[ Upstream commit 5aa48279712e1f134aac908acde4df798955a955 ]
Change the minimum value of RX/TX descriptors to 64 to enable setting the rx/tx value between 64 and 80. All igc devices can use as low as 64 descriptors. This change will unify igc with other drivers. Based on commit 7b1be1987c1e ("e1000e: lower ring minimum size to 64")
