Tony Nguyen says:

====================
Change MIN_TXD and MIN_RXD to allow set rx/tx value between 64 and 80

Olga Zaborska says:

Change the minimum value of RX/TX descriptors to 64 to enable setting the rx/tx
value between 64 and 80. All igb, igbvf and igc devices can use as low as 64
descriptors.
