Driver waits after issuing a reset. When a reset takes too long a driver
gives up. Implemented by invoking PF reset in a loop. After defined
number of unsuccessful PF reset trials it returns error.
Without this patch PF reset fails when NIC is in recovery mode.
So make i40e_set_mac_type() public. i40e driver requires i40e_set_mac_type()
to be public. It is required for recovery mode handling. Without this patch
recovery mode could not be detected in i40e_probe().

Add update to the VSI pointer passed to the i40e_set_vf_mac function.
If VF is in reset state the driver waits in i40e_set_vf_mac function
for the reset to be complete, yet after reset the vsi pointer
that was passed into this function is no longer valid.
The patch updates local VSI pointer directly from pf->vsi array,
by using the id stored in VF pointer (lan_vsi_idx).
Without this commit the driver might occasionally invoke general

When building with gcc, the inlining does not happen, but i40e_set_fc()
calls i40e_aq_get_phy_abilities_resp() anyway, so they add up on the
kernel stack just as much.
The parts that actually use large stacks don't overlap, so make sure
each one is a separate function, and mark them as noinline_for_stack to
prevent the compilers from combining them again.

HV VHCA is a layer which provides PF to VF communication channel based on
HyperV PCI config channel. It implements Mellanox's Inter VHCA control
communication protocol. The protocol contains control block in order to
pass messages between the PF and VF drivers, and data blocks in order to
pass actual data.
The infrastructure is agent based. Each agent will be responsible of
contiguous buffer blocks in the VHCA config space. This infrastructure will
bind agents to their blocks, and those agents can only access read/write
the buffer blocks assigned to them. Each agent will provide three
callbacks (control, invalidate, cleanup). Control will be invoked when
block-0 is invalidated with a command that concerns this agent. Invalidate
callback will be invoked if one of the blocks assigned to this agent was
invalidated. Cleanup will be invoked before the agent is being freed in
order to clean all of its open resources or deferred works.
Block-0 serves as the control block. All execution commands from the PF
will be written by the PF over this block. VF will ack on those by
writing on block-0 as well. Its format is described by struct
mlx5_hv_vhca_control_block layout.

Windows SR-IOV provides a backchannel mechanism in software for communication
between a VF driver and a PF driver. These "configuration blocks" are
similar in concept to PCI configuration space, but instead of doing reads and
writes in 32-bit chunks through a very slow path, packets of up to 128 bytes
can be sent or received asynchronously.
Nearly every SR-IOV device contains just such a communications channel in
hardware, so using this one in software is usually optional. Using the
software channel, however, allows driver implementers to leverage software
tools that fuzz the communications channel looking for vulnerabilities.
The usage model for these packets puts the responsibility for reading or
writing on the VF driver. The VF driver sends a read or a write packet,
indicating which "block" is being referred to by number.
If the PF driver wishes to initiate communication, it can "invalidate" one or
more of the first 64 blocks. This invalidation is delivered via a callback
supplied by the VF driver by this driver.
No protocol is implied, except that supplied by the PF and VF drivers.

This series includes updates to mlx5 ethernet and core driver:
Vlad submits part 3 of 3 part series to allow TC flow handling
for concurrent execution.
Vlad says:
==========
Structure mlx5e_neigh_hash_entry code that uses it are refactored in
following ways:
- Extend neigh_hash_entry with rcu and modify its users to always take
reference to the structure when using it (neigh_hash_entry has already
had atomic reference counter which was only used when scheduling neigh
update on workqueue from atomic context of neigh update netevent).
- Always use mlx5e_neigh_update_table->encap_lock when modifying neigh
update hash table and list. Originally, this lock was only used to
synchronize with netevent handler function, which is called from bh
context and cannot use rtnl lock for synchronization. Use rcu read lock
instead of encap_lock to lookup nhe in atomic context of netevent even
handler function. Convert encap_lock to mutex to allow creating new
neigh hash entries while holding it, which is safe to do because the
lock is no longer used in atomic context.
- Rcu-ify mlx5e_neigh_hash_entry->encap_list by changing operations on
encap list to their rcu counterparts and extending encap structure
with rcu_head to free the encap instances after rcu grace period. This
allows fast traversal of list of encaps attached to nhe under rcu read
lock protection.
- Take encap_table_lock when accessing encap entries in neigh update and
neigh stats update code to protect from concurrent encap entry
insertion or removal.
This approach leads to potential race condition when neigh update and
neigh stats update code can access encap and flow entries that are not
fully initialized or are being destroyed, or neigh can change state
without updating encaps that are created concurrently. Prevent these
issues by following changes in flow and encap initialization:
- Extend mlx5e_tc_flow with 'init_done' completion. Modify neigh update
to wait for both encap and flow completions to prevent concurrent
access to a structure that is being initialized by tc.
- Skip structures that failed during initialization: encaps with
encap_id<0 and flows that don't have OFFLOADED flag set.
- To ensure that no new flows are added to encap when it is being
accessed by neigh update or neigh stats update, take encap_table_lock
mutex.
- To prevent concurrent deletion by tc, ensure that neigh update and
neigh stats update hold references to encap and flow instances while
using them.
With changes presented in this patch set it is now safe to execute tc
concurrently with neigh update and neigh stats update. However, these
two workqueue tasks modify same flow "tmp_list" field to store flows
with reference taken in temporary list to release the references after
update operation finishes and should not be executed concurrently with
each other.
Last 3 patches of this series provide 3 new mlx5 trace points to track
mlx5 tc requests and mlx5 neigh updates.

In order to remove dependency on rtnl lock and allow neigh update workqueue
task to execute concurrently with tc, refactor mlx5e_rep_neigh_update() for
concurrent execution:
- Lock encap table when accessing encap entry to prevent concurrent
changes. To do this properly, the initial encap state check is moved from
mlx5e_rep_neigh_update() into mlx5e_rep_update_flows() to be performed
under encap_tbl_lock protection.
- Wait for encap to be fully initialized before accessing it by means of
'res_ready' completion.
- Add mlx5e_take_all_encap_flows() helper which is used to construct a
temporary list of flows and efi indexes that is used to access current
encap data in flow which can be attached to multiple encaps
simultaneously. Release the flows from temporary list after
encap_tbl_lock critical section. This is necessary because
mlx5e_flow_put() can't be called while holding encap_tbl_lock.
- Modify mlx5e_tc_encap_flows_add() and mlx5e_tc_encap_flows_del() to work

instead of traversing encap flow list directly.

Neigh entry has reference counter, however it is only used when scheduling
neigh update event. In all other cases reference to neigh entry is not
taken while working with it. Neigh code relies on synchronization provided
by rtnl lock and uses encap list size as implicit reference counter.
To remove dependency on rtnl lock, always take reference to neigh entry
while using it. Remove neigh entry from hash table and delete it only when
reference counter reaches zero. This can result spurious neigh update
events, when there is an event on entry that has zero encaps attached.
However, such events are rare and properly handled by neigh update handler.
Extend encap entry with reference to neigh hash entry in order to be able
to directly release it when encap is detached, instead of lookup nhe by key
through hash table. Extend nhe with reference to device priv structure to
guarantee correctness when nhe is used with stack devices, bond setup, in
which case it is non-trivial to determine correct device when releasing the
nhe.

====================
mlxsw: Add devlink-trap support
This patchset adds devlink-trap support in mlxsw.
Patches #1-#4 add the necessary APIs and defines in mlxsw.
Patch #5 implements devlink-trap support for layer 2 drops. More drops
will be added in the future.
Patches #6-#7 add selftests to make sure that all the new code paths are
exercised and that the feature is working as expected.
