The error is normally centered around the issue that no memory was allocated for socket 0 or all of the memory was consumed by previous allocations. To support jumbo frames I did need to increase the packet info structure to hold the largest frame. Please check to see if you can increase the amount of memory for socket 0 and socket 1 if you have two to see if that fixes the problem. I may have to rework this make jumbo frame support more dynamic. > > Best, > Frank > > > On Fri, Nov 29, 2019 at 4:03 PM Wiles, Keith <keith.wi...@intel.com> wrote: > > > > On Nov 19, 2019, at 6:47 PM, Frank Li <frank.li...@gmail.com> wrote: > > > > Current IPv6 functionality in pktgen is broken.
