Add routines for manipulating TLS TX offload contexts.

In Innova TLS, TLS contexts are added or deleted
via a command message over the SBU connection.
The HW then sends a response message over the same connection.

Add implementation for Innova TLS (FPGA-based) hardware.

These routines will be used by the TLS offload support in a later patch

mlx5/accel is a middle acceleration layer to allow mlx5e and other ULPs
to work directly with mlx5_core rather than Innova FPGA or other mlx5
acceleration providers.

In the future, when IPSec/TLS or any other acceleration gets integrated
into ConnectX chip, mlx5/accel layer will provide the integrated
acceleration, rather than the Innova one.

When handling mirroring to a gretap or ip6gretap netdevice in mlxsw, the
underlay address (i.e. the remote address of the tunnel) may be routed
to a bridge.

In that case, look up the resolved neighbor Ethernet address in that
bridge's FDB. Then configure the offload to direct the mirrored traffic
to that port, possibly with tagging.

Changes to switchdev artifact can make a SPAN entry offloadable or
unoffloadable. To that end:

- Listen to SWITCHDEV_FDB_*_TO_BRIDGE notifications in addition to
  the *_TO_DEVICE ones, to catch whatever activity is sent to the
  bridge (likely by mlxsw itself).

  On each FDB notification, respin SPAN to reconcile it with the FDB
  changes.

- Also respin on switchdev port attribute changes (which currently
  covers changes to STP state of ports) and port object additions and

queues in the VF VSI. This patch makes sure that happens.

By breaking out the individual queue set up functions so
that they can be called directly from the i40e_virtchnl_pf.c

When operating at 1GbE, the base incval for the PTP clock is so large
that multiplying it by numbers close to the max_adj can overflow the
u64.

Rather than attempting to limit the max_adj to a value small enough to
avoid overflow, instead calculate the incvalue adjustment based on the
40GbE incvalue, and then multiply that by the scaling factor for the
link speed.

This sacrifices a small amount of precision in the adjustment but we
avoid erratic behavior of the clock due to the overflow caused if ppb is
very near the maximum adjustment.

This fixes at least 2 issues I have found with the UDP tunnel filter
configuration.

The first issue is the fact that the tunnels didn't have any sort of mutual
exclusion in place to prevent an update from racing with a user request to
add/remove a port. As such you could request to add and remove a port
before the port update code had a chance to respond which would result in a
very confusing result. To address it I have added 2 changes. First I added
the RTNL mutex wrapper around our updating of the pending, port, and
filter_index bits. Second I added logic so that we cannot use a port that
has a pending deletion since we need to free the space in hardware before
we can allow software to reuse it.

The second issue addressed is the fact that we were not recording the
actual filter index provided to us by the admin queue. As a result we were
deleting filters that were not associated with the actual filter we wanted
to delete. To fix that I added a filter_index member to the UDP port
tracking structure.

i40evf_add_vlan() is never called in atomic context.

i40evf_add_vlan() is only called by i40evf_vlan_rx_add_vid(),
which is only set as ".ndo_vlan_rx_add_vid" in struct net_device_ops.
".ndo_vlan_rx_add_vid" is not called in atomic context.

Despite never getting called from atomic context,
i40evf_add_vlan() calls kzalloc() with GFP_ATOMIC,
which does not sleep for allocation.
GFP_ATOMIC is not necessary and can be replaced with GFP_KERNEL,
which can sleep and improve the possibility of sucessful allocation.

This is found by a static analysis tool named DCNS written by myself.
And I also manually check it.

Currently done:

- if mac_version in (01, 02, 03, 04)
	rtl_set_rx_tx_config_registers(tp);
- if mac_version not in (01, 02, 03, 04)
	RTL_W8(tp, ChipCmd, CmdTxEnb | CmdRxEnb);
	rtl_set_rx_tx_config_registers(tp);

So we do exactly the same independent of chip version and can simplify

reading this register where we could use the cached value.

In addition:
- Properly initialize tp->cmd with the register value.
- In rtl_hw_start_8169 remove one setting of PCIMulRW because it's
  set unconditionally anyway a few lines later.
- In rtl_hw_start_8168 properly mask out the INTT bits before
