The driver is already allocating receive buffers of 2KiB and the Ethernet MAC is configured to accept frames up to UMAC_MAX_MTU_SIZE.

Do you want to treat the SYSTEMPORT Lite differently? /* Set maximum frame length */ if (!priv->is_lite) umac_writel(priv, UMAC_MAX_MTU_SIZE, UMAC_MAX_FRAME_LEN); else gib_set_pad_extension(priv);
