The dynamic algorithm, while now working, doesn't have good
performance in 40G mode.
One part of this patch addresses the high CPU utilization of some small
streaming workloads that the driver should reduce CPU in.
It also changes the minimum ITR that the dynamic algorithm
will settle on, causing our minimum latency to go from 12us
to about 14us, when using adaptive mode.
It also changes the BULK interrupt rate to allow maximum throughput
on a 40Gb connection with a single thread of transmit, clamping
interrupt rate to 8000 for TX makes single thread traffic go too
slow.
The new ULTRA bulk setting is introduced and is used
when the Rx packet rate on this queue exceeds 40000 packets per
second. This value of 40000 was chosen because the automatic tuning
of minimum ITR=20us means that a single queue can't quite achieve
that many packets per second from a round-robin test.

With 64 VFs, we can easily overwhelm the AQ on the PF if we have too low
a limit on the number of AQ requests. This leads to ARQ overflow errors,
and occasionally VFs that fail to initialize.
Since we really only hit this condition on initial VF driver load, the
requests that we process are lightweight, so this extra work doesn't
cause problems for the PF driver.

On some devices, in some systems, in some configurations, the VFs would
fail to initialize the first time you loaded the driver.
To correct this, increase the delay time for the init task slightly, and
wait longer before giving up.
If we enable VFs and load the VF driver in the same kernel as the PF
driver, we can totally overwhelm the PF driver with AQ requests because
all of the instances try to initialize at the same time.
To help alleviate this, stagger the initial scheduling of the init task
using the PCIe function as a multiplier. We mask off the function to
only three bits so no instance has to wait too long.
With these two changes, initializing 128 VFs on a single device goes
from four minutes to just a few seconds.

The vlan_features field was correctly being set to the same value as the
netdev features field. However, this was being done before the features
were actually being set up, leaving the vlan_features empty.
Also, after a reset, vlan_features will be incorrectly assigned the
previous netdev feature flags, which can contain VLAN feature bits. This
makes the VLAN code angry and will cause a stack dump.
To fix these issues, set up the netdev features first, then mask out the
VLAN feature bits when assigning vlan_features.

The XL710 hardware has a different interrupt moderation design
that can support a limit of total interrupts per second per
vector, in addition to the "number of interrupts per second"
controls already established in the driver. This combination
of hardware features allows us to set very low default latency
settings but minimize the total CPU utilization by not
making too many interrupts, should the user desire.
The current driver implementation is still enabling the dynamic
moderation in the driver, and only using the rx/tx-usecs
limit in ethtool to limit the interrupt rate per second, by default.
The new code implemented in this patch
2) adds init/use of the new "Interrupt Limit" register
3) adds ethtool knob to control/report the limits above
Usage is ethtool -C ethx rx-usecs-high <value> Where <value> is number
of microseconds to create a rate of 1/N interrupts per second,
regardless of rx-usecs or tx-usecs values. Since there is a credit based
scheme in the hardware, the rx-usecs and tx-usecs can be configured for
very low latency for short bursts, but once the credit runs out the
refill rate on the credits is limited by rx-usecs-high.

Allow the nvmupdate application to decide when a read or write error
should be exposed to the user. Since the application needs to use
write probes to find the ReadOnly sections on a potentially unknown NVM
version in the HW and read probes to check the status of the last write,
some error messages are expected, but need not be shown to the users.
The driver doesn't know which are ignorable from real errors, so needs
to let the application make the decision.

The code in i40e and i40evf is using an "IN_NETPOLL" flag that has never
added any value due to the fact that the Rx clean-up is handled in NAPI.
As such the flag was set, the queue was scheduled via NAPI, and then polled
from the netpoll controller and if any Rx packets were processed the were
processed in the wrong context.
In addition the flag itself just added an unneeded conditional to the
hot-path so it can safely be dropped and save us a few instructions.

