Re: [lwip-users] LLDP Implementation for lwIP

[Amit Ashara]

Hello Simon

I can make the change for lldp_raw to be netif compliant and using internal functions in the lldp.c to construct the packet.

Will it be OK in that case (along with the single port requirement)

Regards

Amit

That's not netif-portable. A netif driver has to implement netif_linkoutput_fn(struct netif *netif, struct pbuf *p)
and there's no source MAC address passed. You can check the pbuf of course, but that's not acceptable
for all TX packets.

You can do that but you would limit the use of such a protocol implementation.
