Currently when a VSI is built (i.e. reset, set channels, etc.)
the coalesce settings will be preserved in most cases. However, when the
number of q_vectors are increased the settings for the new q_vectors
will be set to the driver defaults of AIM on, Rx/Tx ITR 50, and INTRL 0.
This is causing issues with how the ethtool layer gets the current
coalesce settings since it only uses q_vector 0. So, assume that the user
set the coalesce settings globally (i.e. ethtool -C eth0) and use q_vector
0's settings for all of the new q_vectors.

A VF driver has the ability to request reset via VIRTCHNL_OP_RESET_VF.
This is a required step in VF driver load. Currently, the PF is only
allowing a VF to request reset using this method after the VF has
already communicated resources via VIRTCHNL_OP_GET_VF_RESOURCES.
However, this is incorrect because the VF can request reset before
requesting resources. Fix this by allowing the VF to request a reset
once it has been initialized.

Currently when a VF VSI calls ice_vsi_release() and ice_vsi_setup() it
subsequently clears/sets the VF cached variables for lan_vsi_idx and
lan_vsi_num. This works fine, but can be improved by handling this in
the VF specific VSI release and setup functions.
Also, when a VF VSI is setup too many parameters are passed that can be
derived from the VF. Fix this by only calling VF VSI setup with the bare
minimum parameters.
Also, add functionality to invalidate a VF's VSI when it's released
and/or setup fails. This will make it so a VF VSI cannot be accessed via
its cached vsi_idx/vsi_num in these cases.
Finally when a VF's VSI is invalidated set the lan_vsi_idx and
lan_vsi_num to ICE_NO_VSI to clearly show that there is no valid VSI
associated with this VF.

Currently VF VSI are being reset twice during a PFR or greater. This is
causing reset, specifically resetting all VFs, to take too long. This is
causing various issues with VF drivers not being able to gracefully
handle the VF reset timeout. Fix this by refactoring how VF reset is
handled for the case mentioned previously and for the VFR/VFLR case.
The refactor was done by doing the following:
1. Removing the call to ice_vsi_rebuild_by_type for
ICE_VSI_VF VSI, which was causing the initial VSI rebuild.
2. Adding functions for pre/post VSI rebuild functions that can be called
in both the reset all VFs case and reset individual VF case.
3. Adding VSI rebuild functions that are specific for the reset all VFs
case and adding functions that are specific for the reset individual
VF case.
4. Calling the pre-rebuild function, then the specific VSI rebuild
function based on the reset type, and then calling the post-rebuild
function to handle VF resets.
This patch series makes some assumptions about how VSI are handling by
FW during reset:
1. During a PFR or greater all VSI in FW will be cleared.
2. During a VFR/VFLR the VSI rebuild responsibility is in the hands of
the PF software.
3. There is code in the ice_reset_all_vfs() case to amortize operations
if possible. This was left intact.
4. PF software should not be replaying VSI based filters that were added
other than host configured, PF software configured, or the VF's
default/LAA MAC. This is the VF drivers job after it has been reset.

If a UMEM is present on a queue when an interface/queue pair is being
enabled, the driver will try to prepare the Rx buffers in advance to
improve performance. However, if fill queue is shorter than HW Rx ring,
the driver will report failure after getting the last address from the
fill queue.
This still lets the driver process the packets correctly during the NAPI
poll, but leads to a constant NAPI rescheduling. Not allocating the
buffers in advance would result in a potential performance decrease.
Commit d57d76428ae9 ("xsk: Add API to check for available entries in FQ")
provides an API that lets drivers check the number of addresses that the
fill queue holds.
Notify the user if fill queue is not long enough to prepare all buffers
before packet processing starts, and allocate the buffers during the
NAPI poll. If the fill queue size is sufficient, prepare Rx buffers in
advance.

100GbE Intel Wired LAN Driver Updates 2020-05-22
This series contains updates to virtchnl and the ice driver.
Geert Uytterhoeven fixes a data structure alignment issue in the
virtchnl structures.
Henry adds Flow Director support which allows for the redirection on
ntuple rules over six patches. Initially Henry adds the initial
infrastructure for Flow Director, and then later adds IPv4 and IPv6
support, as well as being able to display the ntuple rules.
Bret add Accelerated Receive Flow Steering (aRFS) support which is used
to steer receive flows to a specific queue. Fixes a transmit timeout
when the VF link transitions from up/down/up because the transmit and
receive queue interrupts are not enabled as part of VF's link up. Fixed
an issue when the default VF LAN address is changed and after reset the
PF will attempt to add the new MAC, which fails because it already
exists. This causes the VF to be disabled completely until it is removed
and enabled via sysfs.
Anirudh (Ani) makes a fix where the ice driver needs to call set_mac_cfg
to enable jumbo frames, so ensure it gets called during initialization
and after reset. Fix bad register reads during a register dump in
ethtool by removing the bad registers.
Paul fixes an issue where the receive Malicious Driver Detection (MDD)
auto reset message was not being logged because it occurred after the VF
reset.
Victor adds a check for compatibility between the Dynamic Device
Personalization (DDP) package and the NIC firmware to ensure that
everything aligns.
