Fw: [lwip-users] IP-options and TCPs "urgend data"

[Masta Slader]

Hi!

I am interessted in "urgend data" mechanism, which specify data that is more
important than other data in the stream.
It is also important for me to know, if all "MUST" IP-Options are included
in LWIP. I think there is no IP-Option included, but I am not sure!?!

Thanks!
Christian
