Occasionally, the amount of packets to free from the work queue ends perfectly on a boundary to have nb_free = 0 and pool = 0. This causes a segfault as follows: (gdb) bt #0 rte_mempool_default_cache #1 rte_mempool_put_bulk (n=0, obj_table=0x7f10deff2530, mp=0x0) #2 enic_free_wq_bufs (wq=wq@entry=0x7efabffcd5b0, completed_index=completed_index@entry=33) #3 0x00007f11e9c86e17 in enic_cleanup_wq (enic=<optimized out>, wq=wq@entry=0x7efabffcd5b0) at /usr/src/debug/openvswitch-2.6.1/dpdk-16.11/drivers/net/enic/enic_rxtx.c:442 #4 0x00007f11e9c86e5f in enic_xmit_pkts (tx_queue=0x7efabffcd5b0, tx_pkts=0x7f10deffb1a8, nb_pkts=<optimized out>) at /usr/src/debug/openvswitch-2.6.1/dpdk-16.11/drivers/net/enic/enic_rxtx.c:470 #5 0x00007f11e9e147ad in rte_eth_tx_burst (nb_pkts=<optimized out>, tx_pkts=0x7f10deffb1a8, queue_id=0, port_id=<optimized out>) This commit makes the enic wq driver match other drivers who call the bulk free, by checking that there are actual packets to free.

When defining two failsafe devices in testpmd the port numbers of the failsafe devices may not be consecutive. For example: if failsafe device includes a PCI device and a TAP device then failsafe port numbers would be 0 and 3. Port 0 - failsafe #1 device Port 1 - PCI #1 device Port 2 - TAP #1 device Port 3 - failsafe emmericp#2 device Port 4 - PCI emmericp#2 device Port 5 - TAP emmericp#2 device If forwarding is defined between the failsafe devices including a peer address the forwarding should be between peer addresses of ports 0 and 3. Instead testpmd establishes forwarding between peer addresses of consecutive ports 0 and 1. This commit fixes this bug.
