Subject: [PATCH 02/11] net: calxedaxgmac: read correct field in xgmac_desc_get_buf_len

From: Rob Herring <rob.herring@...xeda.com>

xgmac_desc_get_buf_len appears to have a copy/paste error. flags is the
wrong field to read. We should be reading buf_size field. cpu_to_le32
should also be le32_to_cpu. This never really mattered as this function
is only used for DMA mapping calls which happen to be nops with coherent
DMA.
