4dd5867a79 net: conn: Fix is_invalid_packet
In switch statement break statement was missing causing IPv4 part to
execute even if the packet is IPv6. Also logical negation is wrong in
this context.

38866179a5 net: icmpv6: Fix error condition
When calling net_frag_read(), frag == NULL is an error only if pos is
not zero. It is thus incorrect to throw an error only if !frag, as
pos must also be checked to be not zero.

89f57c225a net: tcp: Define single config option for TIME_WAIT delay
Previously, there was a boolean CONFIG_NET_TCP_TIME_WAIT setting
("master switch") and numeric CONFIG_NET_TCP_2MSL_TIME setting,
both named not ideally (there were both NET_TCP_TIME_WAIT and
CONFIG_NET_TCP_TIME_WAIT symbols in the source, with very different
meaning; "2MSL_TIME" was also a roundabout way to refer to
TIME_WAIT state time). In addition to that, some code was defining
adhoc, hardcoded duplicates for these settings.

CONFIG_NET_TCP_2MSL_TIME was also measured in seconds, giving
poor precision control for this resource-tying setting.

Instead, replace them all with the single
CONFIG_NET_TCP_TIME_WAIT_DELAY setting, measured in milliseconds.
The value of 0 means that TIME_WAIT state is skipped.

Fixes: #7459

trying to call print_send_info() on it leads to errors:

[net/pkt] [ERR] net_pkt_tcp_data: NULL fragment data!

This change is similar to how print_send_info() is called in

According to RFC 793 we should wait for FIN in FIN_WAIT_1 and
FIN_WAIT_2 states. Receiving ACK in FIN_WAIT_1 just moves us to
FIN_WAIT_2 state.

Right now TCP connection is never closed if FIN is not received
in FIN_WAIT_2 state. Fix that by keeping fin_timer active in
FIN_WAIT_2 state, but canceling it just after FIN is received.
