rose: improving AX25 routing frames via ROSE network
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.

ax25: Use sock_graft() and remove bogus sk_socket and sk_sleep init.
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().

mac80211: eliminate IBSS warning in rate_lowest_index()
In IBSS mode prior to join/creation of new IBSS it is possible that
a frame from unknown station is received and an ibss_add_sta() is
called. This will cause a warning in rate_lowest_index() since the
list of supported rates of our station is not initialized yet.
The fix is to add ibss stations with a rate we received that frame
at; this single-element set will be extended later based on beacon
data. Also there is no need to store stations from a foreign IBSS.

mac80211: add helpers for frame control testing
A few general categories:
1) ieee80211_has_* tests if particular fctl bits are set, the helpers are de
in the same order as the fctl defines:
A combined _has_a4 was also added to test when both FROMDS and TODS are set.
2) ieee80211_is_* is meant to test whether the frame control is of a certain
ftype - data, mgmt, ctl, and two special helpers _is_data_qos, _is_data_pres
which also test a subset of the stype space.
When testing for a particular stype applicable only to one ftype, functions
like ieee80211_is_ack have been added. Note that the ftype is also being
checked in these helpers. They have been added for all mgmt and ctl stypes
in the same order as the STYPE defines.
3) ieee80211_get_* is meant to take a struct ieee80211_hdr * and returns a
pointer to somewhere in the struct, see get_SA, get_DA, get_qos_ctl.
The intel wireless drivers had helpers that used this namespace, convert the
all to use the new helpers and remove the byteshifting as they were defined
in cpu-order rather than little-endian.
