Commit c477d044 added support for RGMII
rx/tx delays except that it ends up clearing rx/tx delays bit for modes
differents that RGMII*ID. Due to this, ethernet is not working anymore
on my guruplug server +. This patch is fixing that.

The FCoE offload is enabled/disabled per adapter, but upper FCoE protocol
stack could have multiple FCoE instances created on the same physical network
interface, e.g., FCoE on multiple VLAN interfaces on the same physical
network interface. In this case we want to turn on FCoE offload at the first
request from ndo_fcoe_enable() but only turn off FCoE offload at the very last
call to ndo_fcoe_disable(). This is fixed by adding a refcnt in the per adapter
FCoE structure and tear down FCoE offload when refcnt decrements to zero.

Current ixgbe stats have following problems :

- Not 64 bit safe (on 32bit arches)

- Not safe in ixgbe_clean_rx_irq() :
   All cpus dirty a common location (netdev->stats.rx_bytes &
netdev->stats.rx_packets) without proper synchronization.
   This slow down a bit multiqueue operations, and possibly miss some
updates.

Fixes :

Implement ndo_get_stats64() method to provide accurate 64bit rx|tx
bytes/packets counters, using 64bit safe infrastructure.

ixgbe_get_ethtool_stats() also use this infrastructure to provide 64bit
safe counters.

The smsc95xx driver currently generates a new random MAC address
every time the interface is brought up. This makes it impossible to
override using the standard `ifconfig hw ether` approach.

Past patches tried to make the MAC address a module parameter or
base it off the die ID, but it seems to me much simpler (and
hopefully less controversial) to stick with the current random
generation scheme, but allow the user to change the address.

This patch does exactly that - it moves the random address
generation from smsc95xx_reset() into smsc95xx_bind(), so that it is
done once on module load, not on every ifup. The user can then
override this using the standard mechanisms.

Applies against 2.6.35 and linux-2.6 head.
