Hi, I use FreeBSD 9.0 Beta2 on two computers . One have one wireless card, and the other one has two wireless card.
When I use sctp with the feature of automatic address reconfiguration , I notice that no Asconf Chunk send. Here are INIT chunk message about association: Both in the INIT chunk and INIT ACK chunk , the Supported Extensions Parameter field indicates that ASCONF, ASCONF-ACK, FORWARD-TSN, PKTDROP, STREAM_RESET and AUTH are supported. So I think it will be ok ,if I use sctp_bindx() to bind a ip address, but no ASCONF chunk shows in Wireshark. After that ,I recompiled the kernel with the option of debug enable, in the file from dmesg ，I notice that kernel get the new ip address ,but it does not send this ASCONF CHUNK. Here are messages: 192.168.1.50 is the new ip address that I want to bind to the association.
