fix byte order error about the struct snat_address_t's member net.
for example configurations:
set interface ip table loop1 1
set interface ip addr loop1 10.10.10.2/24
nat44 add address 10.10.10.2 tenant-vrf 1
the snat address's net should be "as_u8 = {0xa, 0xa, 0xa, 0x0}",
but now it's "as_u8 = {0x0, 0xa, 0xa, 0x2}" because of missing
transition of byte order about the member net of snat_address_t.
(gdb) p/x *snat_main->addresses
$3 = {addr = {data = {0xa, 0xa, 0xa, 0x2}, data_u32 = 0x20a0a0a,
as_u8 = {0xa, 0xa, 0xa, 0x2}, as_u16 = {0xa0a, 0x20a},
as_u32 = 0x20a0a0a}, net = {data = {0x0, 0xa, 0xa, 0x2},
data_u32 = 0x20a0a00, as_u8 = {0x0, 0xa, 0xa, 0x2},
as_u16 = {0xa00, 0x20a}, as_u32 = 0x20a0a00},

1) Removed deprecated API.
- These specific APIs do not have repleacement
because features that they controled
aren't part of current NAT44-ED
implementation anymore.
2) Removed unused typedef of port allocation funciton.
- Missed left over removed.

Putting a breakpoint in gdb, I found out ctx was free in mbedtls_app_close.
Looking at app_close function in picotls and openssl, I don't see they
free ctx and they don't crash when processing cleanup. I am inclined to
think that mbedtls_ctx_free should not be called in mbedtls_app_close

CQE flags located in bits 16-31 at offset 0x1c should be defined as
actual numbers instead of indexes. Besides, L3 header type for IPv4 is
10(2 in decimal) and for IPv6 is 01(1 in decimal) according to CQE entry
fields description of page 120 in Mellanox Programmer Reference Manual.
(https://network.nvidia.com/files/doc-2020/ethernet-adapters-programming-manual.pdf)
Fixing this issue will lead to correct CQE flags printing for rdma-input

are IPv4 packets with flag l3_ok set
- mask/match variables should be converted to network byte order to

Type: fix
Currently, when a wg interface is administratively disabled initially or
during operation, handshake packets continue to be sent. Data packets
stop being sent because routes pointing to the wg interface will not be
used. But data keys remain.
With this fix, when a wg interface is administratively disabled during
peer creation, avoid connection initialization to the peer. Data keys
and timers should be empty at this point. When a wg interface is
disabled during operation, disable all peers (i.e. stop all timers,
clear data keys, etc.). Thus, state should be identical in both cases.
When a wg interface is administratively enabled, enable all peers (i.e.
get ready to exchange data packets and initiate a connection). Also,
cover these scenarios with tests.

Internaly, vpp uses it's own padding, so all the data
is padded using blocksize in /src/vnet/ipsec/ipsec.c
Openssl should add it's own padding, but the data
is already padded. So on decrypt stage when padding
should be removed, it can't be done. And it produces
error `bad decrypt`
Previous versions of openSSL decrypted data almost
at the beginning of EVP_DecryptUpdate/EVP_DecryptFinal_ex
and produced the same error, but data was already decrypted.
Now it's not, so some algorithms could have some problems
with it
PS. openSSL 3.x.x

Type: fix
As per the protocol:
A handshake initiation is retried after "REKEY_TIMEOUT + jitter" ms,
if a response has not been received...
Currently, if retransmit handshake timer is started, it will trigger
after "REKEY_TIMEOUT + jitter" ms and will try to send a handshake
initiation via wg_send_handshake() given that no responses have been
received. wg_send_handshake() will verify that time stored in
REKEY_TIMEOUT has passed since last handshake initiation sending and if
has, will send a handshake initiation. Time when a handshake initiation
was last sent is stored in last_sent_handshake.
The problem is that last_sent_handshake is not only updated in
wg_send_handshake() when sending handshake initiations but also in
wg_send_handshake_response() when sending handshake responses. When
retransmit handshake timer triggers and a handshake response has been
sent recently, a handshake initiation will not be sent because for
wg_send_handshake() it will look like that time stored in REKEY_TIMEOUT
has not passed yet. Also, the timer will not be restarted.
wg_send_handshake_response() must not update last_sent_handshake,
because this time is used only when sending handshake intitiations. And
the protocol does not say that handshake initiation retransmission and
handshake response sending (i.e. replying to authenticated handshake
initiations) must coordinate.
With this fix, stop updating last_sent_handshake in
wg_send_handshake_response().
Also, this fixes tests that used to wait for "REKEY_TIMEOUT + 1" seconds
and did not receive any handshake initiations. Then they fail.
Also, long-running tests that send wrong packets and do not expect
anything in reply may now receive handshake intiations, consider them as
replies to the wrond packets, and fail. Those are updated to filter out
handshake initiations in such verifications. Moreover, after sending
wrong packets, error counters are already inspected there to confirm
packet processing was unsuccessful.

