63158f916f i40e/i40evf: remove chatty reset messages
Both the PF side and the VF side of the VF reset process are too noisy.
We already warn the user that a reset is happening, and that is
sufficient.

Because some of these message are inside if statements, we have to
rejigger the brackets at the same time to keep our coding style
consistent.

c2451d7f55 i40e/i40evf: fix rx descriptor status
As reported by Eric Dumazet, the driver is not masking the right

This patch extends the mask to allow for the right bits to be

7e612411e7 i40e: relax the firmware API version check
As long as the Firmware isn't reporting a higher API major version number
than what the driver knows about, the driver does not need to worry as
much about greater minor numbers.  The API changes minor numbers when
things get added to the API, but no existing structs or calls are changed.
The driver has the option of warning that the minor numbers don't match.

This will allow a little more flexibility in handling newer NICs and NVMs
in the field.

e7046ee1f8 i40e: Tx/Rx rings declaration
This patch changes the declaration of Tx/Rx rings inside several loops. It
eliminates declaring the same rings every time for the duration of the loop,
instead declaring them once before the loop.

dac9b31a18 i40evf: don't round Tx rate down to 0
Because the hardware configures VF Tx rates in increments of 50 Mbps,
values smaller than that would be rounded down to 0, which was
interpreted as no limit at all. Rather than do this, we round up to 50
Mbps and notify the user.

====================
Intel Wired LAN Driver Updates

This series contains updates to igb, igbvf, ixgbe, i40e and i40evf.

Jacob provides eight patches to cleanup the ixgbe driver to resolve various
checkpatch.pl warnings/errors as well as minor coding style issues.

Stephen Hemminger and I provide simple cleanups of void functions which
had useless return statements at the end of the function which are not
needed.

v2: Dropped Emil's patch "ixgbe: fix the detection of SFP+ capable interfaces"
    while I wait for his updated patch to be validated.

ed616689a3 net-next:v4: Add support to configure SR-IOV VF minimum and maximum Tx rate through ip tool.
o min_tx_rate puts lower limit on the VF bandwidth. VF is guaranteed
  to have a bandwidth of at least this value.
  max_tx_rate puts cap on the VF bandwidth. VF can have a bandwidth
  of up to this value.

o A new handler set_vf_rate for attr IFLA_VF_RATE has been introduced
  which takes 4 arguments:
  netdev, VF number, min_tx_rate, max_tx_rate

o ndo_set_vf_rate replaces ndo_set_vf_tx_rate handler.

o Drivers that currently implement ndo_set_vf_tx_rate should now call
  ndo_set_vf_rate instead and reject attempt to set a minimum bandwidth
  greater than 0 for IFLA_VF_TX_RATE when IFLA_VF_RATE is not yet
  implemented by driver.

o If user enters only one of either min_tx_rate or max_tx_rate, then,
  userland should read back the other value from driver and set both
  for IFLA_VF_RATE.
  Drivers that have not yet implemented IFLA_VF_RATE should always
  return min_tx_rate as 0 when read from ip tool.

o If both IFLA_VF_TX_RATE and IFLA_VF_RATE options are specified, then
  IFLA_VF_RATE should override.

o Idea is to have consistent display of rate values to user.

o Usage example: -

  ./ip link set p4p1 vf 0 rate 900

The commit 6c167f582e ("i40e: Refactor and cleanup i40e_open(),
adding i40e_vsi_open()") introduced a new function i40e_vsi_open()
with the regression by a typo. Due to the commit, the wrong error
code would be passed to i40e_open(). Fix this error in
i40e_vsi_open() by turning the macro into a negative value so that
i40e_open() could return the pertinent error code correctly.

The netlink conflict dealt with moving to netlink_capable() and
netlink_ns_capable() in the 'net' tree vs. supporting 'tc' operations
in non-init namespaces.  These were simple transformations from
netlink_capable to netlink_ns_capable.

0672a09183 i40e: Redistribute queue vectors after DCB reconfiguration
The queue vectors are originally distributed among the total
number of queues that are configured for a given VSI. The number
of queues that are configured for a VSI depends on the number of
TCs that are enabled for the VSI at VSI setup/creation time.

But, the total number of queues that are configured for a VSI may
change based on change in the total number of TCs enabled as a
result of change in DCB configuration based on DCBX.

Hence, it is required for the queue vectors to be redistributed
when the total queues that are configured for a given VSI changes.

Without redistributing the vectors the queues that are configured
for the newly enabled TCs may not be able to do any Tx/Rx.

the interrupt-based handler, and will cause spurious warning messages to
be displayed in the kernel log. Since the hardware can properly trigger
an interrupt, we do not need to poll for an available timestamp in a
work queue any more.

cafa1fca9d i40e: fix Timesync Tx interrupt handler code
This patch fixes the PTP Tx timestamp interrupt handler. The original
code misinterpreted the interrupt handler design. We were clearing the
ena_mask bit for the Timesync interrupts. This is done to indicate that
the interrupt will be handled in a scheduled work item (instead of
immediately) and that work item is responsible for re-enabling the
interrupts. However, the Tx timestamp was being handled immediately and
nothing was ever re-enabling it. This resulted in a single interrupt
working for the life of the driver.

This patch fixes the issue by instead clearing the bit from icr0 which
is used to indicate that the interrupt was immediately handled and can
be re-enabled right away. This patch also clears up a related issue due
to writing the PRTTSYN_STAT_0 register, which was unintentionally
clearing the cause bits for Timesync interrupts.

In addition we need to knock the VF offline so that it does not continue

VF.  The VF will cease operation and the administrator will be forced to
unload and reload the VF driver to make it work again.

059dab6965 i40e: fix TCP flag replication for hardware offload
As reported by Eric Dumazet, the i40e driver was allowing the hardware
to replicate the PSH flag on all segments of a TSO operation.

This patch fixes the first/middle/last TCP flags settings which
makes the TSO operations work correctly.

With this change we are now configuring the CWR bit to only be set
in the first packet of a TSO, so this patch also enables TSO_ECN,
in order to advertise to the stack that we do the right thing
on the wire.

The conversion brings some confusion in error checking as whether
against DMA_BIT_MASK(64) or DMA_BIT_MASK(32). For one, if error is
zero, the check will be against DMA_BIT_MASK(64) twice. Fix this
error checking by binding the check to the pertinent one.

the VF devices. This can be used to deny naughty VF drivers access to
the wire, or to allow VFs (regardless of temperament) to communicate
with each other over the device's internal switch even though external
link is down.

Add the actual ndo function, and modify vc_notify_link_state to check
the link status of each VF before sending a message in the case when
physical link changes state.

206812b5fc i40e/i40evf: i40e implementation for skb_set_hash
Original comment from Tom Herbert <therbert@google.com>

   Drivers should call skb_set_hash to set the hash and its type
   in an skbuff.

This patch builds upon Tom's original implementation and adds
the L4 type return when we know it is an L4 hash.
This requires use of the ptype decoder ring, so enable it.

6c5ef6209d i40e: tighten up ring enable/disable flow
Change the do/while to a for loop, so we don't hit the delay each

Don't bother to set or clear the QENA_STAT bit as it is

pci_enable_msix() and pci_enable_msi_block() all drivers
using these two interfaces need to be updated to use the
new pci_enable_msi_range() and pci_enable_msix_range()
interfaces.

Set the DOWN flag before attempting to disable VFs when unloading the
driver. Also, don't attempt to reset the VFs when the driver is
unloading, because the switch configuration will fail. This fixes a
panic on unload when VFs are enabled.
