Hi
Today i had a closer look at the abis pcap file (which i sent on Friday). For me one thing is "strange" but i don't know if this is a normal behavior. Is it OK that sometimes a packet contains 2 sub-packets? For instance:
this is valid behavior (and you see it during RSL/OML bring up), one thing how this can break (and would break OpenBSC/libosmo-abis) is that we do:
1.) ipa_header = recv(3 bytes) 2.) data = recv(ipa_header->len)
this would fail in case header and data do not appear on the same frame. So the esoteric question is do you have MTU changes in your network (this assumes that the ipaccess would have similar broken code we have)?
