The general idea is that if we learn new PMTU information, we
bump the peer genid.
This triggers the dst_ops->check() code to validate and if
necessary propagate the new PMTU value into the metrics.
Learned PMTU information self-expires.
This means that it is not necessary to kill a cached route
entry just because the PMTU information is too old.
As a consequence:
1) When the path appears unreachable (dst_ops->link_failure
or dst_ops->negative_advice) we unwind the PMTU state if
it is out of date, instead of killing the cached route.
A redirected route will still be invalidated in these
situations.
2) rt_check_expire(), rt_worker_func(), et al. are no longer
necessary at all.

With previous patch, rose_get_neigh() routine
investigates the full list of neighbor nodes
until it finds or not an already connected node whether
it is called locally or through a level 3 transit frame.
If no routes are opened through an adjacent connected node
then a classical connect request is attempted.
Then there is no more reason for an extra loop such
as the one removed by this patch.

FPAC AX25 packet application is using Linux kernel ROSE
routing skills in order to connect or send packets to remote stations
knowing their ROSE address via a network of interconnected nodes.
Each FPAC node has a ROSE routing table that Linux ROSE module is
looking at each time a ROSE frame is relayed by the node or when
a connect request to a neighbor node is received.
A previous patch improved the system time response by looking at
already established routes each time the system was looking for a
route to relay a frame. If a neighbor node routing the destination
address was already connected, then the frame would be sent
through him. If not, a connection request would be issued.
The present patch extends the same routing capability to a connect
request asked by a user locally connected into an FPAC node.
Without this patch, a connect request was not well handled unless it
was directed to an immediate connected neighbor of the local node.
Implemented at a number of ROSE FPAC node stations, the present patch
improved dramatically FPAC ROSE routing time response and efficiency.

Bosch C_CAN controller is a full-CAN implementation which is compliant
to CAN protocol version 2.0 part A and B. Bosch C_CAN user manual can be
obtained from:
http://www.semiconductors.bosch.de/media/en/pdf/ipmodules_1/c_can/users_manual_c_can.pdf
This patch adds the support for this controller.
The following are the design choices made while writing the controller
driver:
1. Interface Register set IF1 has be used only in the current design.
2. Out of the 32 Message objects available, 16 are kept aside for RX
purposes and the rest for TX purposes.
3. NAPI implementation is such that both the TX and RX paths function
in polling mode.
