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
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.

58a30d6a3c mlx4_core: 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.

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.

This patch removes random mac assignment on vf's. The vf's will start with
a zero mac and with upcoming support in fw/driver, a vf mac can be set
via the pf. vf's also support ndo_set_mac_address. This decision was made
based on the fact that a random mac on a vf is not really needed. And this
will reduce some of the problems with the vf's getting a new mac on
every driver load/unload (one of them being udev renaming the device on ever
load/unload and reboot).

10ef9ab432 be2net: event queue re-design
v2: Fixed up the bad typecasting pointed out by David...

In the current design 8 TXQs are serviced by 1 EQ, while each RSS queue
is serviced by a separate EQ. This is being changed as follows:

- Upto 8 EQs will be used (based on the availabilty of msix vectors).
Each EQ will handle 1 RSS and 1 TX ring. The default non-RSS RX queue and
MCC queue are handled by the last EQ.

- On cards which provide support, upto 8 RSS rings will be used, instead
of the current limit of 4.

The new design allows spreading the TX multi-queue completion processing
across multiple CPUs unlike the previous design.
