Currently bnx2x statistics are reset by inner driver reload, e.g. by MTU
change. This patch fixes this issue - from now on statistics should only
be reset upon device closure.
Thanks to Michal Schmidt <mschmidt@redhat.com> for his initial patch
regarding this issue.

Add unicast steering entries to resource tracker.
Do qp_detach also for these entries when VF doesn't shut down gracefully.
Otherwise there is leakage of these resources, since they are not tracked.

When adding new unicast steer entry, before moving qp to state ready,
actually before calling mlx4_RST2INIT_QP_wrapper(), there were added
a lot of entries with local_qpn=0 into radix tree.
This fact impacted the get_res() function and proper functioning
of resource tracker in addition to adding trash entries into radix tree.

This patch removes the unneeded link_config.orig_* members.  When the
phy is in a low power state, the TG3_PHYFLG_IS_LOW_POWER flag solely
determines how the link is configured.  When the phy is powered back up,
it can resume using the original settings.

For the phylib case, the link configuration still needs to be saved, but
since the phylib maintains its own configuration, we can repurpose the
(unused in this case) tg3 link configuration members.

The tg3 driver needs to submit a few phy register values to the UMP
firmware each time the link state changes.  Up until now, the driver
would wait for the previous event to complete, then proceed to gather
data through a series of phy accesses.  Since phy accesses are
relatively slow, it is possible for another thread to attempt to submit
its own event while the UMP code is still construction its message.

This patch seeks to minimize the collision window as much as possible by
preloading the phy data.

Per ./Documentation/CodingStyle, goto statements are acceptable for the
centralized exiting of functions when there are multiple exit points which
share common work such as cleanup.  When no common work is required for
multiple exit points, the function should just return at these exit points
instead of doing an unnecessary jump to a centralized return.  This patch
cleans up the inappropriate use of goto statements, and removes unnecessary
variables (or move to a smaller scope) where possible as a result of the
cleanups.
