This patch fixes "overwrite" problem. without this fix, SFP I2C EEPROM
data, which is located at A0 can be overwritten by the phy write function.

Instead of using the multi_tx_table to map possible Tx queues to Tx rings
we can just do simple subtraction for the unlikely event that the Tx queue
provided exceeds the number of Tx rings.

Since igb only uses advanced descriptors we might as well just use an IGB
specific define and drop the _ADV suffix for the descriptor declarations.
In addition this can be further reduced by assuming that it will be working
on pointers since that is normally how the Tx descriptors are handled.

Many of the function names in the hot path are carrying an extra "_adv"
suffix on the end of them to represent the fact that they are using
advanced descriptors instead of legacy descriptors. However since all igb
uses are advanced descriptors adding the extra suffix doesn't really add
any additional data. Since this is the case it is easiest to just drop the
suffix and save us from having to store the extra characters.

This change is meant to be a general cleanup and performance improvement
for clean_rx_irq. The previous patch should have updated the allocation so
that the rings can be treated as read-only within the clean_rx_irq
function. In addition I am re-ordering the operations such that several
goals are accomplished including reducing the overhead for packet
accounting, reducing the number of items on the stack, and improving
overall performance.

This change is meant to improve performance by splitting the Tx and Rx
rings into 3 sections. The first is primarily a read only section
containing basic things like the indexes, a pointer to the dev and netdev
structures, and basic information. The second section contains the stats
and next_to_use and next_to_clean values. The third section is primarily
unused values that can just be placed at the end of the ring and are not
used in the hot path.
The adapter structure has several sections that are read in the hot path.
In order to improve performance there I am combining the frequent read
hot path items into a single cache line.

This change is meant to streamline the Rx buffer allocation and cleanup.
This is accomplished by reducing the number of writes by only having the Rx
descriptor ring written by software during allocation, and it will only be
read during cleanup.

This change removes support for single buffer mode from igb and makes the
driver function in packet split always. The advantage to doing this is
that we can reduce total memory allocation overhead significantly as we
will only need to allocate one 1K slab per packet and then make use of a
reusable half page instead of allocating a 2K slab per packet.

This patch modifies the max_frame_size in order account for an optional
VLAN tag. In order to support this we must also increase the
MAX_STD_JUMBO_FRAME_SIZE to account for the 4 extra bytes.

Use IFF_UNICAST_FTL to find out if driver handles unicast address
filtering. In case it does not, promisc mode is entered.
Patch also fixes following drivers:
stmmac, niu: support uc filtering and yet it propagated
ndo_set_multicast_list
bna, benet, pxa168_eth, ks8851, ks8851_mll, ksz884x : has set
ndo_set_rx_mode but do not support uc filtering
