Subject: net: dont update dev->trans_start in 10GB drivers

Followup of commits 9d21493b4beb8f918ba248032fefa393074a5e2b
and 08baf561083bc27a953aa087dd8a664bb2b88e8e
(net: tx scalability works : trans_start)
(net: txq_trans_update() helper)

Now that core network takes care of trans_start updates, dont do it
in drivers themselves, if possible. Multi queue drivers can
avoid one cache miss (on dev->trans_start) in their start_xmit()
handler.

Exceptions are NETIF_F_LLTX drivers (vxge & tehuti)

Subject: qlge: Add support for varied pcie function numbers.

Currently we support only PCIe NIC functions zero and one, and FCoE
functions as 3 and 4. Future configurations can mix these up in any
fashion.
This patch removes the 0-1 dependancy and allows usage of any of the 4
functions. We also find the alternate NIC function (if exist) and
determine our port number based on the comparison of the two functions:
Lower function number gets first port, higher function gets second port.

Subject: qlge: Relax alignment on TX harware queue.

The alignment was on size of queue boundary, but the hardware
only requires 4-byte alignment.

Subject: qlge: Allow RX buf rings to be > than 4096 bytes.

RX buffer rings can be comprised of non-contiguous fixed
size chunks of memory. The ring is given to the hardware
as a pointer to a location that stores the location of
the queue.  If the queue is greater than 4096 bytes then
the hardware gets a list of said pointers.
This patch addes the necessary logic to generate the list if
the queue size exceeds 4096.
