patches (created by me) add const qualifiers to the flexcan and
mpc5xxx_can driver. The next patch by Julia Lawall fixes a return value

Typically, the return value desired for the failure of a function with an
integer return value is a negative integer.  In these cases, the return
value is sometimes a negative integer and sometimes 0, due to a subsequent
initialization of the return variable within the loop.

A simplified version of the semantic match that finds this problem is:

netem does an early orphaning of skbs. Doing so breaks TCP Small Queue
or any mechanism relying on socket sk_wmem_alloc feedback.

Ideally, we should perform this orphaning after the rate module and
before the delay module, to mimic what happens on a real link :

skb orphaning is indeed normally done at TX completion, before the
transit on the link.

+-------+   +--------+  +---------------+  +-----------------+
+ Qdisc +---> Device +--> TX completion +--> links / hops    +->
+       +   +  xmit  +  + skb orphaning +  + propagation     +
+-------+   +--------+  +---------------+  +-----------------+
      < rate limiting >                  < delay, drops, reorders >

If netem is used without delay feature (drops, reorders, rate
limiting), then we should avoid early skb orphaning, to keep pressure
on sockets as long as packets are still in qdisc queue.

Ideally, netem should be refactored to implement delay module
as the last stage. Current algorithm merges the two phases
(rate limiting + delay) so its not correct.

skb_fill_rx_data() pulls 64 byte of data in skb->data

Its too much for TCP (with no options) on IPv4, as total size of headers
is 14 + 40 = 54

This means tcp stack and splice() are suboptimal, since tcp payload
is in part in tcp->data, and in part in skb frag.

The hash size is doubled when it needs to grow and compared against
hash_max. The >= comparison will limit the hash table size to half
of what is expected i.e. the default 512 hash_max will not allow
the hash table to grow larger than 256.

Also print the hash table limit instead of the desirable size when
the limit is reached.

Userspace implementations of network routing protocols sometimes need to
tell RA-originated IPv6 routes from other kernel routes to make proper
routing decisions. This makes most sense for RA routes with nexthops,
namely, default routes and Route Information routes.

The intended mean of preserving RA route origin in a netlink message is
through indicating RTPROT_RA as protocol code. Function rt6_fill_node()
tried to do that for default routes, but its test condition was taken
wrong. This change is modeled after the original mailing list posting
by Jeff Haran. It fixes the test condition for default route case and
sets the same behaviour for Route Information case (both types use
nexthops). Handling of the 3rd RA route type, Prefix Information, is
left unchanged, as it stands for interface connected routes (without
nexthops).

Lenght field should be encoded using big endian byte order, such as intend in the specs.
As it is currently written, the len field would not be decoded properly on an implementation using the correct byte ordering. Hence, it could lead to interroperability issues.
