Hi Florian,

Not sure I completely understand your suggestion, do you mean that I
should break down the body of that function above such that there are
per-speed lower level functions? Something like the pseudo-code below:

genphy_set_test() {
	switch (mode) {
	case PHY_STD_TEST_MODE_100BASET2_1:
	..
	case PHY_STD_TEST_MODE_100BASET2_3:
		return genphy_set_100baset2();

	case PHY_STD_TEST_MODE_1000BASET_1:
	..
	case PHY_STD_TEST_MODE_1000BASET_4:
		return genphy_set_1000baset();

	case PHY_STD_TEST_MODE_8021BWQCQ_1:
		return genphy_set_100baset1();

}

Yes, I should write pseudo code. Sorry about confusion.
User can override this function or expand to other modes.

Thanks.
