Hi all,
I get a EINVAL since DPDK 16.07 when trying to allocate a mempool with rte_pktmbuf_pool_create. This is when I use --no-huge --vdev=eth_ring0. But this happens before accessing the virtual device in any ways.
Which, btw shows the documentation is wrong as it indicates :
EINVAL - cache size provided is too large, or priv_size is not aligned.
Which is not the problem here (tried cache_size of 0, 64,256 and priv_size is 0). EINVAL can obviously come from elswhere.
Any idea? Something changed in involved subsystems since 16.07?
Thanks,
Tom
