Tnat's why strange bugs appears if we use Jumbo packets more than 8KB. E.g ospf daemon of Quagga fails to send route updates: Nov 23 18:59:42 multiped ospfd[16187]: *** sendmsg in ospf_write to 224.0.0.6 failed with Message too long >How-To-Repeat: >Fix: Workaround: adjust net.inet.raw.maxdgram to bigger value. It will be nice if committers will increase defult buffer size as hotfix. >Release-Note: >Audit-Trail: >Unformatted:
