rx_mini_pending was set to an incorrect value. This was causing EINVAL to
always be returned to 'ethtool -G'. The driver does not support mini or
jumbo rings so the respective settings should be zero.
Also, change the valid range of the number of descriptors in the rings to
make the code simpler and easier for users to understand (this removes the
valid settings of 8 and 16). Add a system log message indicating when the
number is rounded-up from what the user specifies with the 'ethtool -G'
command (i.e. when it is not a multiple of 32), and update the log message
when a user-provided value is out of range to also indicate the stride.

We have MAX_FW_API_VER_BRANCH, MAX_FW_API_VER_MAJOR, and
MAX_FW_API_VER_MINOR that we use in ice_controlq.h to test when a
firmware version is newer than expected. This is currently tested by
comparing each field separately. Thus, we compare the branch field
against the MAX_FW_API_VER_BRANCH, and so forth.
This means that currently, if we suppose that the max firmware version
is defined as 0.2.1, i.e.
Then firmware 0.1.3 will fail to load. This is because the minor version
3 is greater than the max minor version 1.
This is not intuitive, because of the notion that increasing the major
firmware version to 2 should mean any firmware version with a major
version is less than 2 should be considered older than 2...
In order to allow both 0.2.1 and 0.1.3 to load, you would have to define
the "max" firmware version as 0.2.3.. It is possible that such
a firmware version doesn't even exist yet!
Fix this by replacing the current logic with an updated check that
behaves as follows:
First, we check the major version. If it is greater than the expected
version, then we prevent driver load. Additionally, a warning message is
logged to indicate to the system administrator that they need to update
their driver. This is now the only case where the driver will refuse to
load.
Second, if the major version is less than the expected version, we log
an information message indicating the NVM should be updated.
Third, if the major version is exact, we'll then check the minor
version. If the minor version is more than two versions less than
expected, we log an information message indicating the NVM should be
updated. If it is more than two versions greater than the expected
version, we log an information message that the driver should be
updated.
To support this, the ice_aq_ver_check function needs its signature
updated to pass the HW structure. Since we now pass this structure,
there is no need to pass the firmware API versions separately.

When shutting down the controlqs, we check if they are initialized
before we shut them down and destroy the lock. This is important, as it
prevents attempts to access the lock of an already shutdown queue.
Unfortunately, we checked rq.head and sq.head as the value to determine
if the queue was initialized. This doesn't work, because head is not
reset when the queue is shutdown. In some flows, the adminq will have
already been shut down prior to calling ice_shutdown_all_ctrlqs. This
can result in a crash due to attempting to access the already destroyed
mutex.
Fix this by using rq.count and sq.count instead. Indeed, ice_shutdown_sq
and ice_shutdown_rq already indicate that this is the value we should be
using to determine of the queue was initialized.

The current netpoll implementation in the bnxt_en driver has problems
that may miss TX completion events. bnxt_poll_work() in effect is
only handling at most 1 TX packet before exiting. In addition,
there may be in flight TX completions that ->poll() may miss even
after we fix bnxt_poll_work() to handle all visible TX completions.
netpoll may not call ->poll() again and HW may not generate IRQ
because the driver does not ARM the IRQ when the budget (0 for netpoll)
is reached.
We fix it by handling all TX completions and to always ARM the IRQ
when we exit ->poll() with 0 budget.
Also, the logic to ACK the completion ring in case it is almost filled
with TX completions need to be adjusted to take care of the 0 budget
case, as discussed with Eric Dumazet <edumazet@google.com>

The mvneta controller can handle speeds up to 2500Mbps on the SGMII
interface. This relies on serdes configuration, the lane must be
configured at 3.125Gbps and we can't use in-band autoneg at that speed.
The main issue when supporting that speed on this particular controller
is that the link partner can send ethernet frames with a shortened
preamble, which if not explicitly enabled in the controller will cause
unexpected behaviours.
This was tested on Armada 385, with the comphy configuration done in

40GbE Intel Wired LAN Driver Updates 2018-09-25
This series contains updates to i40e and xsk.
Mariusz fixes an issue where the VF link state was not being updated
properly when the PF is down or up. Also cleaned up the promiscuous
configuration during a VF reset.
Patryk simplifies the code a bit to use the variables for PF and HW that
are declared, rather than using the VSI pointers. Cleaned up the
message length parameter to several virtchnl functions, since it was not
being used (or needed).
Harshitha fixes two potential race conditions when trying to change VF
settings by creating a helper function to validate that the VF is
enabled and that the VSI is set up.
Sergey corrects a double "link down" message by putting in a check for
whether or not the link is up or going down.
Björn addresses an AF_XDP zero-copy issue that buffers passed
from userspace to the kernel was leaked when the hardware descriptor
ring was torn down. A zero-copy capable driver picks buffers off the
fill ring and places them on the hardware receive ring to be completed at
a later point when DMA is complete. Similar on the transmit side; The
driver picks buffers off the transmit ring and places them on the
transmit hardware ring.
In the typical flow, the receive buffer will be placed onto an receive
ring (completed to the user), and the transmit buffer will be placed on
the completion ring to notify the user that the transfer is done.
However, if the driver needs to tear down the hardware rings for some
reason (interface goes down, reconfiguration and such), the userspace
buffers cannot be leaked. They have to be reused or completed back to
userspace.

When an AF_XDP UMEM is attached to any of the Rx rings, we disallow a
user to change the number of descriptors via e.g. "ethtool -G IFNAME".
Otherwise, the size of the stash/reuse queue can grow unbounded, which
would result in OOM or leaking userspace buffers.

Outstanding Rx descriptors are temporarily stored on a stash/reuse
queue. When/if the HW rings comes up again, entries from the stash are
used to re-populate the ring.
The latter required some restructuring of the allocation scheme for
the AF_XDP zero-copy implementation. There is now a fast, and a slow
allocation. The "fast allocation" is used from the fast-path and
obtains free buffers from the fill ring and the internal recycle
mechanism. The "slow allocation" is only used in ring setup, and
obtains buffers from the fill ring and the stash (if any).

When we are trying to change VF settings, it is possible for 2 race
conditions to happen. One, when the VF is created but not yet enabled.
Second, the VF is enabled but the VSI is still not created or not yet
re-created in the VF reset flow.
This patch introduces a helper function to validate that the VF is
enabled and that the VSI is set up. This patch also calls this
function from other functions which could get into these race conditions.
While we are poking around here, remove unnecessary parenthesis that

Add support for configuring this hash key at runtime.
We support all standard header fields configurable through ethtool,
but cannot differentiate between flow types, so the same hash key
is applied regardless of protocol.
We also don't support the discard option.

With CONFIG_DMA_API_DEBUG enabled we get DMA unmapping warning in
various places of the mvneta driver, for example when putting down an
interface while traffic is passing through.
The issue is when using s/w buffer management, the Rx buffers are mapped
using dma_map_page but unmapped with dma_unmap_single. This patch fixes
this by using the right unmapping function.
