Hi Kieran: When will you release new lwIP with stable IPv6 version? Could IPv6 work with IPv4 together ? if not, how to switch automatically ?

Support for zero-copy DMA drivers (RX and TX) with netconn API :-) On RX, I used CORE_LOCKING=1 CORE_LOCKING_INPUT=1 PBUF_REF custom pbuf with custom free function Simon wrote: > For the RX side, using a *custom* PBUF_REF would be the best solution. > That's a pbuf that has a 'freed' callback and references external > memory.

I haven't found how to make TX work without copying the frame before sending, yet. -- Regards. _______________________________________________ lwip-users mailing list lwip-users@nongnu.org https://lists.nongnu.org/mailman/listinfo/lwip-users _______________________________________________ lwip-users mailing list lwip-users@nongnu.org https://lists.nongnu.org/mailman/listinfo/lwip-users
