If anyone has any objections, please let me know. ------------------ From: Lorenzo Bianconi [ Upstream commit 6b8fed2675fb75d23e6cf2b7e49c94926e884b34 ] The core software reset issued in stmmac_init_dma_engine() during ndo_open() callback clears the MTL RX packet parser registers, but stmmac_rxp_config() is only invoked from the cls_u32 add/delete paths. After an ifdown/ifup cycle the hardware therefore runs with the default all-pass table while priv->tc_entries still reports the filters as installed. Re-apply the RX packet parser table from priv->tc_entries in stmmac_hw_setup(), right after the software reset, so the filters are restored when the interface is brought up again.
