I am using lwip socket api (v1.8)

What should "(v1.8)" mean here?

with freertos on a zedboard and
discovered that lwip_recv won't receive certain udp broadcast packages.
Whole broadcasts (ip.dest=255.255.255.255) work fine, as well as
unicasts. However subnet broadcasts (ip.dest=192.168.0.255 and
netmask: /24) don't. They're not handled by lwip. Did anyone else
stumbled upon this behaviour?

None that I know of. Would you mind filing a bug report so that this
doesn't get forgotten?

Thanks,
Simon
