This change moves work_limit, total_packets, and total_bytes into the ring
container struct of the q_vector. The advantage of this is that it should
reduce the size of memory used in the event of multiple rings being
assigned to a single q_vector. In addition it should help to reduce the
total workload for calculating itr since now total_packets and total_bytes
will be the total work done of the interrupt instead of for the ring.

This patch adds support for a ring container structure to be used within
the q_vector. The basic idea is to provide a means of separating the RX
and TX rings while maintaining a common structure for their containment.
The advantage to this is that later we should be able to pass this
structure to the update_itr functions without needing to pass individual
rings.

The ixgbe_maybe_stop_tx function is only a few lines long and is called
multiple times through the xmit hotpath. In order to streamline things it
makes sense to just inline it.

This change is meant to update ATR so that it will use the recorded RX
queue instead of the CPU in the case of routing. This change is meant to
help ixgbe default behavior to more closely match that of the kernel.

Prior to this change, most PHY configuration parameters were passed
into the STMMAC device as a separate PHY device. As well as being
unusual, this made it difficult to make changes to the MAC/PHY
relationship.
This patch moves all the PHY parameters into the MAC configuration
structure, mainly as a separate structure. This allows us to completely
ignore the MDIO bus attached to a stmmac if desired, and not create
the PHY bus. It also allows the stmmac driver to use a different PHY
from the one it is connected to, for example a fixed PHY or bit banging
PHY.
Also derive the stmmac/PHY connection type (MII/RMII etc) from the
mode can be passed into <platf>_configure_ethernet.
STLinux kernel at git://git.stlinux.com/stm/linux-sh4-2.6.32.y.git
provides several examples how to use this new infrastructure (that
actually is easier to maintain and clearer).

This patch add the missing dma_unmap().
Which solved the critical issue of system freeze on heavy load.
Michal Miroslaw's rejected patch:
[PATCH v2 10/46] net: jme: convert to generic DMA API
Pointed out the issue also, thank you Michal.
But the fix was incorrect. It would unmap needed address
when low memory.
Got lots of feedback from End user and Gentoo Bugzilla.
