Re: [dpdk-users] Help with mbuf and mempool
Thank you – The rte_eal_init() function helped to resolve the compile error.

Also char buf[PATH_MAX] is not initialised or assigned any value. Assign a name
to it.
The PATH_MAX need not be 4096, use a lesser value say 100.

Subject: [dpdk-users] Help with mbuf and mempool
Hello,
I am trying to allocate an mbuf to use for IP fragmentation. When instantiating
a mempool using rte_pktmbuf_pool_create() function, I keep getting the
following error message.
Error Message:
* MEMPOOL: Cannot allocate tailq entry!
Will you please let me know what I am missing?

Katie

Re: [dpdk-users] Help with mbuf and mempool
Hi,
You are using Socket 0, and might be there is no memory in this socket or no
memory left in this socket 0. Try with SOCKET_ID_ANY.

Subject: [dpdk-users] Help with mbuf and mempool
Hello,
I am trying to allocate an mbuf to use for IP fragmentation. When instantiating
a mempool using rte_pktmbuf_pool_create() function, I keep getting the
following error message.
Error Message:
* MEMPOOL: Cannot allocate tailq entry!
Will you please let me know what I am missing?
Regards,
Katie
