[lwip-users] pbuf flag definition: PBUF_FLAG_LINK_BROADCAST

[Kevin]

Hi, all:

I find a pbuf flag in lwip1.1.0: which is as this:
#define PBUF_FLAG_LINK_BROADCAST 0x80U

I assume it flags a broadcast message in the pbuf. Right?

While in lwip1.3.0, I cannot find this flag. My question is:
How lwip1.3.0 tells that it is a broadcast message in pbuf? Is there a relevant flag for broadcast message?

Thanks!

Regards,
Kevin

At least that's what the comment said it would...

I'm not totally sure why this flag has been deleted two year ago, but I
don't recall it being used in the lwIP code (I think the only protocol
that needs this information is ARP, and that can figure it out on its own).
