Update of bug #30185 (project lwip):

                  Status:               Need Info => Postponed              


Follow-up Comment #1:

The main problem here is that we don't have the information for unix-style
FIONREAD (size of next packet): we only have the total amount of bytes queued
in the recvmbox.

We would need some kind of 'peek-into-mbox' function to solve this without
great overhead if unused.
