[GitHub] [nuttx] michi-jung commented on issue #8833: w5500 ethernet can not work well

   The w5500 driver uses the chip in MACRAW mode, i.e. only at the Ethernet level.  All IP processing is done by NuttX's networking stack.  This is why only the MAC is written to a chip register and why only 'socket0' is used to exchange raw Ethernet frames.

   Do you mean that you extended the code to write the e.g. the netmask gateway into the W5500's registers?  This does not make sense for the MACRAW mode.
