When the network interface goes down, we call
net_ipv4_autoconf_reset() which removes the autoaddress
from the network interface.
The net_ipv4_autoconf_reset() is also called when ACD is started
in which case we could see this error message
<dbg> net_if_start_acd: Starting ACD for iface 2
<err> net_if: iface 2 addr 169.254.174.230 (net_if_ipv4_addr_rm():4625)
<dbg> net_if_ipv4_addr_rm: Address 169.254.174.230 not found (-22)
This error is superfluous and not needed. So before trying to
remove the address, check if the interface already has it set and
only then remove it.

When adding IPv4 address to the network interface, there is no
need to start ACD procedure for localhost or point-to-point links.
The ACD start function would mark the IP address like 127.0.0.1 as
tentative and never make it preferred which would then cause issues
when selecting the network address for sending.
As the ACD start is also called when the network interface comes up,
add the localhost and point-to-point link check to ACD start function
so that we will avoid ACD checks in this case.

Add this to set link speed through net_shell.
Current zephyr version doesn't have user interface to change
speed, hence adding this to accomodate it. Full duplex will
be set by default for each link speed.
Able to change link speed using command below:
net iface set_link <iface idx> <speed> <optional:h(half)/f(full)>
eg: net iface set_link 1 100 h
net iface set_link 1 10 f
net iface set_link 1 1000
Able to set multiple link speed like below:

The send_queue was used as SYN/FIN packet retransmission. Before
the SYN/FIN being ACKed and dequeue-ed, the following packets in
the send_queue cannot be sent out. That's why Zephyr had to send
a FIN+ACK instead of a duplicated ACK-only in FINWAIT1, CLOSING.
In fact, we can take SYN/FIN as kind of data and use the same
send_data_timer for retransmission, like other OSes do. This way,
the send_queue is simply used for local traffics.
Benefits (in theory):
1. The code is easier,
2. TxPkt performance is better after skipping enq/deq send_queue,
3. The struct tcp{} node is a few bytes smaller, saving memory.

TCP implementation provided the parent net_context pointer to the

sockets explicitly registered parent context as user_data, however it

Based on TCP Spec., the outgoing TCP packets shoud use SND.NXT as
the seqnum. In Zephyr, the conn->seq works as the SND.UNA and the
conn->seq + conn->unacked_len works as the SND.NXT. Currently, it
uses SND.UNA in tcp_out() as the seqnum, which might get dropped
as old packets and could not deliver the message to the peer.
A few exceptions use SND.NXT - 1 as the seqnum are: keepalive,
zero-window-probe, FIN/SYN retransmissions. And, for closing a
connection, Zephyr won't send out FIN until all the data has been
ACKed, so the conn->unacked_len is 0 and it is ok to use conn->seq
as the SND.NXT.

This prevents from using "udp send" after "udp bind", which

otherwise.

And, all the RST packet should use net_tcp_reply_rst() instead of

Connection manager enforces non-blocking disconnect() behavior, yet in
case CONN_MGR_IF_NO_AUTO_DOWN flag is not set, it'd put the interface
down right after, disrupting the disconnect process.
As putting the interface down can be handled in the corresponding event
handler as well, when the interface is actually disconnected, remove the
conn_mgr_conn_if_auto_admin_down() call from conn_mgr_if_disconnect().
To make this work with persistence flag, introduce a new internal flag
indicating that the interface is in active disconnect.
Finally, since it isn't really necessary that disconnect() API call is
non-blocking, remove that requirement.

The NULL-pkt parameter for tcp_in() was designed for generating

To simplify the tcp_in() code logic and make it better under-

and tp_input() to use. Thus, the tcp_in() only handles the in-
coming TCP packets.
