Laczen opened a new issue, #15972:
URL: https://github.com/apache/nuttx/issues/15972

   ### Description / Steps to reproduce the issue
   
   When using udp over sixlowpan the processing of udp packets can generate a 
icmpv6 response when icmpv6 is enabled. These responses are not handled 
properly.
   
   To reproduce: setup 2 nodes for sixlowpan communication (e.g. using espnow).
   
   Use udpclient to send packets from one node to a "server" node (without 
enabling udpserver).
   The server node will block.
