Some IIC multifunction devices may have multiple I2C addresses per chip, but

the sub-devices for the secondary addresses must be created manually with
fixed OFW parameters (node, name, compatibility string, IIC address).
Add a bus method to the ofw_iicbus interface that does this.

mlx5en: Implement TLS RX support.

TLS RX support is modeled after TLS TX support. The basic structures and layouts
are almost identical, except that the send tag created filters RX traffic and
not TX traffic.

The TLS RX tag keeps track of past TLS records up to a certain limit,
approximately 1 Gbyte of TCP data. TLS records of same length are joined
into a single database record.

Regularly the HW is queried for TLS RX progress information. The TCP sequence
number gotten from the HW is then matches against the database of TLS TCP
sequence number records and lengths. If a match is found a static params WQE
is queued on the IQ and the hardware should immediately resume decrypting TLS
data until the next non-sequential TCP packet arrives.

Offloading TLS RX data is supported for untagged, prio-tagged, and
regular VLAN traffic.

mlx5en: Implement support for internal queues, IQ.

Internal send queues are regular sendqueues which are reserved for WQE commands
towards the hardware and firmware. These queues typically carry resync
information for ongoing TLS RX connections and when changing schedule queues
for rate limited connections.

The internal queue, IQ, code is more or less a stripped down copy
of the existing SQ managing code with exception of:

1) An optional single segment memory buffer which can be read or
written as a whole by the hardware, may be provided.
2) An optional completion callback for all transmit operations, may
be provided.
3) Does not support mbufs.

For every i2c_adapter added by i2c_bit_add_bus we add a child to the
device named "lkpi_iicbb". This child handle the conversion between
Linux i2c_msgs to FreeBSD iic_msgs.
With the help of iic(4), this expose the i2c controller to userspace
allowing a user to query DDC information from a monitor.
e.g.: i2c -f /dev/iic0 -a 0x28 -c 128 -d r
will query the standard EDID from the monitor if plugged.

The bitbang part (lkpi_iicbb) isn't tested at all for now as I don't have
compatible hardware (all my hardware have native i2c controller).

Tested on: Intel (SandyBridge, Skylake, ApolloLake)
Tested on: AMD (Picasso, Polaris (amd64 and arm64))

LinuxKPI: import beginning of a new version of netdevice.h

Import a netdevice update complementing the last remaining bits of
the old ifnet derived implementation. Along add a (for now) task
based NAPI implementation.

This is the minimal set of chnages which are needed for the initial
support of wireless drivers. The NAPI implementation has an option to
still switch to "direct dispatch" as it had been used by these drivers
before not relying on a deferred context along with some printf tracing.
This has been helpful in the last weeks for debugging and will be
cleaned once we have had broader testing and are sure this is fine as-is.
Should we need a more time-sensitive or load-sensitive response
in the future we can always switch to something more sophisticated.

This is a work-in-progress implementation of sk_buff compat code
used for wireless drivers only currently.
Bring in this version of the code as it has proven to be good enough
to have packets going for a few months.

The current implementation has several drawbacks including the need
for us to copy data between sk_buffs and mbufs.
Do not rely on the internals of this implementation. They are highly
likely to change as we will improve the integration to FreeBSD mbufs.
