to determine what the interrupt granularity
should be set to, done by a new function ice_get_itr_intrl_gran.
2. Added intrl to ice_q_vector structure to support interrupt rate
limiting.
3. Added the function ice_intrl_usecs_to_reg for converting to a value
in usecs that the device understands.
4. Added call to write to the GLINT_RATE register. Disable intrl by
default for now.
5. Changed rx/tx_itr_setting to itr_setting because having both seems
redundant because a ring is either Tx or Rx.
6. Initialize itr_setting for both Tx/Rx rings in ice_vsi_alloc_rings()

This patch implements ethtool hook for enabling/disabling
RSS. While disabling RSS, the LUT should be cleared. And
the LUT should be reconfigured while enabling RSS.

For the PF driver, when mapping interrupts to queues, we need to request
IRQs from the kernel and we also have to allocate interrupts from
the device.
Similarly, when the VF driver (iavf.ko) initializes, it requests the kernel
IRQs that it needs but it can't directly allocate interrupts in the device.
Instead, it sends a mailbox message to the ice driver, which then allocates
interrupts in the device on the VF driver's behalf.
Currently both these cases end up having to reserve entries in
pf->irq_tracker but irq_tracker itself is sized based on how many vectors
the PF driver needs. Under the right circumstances, the VF driver can fail
to get entries in irq_tracker, which will result in the VF driver failing
probe.
To fix this, sw_irq_tracker and hw_irq_tracker are introduced. The
sw_irq_tracker tracks only the PF's IRQ request and doesn't play any
role in VF init. hw_irq_tracker represents the device's interrupt space.
When interrupts have to be allocated in the device for either PF or VF,
hw_irq_tracker will be looked up to see if the device has run out of
interrupts.

We are currently replaying the link state of a port after a reset, but
it is possible that the link state of a port can change during the reset
process. So check for the current link state of a port during the rebuild
process of a reset.

Currently, switch filters get replayed after reset. In addition to
filters, other VSI attributes (like RSS configuration, Tx scheduler
configuration, etc.) also need to be replayed after reset.
Thus, instead of replaying based on functional blocks (i.e. replay
all filters for all VSIs, followed by RSS configuration replay for
all VSIs, and so on), it makes more sense to have the replay centered
around a VSI. In other words, replay all configurations for a VSI before
moving on to rebuilding the next VSI.
To that effect, this patch introduces a VSI replay framework in a new
function ice_vsi_replay_all. Currently it only replays switch filters,
but it will be expanded in the future to replay additional VSI attributes.

A VSI handle is just a number the driver maintains to uniquely identify
a VSI. A VSI handle is backed by a VSI number in the hardware. When
interacting when the hardware, VSI handles are converted into VSI numbers.
In commit 0f9d5027a749 ("ice: Refactor VSI allocation, deletion and
rebuild flow"), VSI handles were introduced but it was used only
when creating and deleting VSIs. This patch is part one of two patches
that expands the use of VSI handles across the rest of the driver. Also
in this patch, certain parts of the code had to be refactored to correctly
use VSI handles.

In current ABI the size of the messages carrying map elements was
statically defined to at most 16 words of key and 16 words of value
(NFP word is 4 bytes). We should not make this assumption and use
the max key and value sizes from the BPF capability instead.
To make sure old kernels don't get surprised with larger (or smaller)
messages bump the FW ABI version to 3 when key/value size is different
than 16 words.

Up until now we only had per-vNIC BPF ABI version capabilities,
which are slightly awkward to use because bulk of the resources
and configuration does not relate to any particular vNIC. Add
a new capability for global ABI version and check the per-vNIC
version are equal to it. Assume the ABI version 2 if no explicit
version capability is present.

When choosing channel amounts and ring sizes, the maximums in the
ibmvnic driver are defined by the virtual i/o server management
partition. Even though they are defined as maximums, the client
driver may in fact successfully request resources that exceed
these limits, which are mostly dependent on a user's hardware
With this in mind, provide an ethtool flag that when enabled will
allow the user to request resources limited by driver-defined
maximums instead of limits defined by the management partition.
The driver will try to honor the user's request but may not allowed
by the management partition. In this case, the driver requests
as close as it can get to the desired amount until it succeeds.

Some of the chip-specific hw_start functions set bit TXCFG_AUTO_FIFO
in register TxConfig. The original patch changed the order of some
calls resulting in these changes being overwritten by
rtl_set_tx_config_registers() in rtl_hw_start(). This eventually
resulted in network stalls especially under high load.
Analyzing the chip-specific hw_start functions all chip version from
34, with the exception of version 39, need this bit set.
This patch moves setting this bit to rtl_set_tx_config_registers().

The RSC feature -- a bit field "internal" was added here with total
size unchanged:
struct rndis_per_packet_info {
u32 size;
u32 type:31;
u32 internal:1;
u32 ppi_offset;
};
On TX path, we put rndis msg into skb head room, which is not zeroed
before passing to us. We do not use the "internal" field in TX path,
but it may impact older hosts which use the entire 32 bits as "type".
To fix the bug, this patch sets the field "internal" to zero.
