mlx5: Add raw ethernet local loopback support.

Currently, unicast/multicast loopback raw ethernet (non-RDMA) packets
are sent back to the vport. A unicast loopback packet is the packet
with destination MAC address the same as the source MAC address. For
multicast, the destination MAC address is in the vport's multicast
filter list.

Moreover, the local loopback is not needed if there is one or none
user space context.

After this patch, the raw ethernet unicast and multicast local
loopback are disabled by default. When there is more than one user
space context, the local loopback is enabled.

Note that when local loopback is disabled, raw ethernet packets are
not looped back to the vport and are forwarded to the next routing
level (eswitch, or multihost switch, or out to the wire depending on
the configuration).

r357614 added CTLFLAG_NEEDGIANT to make it easier to find nodes that are
still not MPSAFE (or already are but aren’t properly marked).
Use it in preparation for a general review of all nodes.

This is non-functional change that adds annotations to SYSCTL_NODE and
SYSCTL_PROC nodes using one of the soon-to-be-required flags.

Mark all obvious cases as MPSAFE. All entries that haven't been marked
as MPSAFE before are by default marked as NEEDGIANT

Implement hardware TLS via send tags for mlx5en(4), which is supported by
ConnectX-6 DX.

Currently TLS v1.2 and v1.3 with AES 128/256 crypto over TCP/IP (v4
and v6) is supported.

A per PCI device UMA zone is used to manage the memory of the send
tags. To optimize performance some crypto contexts may be cached by
the UMA zone, until the UMA zone finishes the memory of the given send
tag.

An asynchronous task is used manage setup of the send tags towards the
firmware. Most importantly setting the AES 128/256 bit pre-shared keys
for the crypto context.

Updating the state of the AES crypto engine and encrypting data, is
all done in the fast path. Each send tag tracks the TCP sequence
number in order to detect non-contiguous blocks of data, which may
require a dump of prior unencrypted data, to restore the crypto state
prior to wire transmission.

Statistics counters have been added to count the amount of TLS data
transmitted in total, and the amount of TLS data which has been dumped
prior to transmission. When non-contiguous TCP sequence numbers are
detected, the software needs to dump the beginning of the current TLS
record up until the point of retransmission. All TLS counters utilize
the counter(9) API.

In order to enable hardware TLS offload the following sysctls must be set:
kern.ipc.mb_use_ext_pgs=1
kern.ipc.tls.ifnet.permitted=1
kern.ipc.tls.enable=1
