e53fccd36c Add route for session-specific subprefix of the ipv6 prefix 
Otherwise with kernel acceleration we would only have the same /64 route
on all ppp devices. We need separate /96 routes on each ppp device for
packets of the /96 subprefix to be routed to the correct session.

b2bc6da827 Add support for deleting all kernel tunnels/sessions 
Unfortunately, tunnels and session can survive us, so we have to drop any
tunnel/session left from a previous instance that might have crashed.

e442a69fc1 cluster: try make the cluster socket high-priority 
The heartbeat messages, notably, should really not be lost, otherwise the
cluster will dismantle itself if some very-high trafic is filling packet
queues.

9daccab8ba shutdown_handler: really shutdown when we are last 
If we are a master and we don't have peers, there is no use keeping the
sessions alive, when we'll restart we will have forgotten them all.
Better gracefully close them, so they can be quickly respawn on restart,
instead of having to wait for timeouts.

05772e2295 Add periodic RA sends 
The RFC indeed say that we should send them periodically.  We were
previously only sending them along LCP echo replies, but echo requests
are typically sent only when there is no trafic, which RA need to be
sent even when there is trafic.

3667bdfe80 Also clamp MSS on IPv6 
Some routers erratically drop "Packet too big" icmp messages, and PMTU
discovery then doesn't work. We can however easily clamp MSS on IPv6 too.

zeroed in initdata so we can just remove it.

e168cc6ff7 icmp.c: do not include linux headers 
net/if.h and linux/if.h headers conflict with each other as of linux
6.3 and glibc 2.37 headers:
In file included from /usr/include/linux/icmp.h:23,
                 from icmp.c:5:
/usr/include/net/if.h:44:5: error: redeclaration of enumerator ‘IFF_UP’
   44 |     IFF_UP = 0x1,               /* Interface is up.  */
      |     ^~~~~~
/usr/include/linux/if.h:83:9: note: previous definition of ‘IFF_UP’ with type ‘enum net_device_flags’
   83 |         IFF_UP                          = 1<<0,  /* sysfs */
      |         ^~~~~~

icmp.c gets net/if.h from l2tpns.h, and linux/if.h from linux/icmp.h.

In our case, we do not need to use the linux headers at all here as we
are doing normal userspace things: just use glibc headers all the way.

This has been tested with kernel 3.2 / glibc 2.13 headers, so it's
probably fine. (l2tpns does not currently build with musl)
