net: stmmac: Add HW descriptor prefetch setting for DWMAC Core 5.20 onwards
DWMAC Core 5.20 onwards supports HW descriptor prefetching. Additionally, it also depends on platform specific RTL configuration. This capability could be enabled by setting DMA_Mode bit-19 (DCHE). So, to enable this cability, platform must set plat->dma_cfg->dche = true and the DWMAC core version must be 5.20 onwards. Else, this capability wouldn`t be configured Signed-off-by: Mohammad Athari Bin Ismail <mohammad.athari.ismail@intel.com> Signed-off-by: David S. Miller <davem@davemloft.net>
