> Sorry, I missed this comment. Yes, the correct value that only enables the port is 0x00002000. The rest of the bits are set to 1 because they are reserved and default values. Since this patch changes the way l2qsys_reg->sys.switch_port_mode[i] is set (out_le32() replaced by setbits_le32()), the other bits are no longer touched when enabling the port:
OK. This is (obviously) unclear as is.
