This change resolves some warnings seen with DMA debugging enabled in which
we were mapping skb->data with size + NET_IP_ALIGN and unmapping it with

The igb driver is currently initializing the mailbox function pointers
after the phy. This causes issues as the phy init will return from the
function early if there is no phy present.
To resolve this I have moved the function pointer init to a location prior
to the phy initialization so that serdes based adapters can also make use
of SR-IOV.

This change makes it so that we use buffer_info->dma instead of

this we can avoid a cache miss on small packets since the buffer_info

This update cleans up the receive address register initialization. The
main purpose of this is to clean out some redundancy that was introduced
due to having multiple ways of setting the receive address registers.
Instead of having a specialized function to set one register and one to set
all of them it makes more sense to just go through the list calling the
function that is needed to set the individual registers.

Certain types of control packets (LLDP, LACP, etc.) are not supposed to have a
priority tag or vlan tag inserted. Ixgbe driver is currently priority
tagging everything (if packet is not on a VLAN interface).
This patch modifies DCB mode, so that packets marked with skb priority
TC_PRIO_CONTROL are not priority tagged. It also transmits these packets on
the highest priority traffic class.
Programs (like dcbd) can set the skb priority using a socket option. Or, a tc
filter can be configured to set the priority value. Using the value
TC_PRIO_CONTROL (7) has the benefit that it is already defined in the kernel,
and the bonding LACP code already sets the skb->priority field to this value.
