[PATCH v6 net-next 2/7] net: mvneta: Do not allocate buffer in rxq init with HWBM

From: Gregory CLEMENT
Date: Thu Dec 01 2016 - 12:04:16 EST


For HWBM all buffers are allocated in mvneta_bm_construct() and in runtime
they are put into descriptors by hardware. There is no need to fill them
at this point.
