This is done by adding support for independent pbl for tx/rx through DT. More fine grained tuning of pbl is possible thanks to a DT property saying that we should NOT multiply pbl values by x8/x4 in hardware. All new DT properties are optional, and created in a way that it will not affect any existing DT configurations. Changes since V1: Created cover-letter. Rebased patch set against next-20161205, since conflicting patches to stmmac_platform.c has been merged since V1. Changes since V2: Moved default value initialization of pbl to stmmac_platform.c and added a check for pbl != 0 in stmmac_main.c, to catch a possble pbl == 0 from pci glue. ==================== Signed-off-by: David S.
