c4a692a85f net: ppp: Add proper support to receive Echo-Reply message
Currently only net-shell calls net_ppp_ping() command, so make
it return the amount of time that it took to receive Echo-Reply
so the net-shell can print the round trip time value.

144dc592a6 net: ip: 6lo: Remove unnecessary net_buf allocation and memmove
This patch tries to avoid memmoves and buffer allocations when there
is enough space in the original buffer. Headers are still contiguous

f10da7b643 net: ip: 6lo (IPHC) uncompression rework
This is a rework of the 6lo IPHC uncompression.
The uncompression now tries to work in place on the original buffer
instead of allocation a new one. If there is not enough tail-room,
a new buffer is allocated and filled with the IP and maybe UDP header.
The compressed header is pulled from the original buffer and the
buffer is preserved.

0261ecdee4 net: ip: net_pkt: Add pkt_cursor_advance before contiguous check
When net_pkt_skip skips the entire data in a net buffer, the cursor
still points to this buffer on data that is off by one.
Calling pkt_cursor_advance in net_pkt_is_contiguous fixes this and
moves the cursor to the next buffer.

eccc268d0a net/iface: Rework how routers are handled
- router lifetime is always a u16_t so fixing
net_if_ipv6_router_update_lifetime() signature.
- Coalescing router timers into one: this reduces the net_if_router
structure by 22 bytes
- refactor IPv6 and IPv4 router code so it's handled in generic
functions, to avoid duplicating 90% of the code for each family. This
also fixes the lifetime support for IPv4 which was missing.

Note however that IPv4 routing support seems to be missing as none of
the relevant functions are used anywhere yet.

This reduces the size of struct net_if_ipv6 by 24 bytes by moving
the k_delayed_work attribute into net_if core code.
Then each net_if_ipv6 can be added to the timer handler via a slist.

This does not make much gain if the system has only 1 network interface
It starts to be interesting if it has 2+ network interfaces then.

This reduces the size of struct net_if_addr by 24 bytes by moving
the k_delayed_work attribute into net_if core code.
Then each net_if_addr can be added to the timer handler via a slist.

This does not make much gain if the system has only 1 unicast IPv6
address. It's a nice memory improvment once it has 2+ unicast IPv6
address. Note that having IPv4 enabled along with IPv6 will also see
memory improvements since both IPv6 and IPv4 use the same struct
net_if_addr.