The number of available dynamic ports is set to (0xffff - 1024) =
64511, which is not divisable by the pow2 number of workers - the
only integer divisors are 31 and 2081.
So, total dynamic port range of all workers will be less than it:
1 wrk: n = (port_per_thread = 64511/1)*1 = 64511 + 1025 = 65536
2 wrk: n = (port_per_thread = 64511/2)*2 = 64510 + 1025 = 65535
4 wrk: n = (port_per_thread = 64511/4)*4 = 64508 + 1025 = 65533
8 wrk: n = (port_per_thread = 64511/8)*8 = 64504 + 1025 = 65529
...
As seen, with multiple workers there are unused trailing ports for every
nat pool address and that is the reason of out-of-bound index in the
worker array on out2in path due (port - 1024) / port_per_thread math.
This was fixed in 5c9f9968de63fa627b4a72b344df36cdc686d18a, so packets
to unused ports will go to existing worker and dropped there.
Per RFC 6335 https://www.rfc-editor.org/rfc/rfc6335#section-6:
6. Port Number Ranges
o the System Ports, also known as the Well Known Ports, from 0-1023
(assigned by IANA)
o the User Ports, also known as the Registered Ports, from 1024-
49151 (assigned by IANA)
o the Dynamic Ports, also known as the Private or Ephemeral Ports,
from 49152-65535 (never assigned)
According that let's allocate dynamic ports from 1024 and have full port
range with a wide range of the workers number - 64 integer divisors in
total, including pow2 ones:
1 wrk: n = (port_per_thread = 64512/1)*1 = 64512 + 1024 = 65536
2 wrk: n = (port_per_thread = 64512/2)*2 = 64512 + 1024 = 65536
3 wrk: n = (port_per_thread = 64512/3)*3 = 64512 + 1024 = 65536
4 wrk: n = (port_per_thread = 64512/4)*4 = 64512 + 1024 = 65536
5 wrk: n = (port_per_thread = 64512/5)*5 = 64510 + 1024 = 65534
6 wrk: n = (port_per_thread = 64512/6)*6 = 64512 + 1024 = 65536
7 wrk: n = (port_per_thread = 64512/7)*7 = 64512 + 1024 = 65536
8 wrk: n = (port_per_thread = 64512/8)*8 = 64512 + 1024 = 65536
...
Modulo from 5c9f9968de63fa627b4a72b344df36cdc686d18a is still required
when the numbers of workers is not the integer divisor of 64512.

was being called to update a peer's address if necessary after
processing a received packet. Check in the worker whether this is
necessary before incurring the overhead of the RPC to the main thread.

Originally initialization cryptodev device(s) calls double request
to enabled async mode and increased ref count twice for async mode.
Due to this cannot be change any assigned async handlers to other
async crypto engine.
The fixes reduce double request to enable async mode in initialization
cryptodev device(s) and VPP can be change assigned async handlers
to other crypto engine after disabled all async feature, for example:
ipsec, wireguard.

The unformat type for "%d" should be u32 or int, otherwise the 'did' in
high stack address will be overflow to zero by the 'qid' which is in the
low stack address.
Like input "dev wq3.2" will return "did=0, qid=2".

When there is a bad descriptor, it may in the beginning, in the middle,
or at the end of the batch if the batch has more than 3 descriptors.
When processing a bad descriptor is encountered in the batch, we need to
rollback n_buffers in memif_process_desc(), or the statement in the same
function
memif_add_copy_op (ptd, mb0 + src_off, bytes_to_copy,
dst_off, n_buffers - 1);
is wrong because it picks up the wrong buffer_vec_index of the bad
descriptor while parsing a good descriptor immediately following the
bad descriptor. n_buffers was incremented in the beginning of
while (n_left) loop.
The other problem is we should count the number of bad packets and
reduce ptd->n_packets to get the correct number of packets for subsequent
processing in device_input.
The last fix is to check if n_buffers == 0 in device_input and skip
doing any descriptor copy. This case can happen when all the descriptors
are bad in the batch.
