My test reports memory leaks for receive path, looking at the code, it seems
the following allocations were never released, should they? Thanks.

Hi, Maxime
I met one issue with your patch set during the v17.11 test.
The test scenario is following,
1. Bind one NIC, use test-pmd set vhost-user with 2 queue
usertools/dpdk-devbind.py --bind=igb_uio :05:00.0
./x86_64-native-linuxapp-gcc/app/testpmd -c 0xe -n 4 --socket-mem 1024,1024 \
--vdev 'net_vhost0,iface=vhost-net,queues=2' - -i --rxq=2 --txq=2 --nb-cores=2
--rss-ip
2. Launch qemu with virtio device which has 2 queue
3. In VM, launch testpmd with virtio-pmd using only 1 queue.
x86_64-native-linuxapp-gcc/app/testpmd -c 0x07 -n 3 - -i --txqflags=0xf01 \
--rxq=1 --txq=1 --rss-ip --nb-cores=1
First,
commit 09927b5249694bad1c094d3068124673722e6b8f
vhost: translate ring addresses when IOMMU enabled
The patch causes no traffic in PVP test. but link status is still up in
vhost-user.
Second,
eefac9536a901a1f0bb52aa3b6fec8f375f09190
vhost: postpone device creation until rings are mapped
The patch causes link status "down" in vhost-user.
Could you have a check at your side? Thanks.
