It is 5708 B1, and due to some hardware limitations, ethtool initiated
WoL is not supported.  Here's the code fragment in bnx2.c:

	if ((CHIP_ID(bp) == CHIP_ID_5708_A0) ||
	    (CHIP_ID(bp) == CHIP_ID_5708_B0) ||
	    (CHIP_ID(bp) == CHIP_ID_5708_B1) ||
	    !(REG_RD(bp, BNX2_PCI_CONFIG_3) & BNX2_PCI_CONFIG_3_VAUX_PRESET)) {
		bp->flags |= BNX2_FLAG_NO_WOL;
		bp->wol = 0;
	}
