The bnx2x_select_queue() was using __skb_tx_hash() to select the
transmit queue, totally ignoring XPS settings, while XPS can help
performance quite significantly, so change the bnx2x_select_queue()
to use __dev_pick_tx() instead which will use XPS if configured.

Forcing uninitialized state allows us to upgrade and reinitialize the adapter.

FW_VERSION_T4 = 1.4.0.0
FW_VERSION_T5 = 0.0.0.0
At this point driver supports above and greater than above version of firmware.
If it doesn't find the required firmware version than it forces the adapter to
be reinitialized as shown below.

1) If FW_ON_ADAPTER < FW_VERSION and we're the MASTER_PF force uninitialized
   state and a FW upgrade if available.

       - If FW_ON_ADAPTER < /lib/firmware/cxgb4/t*fw.bin we will update the
         adapters FW.
       - If FW_ON_ADAPTER >= /lib/firmware/cxgb4/t*fw.bin don't upgrade FW.
       - If upgrade_fw() fails force reinitialization of the adapter anyways,
         it might still work.

   Either way forcing the uninitialized state allows cxgb4 reinitialize FW.

2) If FW_ON_ADAPTER >= FW_VERSION driver follows normal path.

The Allwinner A10 has an ethernet controller that seem to be developped
internally by them.

The exact feature set of this controller is unknown, since there is no
public documentation for this IP, and this driver is mostly the one
published by Allwinner that has been heavily cleaned up.

Ethernet controllers found on Kirkwood SoCs not only suffer from loosing
MAC address register contents on clock gating but also some important
registers are reset to values that would break ethernet. This patch
clears the CLK125_BYPASS_EN bit for DT enabled Kirkwood only by using
of_device_is_compatible() instead of #ifdefs. Non-DT Kirkwood is not
affected as it installs a clock gating workaround because of the MAC
address issue above. Other Orion SoCs do not suffer from register reset,
do not have the bit in question, or do not have the register at all.
Moreover, system controllers on PPC using this driver should also be
protected from clearing that bit.
