2012-02-15net: use eth_hw_addr_random() and reset addr_assign_typeDanny Kukawka
Use eth_hw_addr_random() instead of calling random_ether_addr() to set addr_assign_type correctly to NET_ADDR_RANDOM. Reset the state to NET_ADDR_PERM as soon as the MAC get changed via .ndo_set_mac_address. v2: adapt to renamed eth_hw_addr_random() Signed-off-by: Danny Kukawka <danny.kukawka@bisect.de> Signed-off-by: David S.

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.

2012-02-14tg3: Remove unneeded link_config.orig_... membersMatt Carlson
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.

2012-02-14tg3: Remove unused link config codeMatt Carlson
When tg3 devices are shutdown, the driver uses the TG3_PHYFLG_IS_LOW_POWER flag to enable a static phy configuration. Any attempt to use the link configuration variables is dead code.

2012-02-14tg3: Reduce UMP event collision windowMatt Carlson
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.

2012-02-13e1000e: cleanup goto statements to exit points without common workBruce Allan
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.
