ROSE network is organized through nodes connected via hamradio or Internet.
AX25 packet radio frames sent to a remote ROSE address destination are routed
through these nodes.
Without the present patch, automatic routing mechanism did not work optimally
due to an improper parameter checking.
rose_get_neigh() function is called either by rose_connect() or by
rose_route_frame().
In the case of a call from rose_connect(), f0 timer is checked to find if a connection
is already pending. In that case it returns the address of the neighbour, or returns a NULL otherwise.
When called by rose_route_frame() the purpose was to route a packet AX25 frame
through an adjacent node given a destination rose address.
However, in that case, t0 timer checked does not indicate if the adjacent node
is actually connected even if the timer is not null. Thus, for each frame sent, the
function often tried to start a new connexion even if the adjacent node was already connected.
The patch adds a "new" parameter that is true when the function is called by
rose route_frame().
This instructs rose_get_neigh() to check node parameter "restarted".
If restarted is true it means that the route to the destination address is opened via a neighbour
node already connected.
If "restarted" is false the function returns a NULL.
In that case the calling function will initiate a new connection as before.
This results in a fast routing of frames, from nodes to nodes, until
destination is reached, as originaly specified by ROSE protocole.

In nr_release(), one code path calls sock_orphan() which
will NULL out sk->sk_socket already.
In the other case, handling states other than NR_STATE_{0,1,2,3},
seems to not be possible other than due to bugs. Even for an
uninitialized nr->state value, that would be zero or NR_STATE_0.

The way that listening sockets work in ax25 is that the packet input
code path creates new socks via ax25_make_new() and attaches them
to the incoming SKB. This SKB gets queued up into the listening
socket's receive queue.
When accept()'d the sock gets hooked up to the real parent socket.
Alternatively, if the listening socket is closed and released, any
unborn socks stuff up in the receive queue get released.
So during this time period these sockets are unreachable in any
other way, so no wakeup events nor references to their ->sk_socket
and ->sk_sleep members can occur. And even if they do, all such
paths have to make NULL checks.
So do not deceptively initialize them in ax25_make_new() to the
values in the listening socket. Leave them at NULL.
Finally, use sock_graft() in ax25_accept().

There are many possible ways to add this "salt", thus I made this
patch to be the last in the series to change it if required.
Currently I propose to use the struct net pointer itself as this
salt, but since this pointer is most often cache-line aligned, shift
this right to eliminate the bits, that are most often zeroed.
After this, simply add this mix to prepared hashfn-s.
For CONFIG_NET_NS=n case this salt is 0 and no changes in hashfn
appear.

Selected device feature bits can be propagated to VLAN devices, so we
can make use of TX checksum offload and TSO on VLAN-tagged packets.
However, if the physical device does not do VLAN tag insertion or
generic checksum offload then the test for TX checksum offload in
dev_queue_xmit() will see a protocol of htons(ETH_P_8021Q) and yield
false.
This splits the checksum offload test into two functions:
- can_checksum_protocol() tests a given protocol against a feature bitmask
- dev_can_checksum() first tests the skb protocol against the device
features; if that fails and the protocol is htons(ETH_P_8021Q) then
it tests the encapsulated protocol against the effective device
features for VLANs
