This patchset introduces some improvements on socionext netsec driver. 
 - patch 1/2, avoids unneeded MMIO reads on the Rx path 
 - patch 2/2, is adjusting the numbers of descriptors used

Changes since v1:
 - Move dma_rmb() to protect descriptor accesses until the device 
 has updated the NETSEC_RX_PKT_OWN_FIELD bit

Ilias Apalodimas (2):
  net: socionext: Use descriptor info instead of MMIO reads on Rx
  net: socionext: Increase descriptors to 256
