The kernel you mailed me can't work well, cause it is a scsi driver.
So I don't have a real test on my board. But you can try the following way:
in src/sys/pci/if_wm.c
1.
	/*
	 * Toggle the LSB of the MAC address on the second port
	 * of the i82546.
	 */
	if (sc->sc_type == WM_T_82546 || sc->sc_type == WM_T_82546_3) {
//		if ((CSR_READ(sc, WMREG_STATUS) >> STATUS_FUNCID_SHIFT) & 1)
		pci_decompose_tag(pc, pa->pa_tag, NULL, NULL, &function);
		if (function == 1)
		{
			enaddr[5] ^= 1;
			CSR_WRITE(sc, WMREG_STATUS, CSR_READ(sc,
WMREG_STATUS) | 0x04);
		}
	}
2.

//	if (cfg1 & EEPROM_CFG1_ILOS)
//		sc->sc_ctrl |= CTRL_ILOS;
	sc->sc_ctrl &= ~(0x1 << 21);

then you can ping a host(A) from the host(B)  with the new kernel to test if
the PHY can send the packets out.
for example, sniffer the packets on host A, if the driver is OK, you can
receive the ARP request packet from host B.

Any question, plx feel free to contact me.
