+Description:
+		The driver will pad NCM Transfer Blocks (NTBs) longer
+		than this to tx_max, allowing the device to receive
+		tx_max sized frames with no terminating short
+		packet. NTBs shorter than this limit are transmitted
+		as-is, without any padding, and are terminated with a
+		short USB packet.
+
+		Padding to tx_max allows the driver to transmit NTBs
+		back-to-back without any interleaving short USB
+		packets.  This reduces the number of short packet
+		interrupts in the device, and represents a tradeoff
+		between USB bus bandwidth and device DMA optimization.
+
+		Set to 0 to pad all frames. Set greater than tx_max to
+		disable all padding.
