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
shinfo->nr_frags to determine if we need to unmap a received skb.  By doing
this we can avoid a cache miss on small packets since the buffer_info
structure should already be prefetched.

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.

The result of container_of should not be NULL.  In particular, in this case
the argument to the enclosing function has passed though INIT_WORK, which
dereferences it, implying that its container cannot be NULL.

A simplified version of the semantic patch that makes this change is as
follows:

.init sections are discarded.  Otherwise (if also having HOTPLUG=y)
unbinding and binding a device to the driver via sysfs will result in an
oops as does a device being registered late.

Various other functions that are called by mac_sonic_probe need to move
to .devinit.text, too.