The polling routine for i40e was rounding up the budget for Rx cleanup to

Shorten up the delays in the init task, allowing the VF driver to
initialize faster. This aids performance in load/unload tests and
mitigates DMAR errors in VF enable/disable tests with absurdly short
delays. In the real world, the VF driver will come up more quickly.
The original values were set conservatively based on what we expected
from the firmware in terms of performance. Now that the driver is in use
and we know how well firmware responds to our requests, we can shorten
these delays.

Use the phy_types variable to determine what phy types are possible
when link is down instead of device id as it will be more accurate.
When on a backplane device, we do not support changing any settings,
however we should display all the phy_types we are capable of so if we

in place of get_link_info so that the module_types variable stays
up-to-date with the rest of the link information.
The EAS table does not reflect the values that are actually returned,
so instead, basing these values on the Ethernet compliance codes

In some circumstances, the firmware may fail to allocate a VSI for a VF.
When this happens, the driver does not react well to the bad news and
has a panic attack.
To fix this problem, check the return value from i40e_alloc_vf_res and
don't try to configure the device further if it failed. Additionally,
explicitly clear the INIT bit when we free VF resources, so that this
bit will be in the proper state in the failure case, and won't blow up
elsewhere.

Using VFGEN_RSTAT to detect a VF reset is an endeavor that is fraught
with peril. It's entirely too easy to miss a reset because none of the
bits are sticky. By the time the VF driver reads the register, the reset
may have been processed and cleaned up by the PF driver, leaving the
register in the same state that it was before the reset.
Instead, detect a reset with the VF_ARQLEN register. When the VF is
reset, the enable bit in this register is cleared, and it stays cleared
until the VF driver processes the reset and re-enables the admin queue.
Because we now deal with multiple registers in the reset and watchdog
tasks, rename the rstat_val variable to reg_val.

Ran into an issue where PF's VSI type list was different from VF's,
which was resulted in different enum index. The VSI type list can
be different depending on what build flag is used for PF and VF.
The change is to explicitly assign enum index for each VSI type
so that PF and VF always reference to the same VSI type event if the
enum lists are different.

debugging link issues. This patch enables switching it off and on
through an ethtool private flag. The link poll remains on by default,
but can be turned off with
ethtool --set-priv-flags p261p1 LinkPolling off
and later turned back on with
ethtool --set-priv-flags p261p1 LinkPolling on

actually changed.

This patch fixes a problem where the PF's fdir filter table would have an
entry that the hw was unable to add. This notification happens in the hot
path, so instead of trying to fix it then, we note the location in the
failure case and delete it during regular fdir subtask callback. Without
this patch, a case can occur where an invalid entry gets replayed and a
valid one is not.

Under certain circumstances, the device may not have enough resources to
enable all of the VFs that it advertises in config space. Although the
number of supported VFs is reported upon driver init, it is not obvious
when this is different from the number reported in config space. To
eliminate this confusion, add an error message explaining the problem.
Additionally, move the 'Allocating VFs' message down below the error
checks so as to prevent further confusion.

When using something like "ip maddr add ..." to add another unicast mac
address to the netdev, the mac address comes into the set_rx_mode handler
in the multicast list whether it is a unicast or multicast address.
This was confusing the code when it was trying to search for addresses
that needed to be deleted from the VSI, because it was looking for the
VSI unicast address in the netdev unicast list. The result was that a
new unicast address would get added to the VSI list and then immediately
removed, and would never actually make it down into the hardware.
This patch removes the separation from unicast and multicast in the search
for filters to be deleted. It also simplifies the logic a little with a
jump to the bottom of the loop when an address is found. Now it doesn't
matter which netdev list the address is hiding in, we'll check them all.

Previously, the driver could call this function and have only true/false
returned, but false could mean multiple things like failure to read
or link was down. This change allows the caller to get all return values
in the call chain bubbled back to the source, which keeps information about
failures from being lost.
Also, in some unlikely scenarios, the firmware can become slow to respond
to admin queue (AQ) queries for link state. Should the AQ time out,
the driver can detect the state and avoid a link change when there
may have been none.
