[PATCH v5 3/5] bnx2x: restructure Tx routine

[Rasesh Mody]

 - Process Tx completions based on configured Tx free threshold and
   determine how much TX BDs are required before invoking bnx2x_tx_encap()
 - Change bnx2x_tx_encap() to void function

[PATCH v5 4/5] bnx2x: use single doorbell for TX

[Rasesh Mody]

Change the Tx routine to ring the doorbell once per burst
and not on every Tx packet. This driver-level optimization
is necessary to achieve line rates for larger frame
sizes (1k or more).

Fix icc warning:
error #188: enumerated type mixed with another type

Fixed the code for simple cases caused the warning.
Still need to disable compiler warning because of more complex case.

This bnx2x patch and a qede one cannot be merged in master tree
because of an API change:
	http://dpdk.org/commit/bd6aa172
	http://dpdk.org/commit/e2aae1c1
Please could you rework this patch for RC2?

Sorry for the inconvenience, I should have caught it earlier.
We'll try to synchronize the branches more often in future.
