nfp: add NFP5000 support
This series broadly speaking adds support for NFP5000 and
related products.
First we add support for loading FW from flash. We need to allow
for the management processor to provide extended log messages when
FW is loaded. This is needed when FW selection policy is to compare
the FW on the disk and in the flash, and load the newer. User should
be told what FW was selected.
We use this opportunity to add extended errors for normal FW loading
as well.
Next we add support for requesting HW information from the management
processor. Up until now the driver read the HWinfo as it appears in
card memory, but there can be cases when management processor has
additional information or generates the entries dynamically so
occasionally we will have to consult it. We use this to look up MAC
addresses for PCIe netdevs.
Next the actual patch with NFP5000 support and a small dose of
refactoring of PCIe init.
The remaining patches add support for reading RTsymbol types we
didn't need before. Ones explicitly placed in external memory unit's
cache and absolute ones.
This part begins with a patch moving the logic which figures out
the correct bit offsets to device probe, to avoid redoing the
calculation for each access. Second patch adds error messages
for easier troubleshooting. Next patch adds helpers which will
take care of address conversions to reach into EMU cache.
Subsequently users are migrated from the raw CPP API to the new RTsym
helpers. Finally we add support for reading absolute symbols.

To enable easier FW distribution NFP can now automatically

If FW loading policy is set to auto it will compare the
versions of FW from the host and from the flash and load
the newer one. If FW type doesn't match (e.g. one advanced
application vs another) the FW from the host takes precedence,
unless one of them is the basic NIC firmware, in which case
the non-basic-NIC FW is selected.

100GbE Intel Wired LAN Driver Updates 2018-08-28
This series contains new features and implementation updates for the
ice driver.
Anirudh reworks the current flex programming logic to add support for
a second flex descriptor profile. Updated the transmit scheduler
code to handle changes to the spec, specifically the firmware expects
a 4KB buffer at all times so fix the default scheduler topology buffer
size. Also the maximum children per node per layer is replaced by
maximum sibling group size. Adds a check to ensure a reset is not in
progress before exercising a control queue operation. Refactored the
switch rule management functions and structures to simply the logic and
to add a common function to search for a rule entry and add a new rule
entry. Refactored the VSI allocation, deletion and rebuild flow so that
on reset we can restore all the filters that were previously added. Did
some spring cleaning of define names and macros.
Dan updates the admin queue command for requesting resource ownership
to the latest specification by adding new enum's and change the locks.
Zhenning optimizes the driver by using the existing buffer in a
structure directly versus a local array.

10GbE Intel Wired LAN Driver Updates 2018-08-28
This series contains updates to ixgbe and ixgbevf only.
Sebastian adds support for firmware NVM recovery mode, which logs a
message when errors are detected and un-registers the device. Also
fixed RSS type recognition with VF to VF communication.
Shannon Nelson implements IPsec hardware offload for VF devices in
Intel's 10GbE x540 family of Ethernet devices.
The IPsec HW offload feature has been in the x540/Niantic family of
network devices since their release in 2009, but there was no Linux
kernel support for the offload until 2017. After the XFRM code added
support for the offload last year, the HW offload was added to the ixgbe
PF driver.
Since the related x540 VF device uses same setup as the PF for implementing
the offload, adding the feature to the ixgbevf seemed like a good idea.
In this case, the PF owns the device registers, so the VF simply packages
up the request information into a VF<->PF message and the PF does the
device configuration.

There seems to be a problem in the x540's internal switch wherein if SR-IOV
mode is enabled and an offloaded IPsec packet is sent to a local VF,
the packet is silently dropped. This might never be a problem as it is
somewhat a corner case, but if someone happens to be using IPsec offload
from the PF to a VF that just happens to get migrated to the local box,
communication will mysteriously fail.
Not good.
A simple way to protect from this is to simply not allow any IPsec offloads
for outgoing packets when num_vfs != 0. This doesn't help any offloads that
were created before SR-IOV was enabled, but we'll get to that later.

VLAN pruning is not valid when VLAN 0 is not active. If VLAN
pruning is enabled and VLAN 0 is not active (8021q driver not loaded)
then normal, non-VLAN, traffic will not pass.
TX/RX VLAN pruning is enabled when the VLAN 0 is added to the
active_vlan bitmap and it is disabled when VLAN 0 is removed from the
active_vlan bitmap.
So, only enable VLAN pruning when VLAN 0 is active. Setting RX VLAN
pruning causes the switch to drop received VLAN packets when there
are no matching VLAN ids in the associated VSI's switch filters. Setting
TX pruning makes it so the switch will not send out any packets with
VLAN tags that don't match the associated VSI's switch filters.
With this patch, if the VF or PF tries to send a VLAN tagged packet with
a VLAN tag that it does not have a pruning rule for it will trigger an
MDD event. For example, if PF0 has VLAN10 and VLAN11 interfaces and
scapy is used to send a packet with VLAN8 then the MDD is triggered.
Also make ice_vsi_kill_vlan return a value which the caller can check
before updating VLAN related data structures (counts, pruning bits, etc.).

When a malicious operation is detected, the firmware triggers an
interrupt, which is then picked up by the service task (specifically by
ice_handle_mdd_event). A reset is scheduled if required.
Tx hang detection works in a similar way, except the logic here monitors
the VSI's Tx queues and tries to revive them if stalled. If the hang is
not resolved, the kernel eventually calls ndo_tx_timeout, which is
handled by ice_tx_timeout.

This patch refactors aspects of the VSI allocation, deletion and rebuild
flow. Some of the more noteworthy changes are described below.
1) On reset, all switch filters applied in the hardware are lost. In
the rebuild flow, only MAC and broadcast filters are being restored.
Instead, use a new function ice_replay_all_fltr to restore all the
filters that were previously added. To do this, remove calls to
ice_remove_vsi_fltr to prevent cleaning out the internal bookkeeping
structures that ice_replay_all_fltr uses to replay filters.
2) Introduce a new state bit __ICE_PREPARED_FOR_RESET to distinguish the
PF that requested the reset (and consequently prepared for it) from
the rest of the PFs. These other PFs will prepare for reset only
when they receive an interrupt from the firmware.
3) Use new functions ice_add_vsi and ice_free_vsi to create and destroy
VSIs respectively. These functions accept a handle to uniquely
identify a VSI. This same handle is required to rebuild the VSI post
reset. To prevent confusion, the existing ice_vsi_add was renamed to
ice_vsi_init.
4) Enhance ice_vsi_setup for the upcoming SR-IOV changes and expose a
new wrapper function ice_pf_vsi_setup to create PF VSIs. Rework the
error handling path in ice_setup_pf_sw.
5) Introduce a new function ice_vsi_release_all to release all PF VSIs.

Once reset is issued, the driver loses all control queue interfaces.
Exercising control queue operations during reset is incorrect and
may result in long timeouts.
This patch introduces a new field 'reset_ongoing' in the hw structure.
This is set to 1 by the core driver when it receives a reset interrupt.
ice_sq_send_cmd checks reset_ongoing before actually issuing the control
queue operation. If a reset is in progress, it returns a soft error code
(ICE_ERR_RESET_PENDING) to the caller. The caller may or may not have to
take any action based on this return. Once the driver knows that the
reset is done, it has to set reset_ongoing back to 0. This will allow
control queue operations to be posted to the hardware again.
This "bail out" logic was specifically added to ice_sq_send_cmd (which
is pretty low level function) so that we have one solution in one place
that applies to all types of control queues.
