USB-200 and USB-250 dongles and sets a flag to send HCI_Reset as
the first command.

As BHs are off in loopback_xmit(), preemption cannot occurs, so we can
use __get_cpu_var() instead of per_cpu() (and avoid a
preempt_enable()/preempt_disable() pair)

Lot of routers/embedded devices still use CPUS with 16/32 bytes cache
lines.  (486, Pentium, ...  PIII) It makes sense to group together
fields used at lookup time so they fit in one cache line.  This reduce
cache footprint and speedup lookups.

The 32bit compatibility layer has no CAP_NET_ADMIN check in
compat_do_ipt_get_ctl, which for example allows to list the current
iptables rules even without having that capability (the non-compat
version requires it). Other capabilities might be required to exploit
the bug (eg. CAP_NET_RAW to get the nfnetlink socket?), so a plain user
can't exploit it, but a setup actually using the posix capability system
might very well hit such a constellation of granted capabilities.

Fixes the implementation of the ethtool set ring parameters for the
tg3 transmit ring.  The size of tx_pending is taken into account
before doing a netif_wake_queue.  This prevents the interface from
locking up when smaller transmit ring sizes are used.

We dont need a full struct net_device_stats (currently 23 long : 184 bytes on

We save few CPU cycles too in loopback_xmit() not updating 4 fields, but 2.

This patch fixes a silly bug that has been in the input routing code
for some time. It results in trying to send to a node directly when
the origin of the packet is via the default router.

reported the bug and its a fairly obvious fix for a typo.

This patch limits the amount of time you will defer sending a TSO segment
to less than two clock ticks, or the time between two acks, whichever is
longer.

On slow links, deferring causes significant bursts.  See attached plots,
which show RTT through a 1 Mbps link with a 100 ms RTT and ~100 ms queue
for (a) non-TSO, (b) currnet TSO, and (c) patched TSO.  This burstiness
causes significant jitter, tends to overflow queues early (bad for short
queues), and makes delay-based congestion control more difficult.

Deferring by a couple clock ticks I believe will have a relatively small
impact on performance.

This patch corrects an issue wherein a previouly failed node could
not reestablish a links to a non-failing node in the TIPC network
until the latter node detected the link failure itself (which might
be configured to take up to 30 seconds).  The non-failing node now
responds to link setup requests from a previously failed node in at
most 1 second, allowing it to detect the link failure more quickly.

2) Now uses TIPC_NULL print buffer structure to indicate null device

3) Fixed misuse of console buffer structure by tipc_dump()
4) Added and corrected comments in various places
