Seems OVS-DPDK still missing IP fragmentation support, is there any schedule to have it?<o:p></o:p></p>

I'm transferring to use OVN, but for those nodes which have external network connection, they may face this problem,<o:p></o:p></p>

except to configure Jumbo frames, is there any other workaround?<o:p></o:p></p>

I am not clear on the situation however.<o:p></o:p></p>

You mention about configuring jumbo frames which means you can avoid the fragments by doing this ?<o:p></o:p></p>

If this is true, then this is the best way to proceed since performance will be better.<o:p></o:p></p>

<p class="MsoNormal" style="margin-left:.5in">It's good but it's limited can't be guaranteed, so I am asking is there any other way without IP fragmentation so far. <o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">It sounds like you want to avoid IP fragmentation; so far so good.<o:p></o:p></p>
