Btw, a few extra identifiers in rtl_init_rxcfg may improve consistency:

           missing             |          included
-------------------------------+-------------------------------
RTL_GIGA_MAC_VER_36 (8168f)    | RTL_GIGA_MAC_VER_35 (8168f)
RTL_GIGA_MAC_VER_38 (RTL8411)  | RTL_GIGA_MAC_VER_44 (RTL8411)
RTL_GIGA_MAC_VER_39 (RTL8106e) | RTL_GIGA_MAC_VER_43 (RTL8106e)
RTL_GIGA_MAC_VER_37 (RTL8402)  |
