The af_xdp plugin does not support chained buffers; attempting to send
chain buffers will result truncated packets or even send other packet's
data. As a workaround, turn any buffer chain into a single buffer before
tx.

This patch introduces sw_ring. This ring is used in next set of patchas
and plays role of a buffer for QAT, allowing collecting frame elements
in case QAT queue is fully utilized, and assembling frame
from QAT dequeued elements.

The async frames pool may be resized once drained. This will cause 2 problems: original pool pointer is invalidated and pool size changed, both problems will confuse the crypto infra user graph nodes (like IPsec and Wireguard) and crypto engines if they expect the pool pointers always valid and the pool size never changed (for performance reason).
This patch introduces fixed size of the async frames pool. This helps zeroing surprise to the components shown above and avoiding segmentation fault when pool resizing happened. In addition, the crypto engine may take advantage of the feature to sync its own pool/vector with crypto infra.

Linux uses NLM_F_REPLACE in the netlink message to signal a FIB update
The code invariably does a FIB update for IPv4 and a addition for IPv6.
Without this fix, the following:
ip route add 2001:db8::/48 via 2001:db8::1
ip route replace 2001:db8::/48 via 2001:db8::2
ends up as two separate FIB entries in VPP. With the fix, there will be one FIB entry (the second one with nexthop ::2).

to an external application i.e. VPP.
Usage:
1) Start VPP with following config.

create interface memif id 1 master
set int state memif0/0 up
set int state memif0/1 up
create packet-generator interface pg0
set int state pg0 up
create packet-generator interface pg1
set int state pg1 up
set int l2 xconn pg0 memif0/0
set int l2 xconn memif0/0 pg0

The plugin creates and manages adjacencies for the physical interface in
each interface pair (they are part of the x-connect feature). When a
link update notification is received from the host system, MAC address
of the corresponding physical interface is updated (as needed) as well
as previously created adjacencies for it (because a new rewrite string
needs to be generated).
Subinterfaces inherit MAC address from the parent interface. When MAC
address of the parent interface changes, it also implies MAC address
change for its subinterfaces. The problem is that this is currently not
considered in the plugin. After MAC address update on the parent
interface, packets sent from subinterfaces might have wrong source MAC
address. For example, IPv6 Neighbor Solicitation messages will be sent
with the wrong (previous) MAC address and neighbor discovery will fail.
With this fix, when the plugin updates adjacencies for a physical
interface, it will also update adjacencies for the subinterfaces with
existing interface pair.

When dumping packets from multiple threads using the API, first all
packets from thread 0 are dumped then all ones from thread 1, etc
Until we reach the limit specified by the API call, so we could never
get packets trace from threads with higher ids.
However, the tracedump CLI dump a maximum number of packets from all
threads, which we can expect from the API to do.
We also add a trace_clear_cache API so the client gets an answer when
he only wants to clear its packet cache.
