Hello:

This patch was applied to netdev/net.git (main)
by Paolo Abeni [off-list ref]:

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.
