75c6062cb7 mlx4: fix buffer overrun
When passing MLX4_UC_STEER=1 it was translated to value 2
after mlx4_QP_ATTACH_wrapper. Therefore in new_steering_entry()
unicast steer entries were added to index 2 of array of size 2.
Fixing this bug by shift right to one position.

3013dc0cce 3c59x: shorten timer period for slave devices
Jean Delvare reported bonding on top of 3c59x adapters was not detecting
network cable removal fast enough.

3c59x indeed uses a 60 seconds timer to check link status if carrier is
on, and 5 seconds if carrier is off.

This patch reduces timer period to 5 seconds if device is a bonding
slave.

eb40d89276 mlx4: add unicast steering entries to resource_tracker
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.

0ee9f1dd7b mlx4: fix QP tree trashing
When adding new unicast steer entry, before moving qp to state ready,
actually before calling mlx4_RST2INIT_QP_wrapper(), there were added

This fact impacted the get_res() function and proper functioning
of resource tracker in addition to adding trash entries into radix tree.

c6700ce224 tg3: Remove unneeded link_config.orig_... members
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.

b28f389d92 tg3: Reduce UMP event collision window
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.

5015e53a4c e1000e: cleanup goto statements to exit points without common work
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.
