[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
