SM_SW_FWD_EN can be overriden using hardware straps, which is probably the reason why it is already set after reset for your case and why you are seeing leakage. Ideally the bootloader would have cleared that bit to make sure it puts the switch back into unconfigured managed mode and avoid the leakage. If you have some way to access the MII registers in CFE, try to clear that bit and see if the leakage still happens? -- Florian _______________________________________________ openwrt-devel mailing list [email protected] https://lists.openwrt.org/cgi-bin/mailman/listinfo/openwrt-devel
