Subject: [PATCH net-next v2 8/8] r8169:update rtl8168f rev.b pcie ephy parameter

RTL8168F rev.B does not have to set following two ephy parameters.
{ 0x06, 0x00c0,	0x0020 }
{ 0x08, 0x0001,	0x0002 }

Add function rtl_hw_start_8168f_2 to set RTL8168F rev.B ephy parameters,
instead of using function rtl_hw_start_8168f_1.
