We don't need to print log messages when we encounter an out-of-memory

message that duplicates the one emitted by the netdev layer, and a

As reported by Eric Dumazet, the driver is not masking the right
bits in the receive descriptor before it starts checking them.

This patch extends the mask to allow for the right bits to be
checked, and fixes the issue permanently via a define.

Intel Wired LAN Driver Updates 2014-06-06

This series contains updates to i40e and i40evf.

Shannon sets the lan_veb index when the Virtual Ethernet Bridge (VEB) is
created for the basic LAN device and its Virtual Switch Interfaces (VSIs).
Also adds the VEB/VSI statistics in the ethtool stats output.  Increases the
reset wait time because the original time was too optimistic and resets
were failing after EMPR.  This won't delay the actual wait, just allows
us to poll more times as needed.  He fixes the attempted removal of the
HMC space and unhook IRQs when a reset recovery fails because the HMC space
never got setup and IRQs are already unhooked in the first place, so the
removal is not necessary.

Jesse adds a log message for pre-production hardware so that the user is
notified that there may be issues with the hardware, yet does not prevent
the user from using the hardware.  Add the printing of link messages
in the i40e driver like all the other Intel Ethernet drivers.

Mitch makes log message changes to i40evf to prevent confusion by making
the most common messages less scary by lowering them to a less terrifying
log level.  This is due to the fact that depending on the timing of what
the PF driver is doing, it may take a few tries before the VF driver is able
to communicate with the PF driver on init or reset recovery.

Kamil provides a change to prevent the driver from getting into a endless
loop while trying to send GetVersion AQ command, since BO silicon blocks
AQ registers when in Blank Flash mode.  So introduce a simple check for a
correct value in one of the AQ registers to be sure that AQ was configured
correctly.

Matt adds a function which indicates our intention to enable or disable a
particular transmit queue.  Also adds a function to notify the device's
transmit unit that we are about to enable or disable a transmit queue.

Use an extra state variable to keep track of when the IRQs are fully

left unhooked in a failed reset recovery, e.g. when firmware is broken.

If a reset recovery failed (e.g. firmware is broken), the HMC space won't
get set up.  We don't need to try to delete it if it didn't get set up.
This stops some needless error messages when we already know we need to
just tear things down.

2) Fix broken ordering when adding set element transactions.
