instead of only OBJ_ANON objects that are backing, as it is now.
This is required for e.g. vm_meter is_object_active() detection, and
should be useful in some more cases.

Use refcount KPI for all objects, regardless of owning the object lock,
and the fact that currently OBJ_ANON cannot change for the live object.

TCP per RFC793 has 4 reserved flag bits for future use. One
of those bits may be used for Accurate ECN.
This patch is to include these bits in the LRO code to ease
the extensibility if/when these bits are used.

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.

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).
