vq is allocated on pairs, hence we should do pair reallocation
at numa_realloc() as well, otherwise an error like following
occurs while do numa reallocation:
VHOST_CONFIG: reallocate vq from 0 to 1 node
PANIC in rte_free():
Fatal error: Invalid memory
The reason we don't catch it is
We could first check if we need realloc vq or not, if so,
reallocate it. We then do similar to vhost dev realloc.
This could get rid of the tons of repeated "if (realloc_dev)"
and "if (realloc_vq)" statements, therefore, makes code
a bit more readable.

While we use a single linked list to maintain all devices, we could
use a static array to achieve the same goal, just like what we did
to maintain the eth devices with rte_eth_devices array. This could
simplifies the code a bit.

In fm10k_recv_scattered_pkts function, a packet is stored in a linked list,
offload flags such as PKT_RX_VLAN_PKT should be set in the first segment.

Hi!
I would like to know which functions (classification, crypto, ...) can be
performed in hardware with DPDK ?
For classification, I have read that Intel 82599 does it in hardware, are there
many other NIC that can make classification in hardware or is this card the
only one ?

Hi Thomas,
Any comments on this patch set?
This patch set have been fully reviewed and tested, but it has not applied in
DPDK2.2.
Let me know if you still have some concerns, if not, I will rebased it and send
a version.
