The field txNumDeferred is used by the driver to keep track of the number of packets it has pushed to the emulation. The driver increments it on pushing the packet to the emulation and the emulation resets it to 0 at the end of the transmit. There is a possibility of a race either when (a) ESX is under heavy load or (b) workload inside VM is of low packet rate. This race results in xmit hangs when network coalescing is disabled. This change creates a local copy of txNumDeferred and uses it to perform ring arithmetic.
