Hi, I am seeing an MBUF issue between two threads communicating using a Ring of MBUFs. I would appreciate if someone can tell if this is correct method to accomplish this:
1. Master Core creates MBUF pool and a ring. 2. An EAL Transmit thread polls this Ring 3. A NON EAL threads allocates a MBUF from this pool and queues in the ring 4. EAL Transmit thread deques and transmits the MBUF Here is the issue I am seeing: In NON EAL Thread where MBUF is allocated, the mbuf dump shows : dump mbuf at 0x7f3b9339aa80, phys=11339ab00, buf_len=2176 pkt_len=34, ol_flags=f0000000000000, nb_segs=1, in_port=1 segment at 0x7f3b9339aa80, data=0x7f3b9339ab80, data_len=34 In Transmit thread on dequeuing; dump mbuf at 0x7f3b9339ab00, phys=0, buf_len=0 pkt_len=0, ol_flags=0, nb_segs=0, in_port=0 So mbuf address is messed up and none of the other values are good. Any idea, suggestion most welcome. Should I be only using EAL thread to send to Ring but that is highly limiting in design Regards, Neeraj
