Hi

of this LPM table but, when it comes to multithreaded application, I read the

Hello dpdk-dev,
I understand that the reserved memzones cannot be freed, as mentioned in
the DPDK specs. But I would like to know why? Is there any limitations?
If the memory is not freed/returned, then can it be reused for subsequent
allocations without re-init (i.e. with same memzone name)?

Hi Maciej
Did you solve your problem? I meet this problem as your case. And I
found avail_idx(in rte_vhost_dequeue_burst function) is always zero although I
do send packets in VM.

Stephen,
The enic debug flag is off by default. So it is going to print the
