Try adding the device ID 0x1050 to the relevant case in ether82557.c
and let me know what happens, e.g.

		switch(p->did){
		default:
			continue;
		case 0x1031:		/* Intel 82562EM */
		case 0x1050:		/* */
		case 0x2449:		/* Intel 82562ET */
			nop =3D 1;
			/*FALLTHROUGH*/
		case 0x1209:		/* Intel 82559ER */
		case 0x1229:		/* Intel 8255[789] */
			break;
		}

There may be bugs/features to be worked around, but I think it's just
another variant of the 82557 embedded in a hub.
