The send_packets() function was using ring->cur as index to scan the transmit ring. This function may also set ring->cur ahead of ring->head, in case no more slots are available. However, the function also uses nm_ring_space() which looks at ring->head to check how many slots are available. If ring->head and ring->cur are different, this results in pkt-gen advancing ring->cur beyond ring->tail. This patch fixes send_packets() (and similar source locations) to use ring->head as a index, rather than using ring->cur. MFC after: 1 week
