This series is mainly adding support for RSS to Virtio PMD
driver. The two last patches are fixing an issue in testpmd
that could cause out of bounds access, and fix
an issue spotted in the mlx5 driver while looking for
inspiration.

The first motivation for this series is to eventually
support RSS down to the Vhost-user library, so that OVS can
benefit from it. But it will be also useful with vDPA
devices in the future.

Regarding the testing, I have tested it with qemu v5.2 from
Fedora 34. Since libvirt does not support yet enabling RSS
feature in the Qemu virtio-net device, and this feature is
disabled by default, the tester can either rebuild the qemu
package to enable it by default or use the qemu cmdline to
do the same.

The tester can use testpmd in icmpecho mode in the guest
and scapy on the host to inject random traffic on the tap
interface, e.g.:
sendp(Ether(src=RandMAC()) / IP(src=RandIP(), dst='192.168.123.9') / UDP(sport=RandShort(), dport=RandShort()), loop=True, iface='vnet7')

Then it can play with RSS config in testpmd to change the
RETA, or hash type and see traffic being steered
accordingly by checking the Rx xstats.

Changes in v3:
==============
- Add applying user-specified RSS conf a device config time (Andrew)
- Remove useless checks (Chenbo)
- Clean control message payload dlen variable (Chenbo)
- Add GTPU offload type (Xiaoyun)
- Add missing types to str2flowtype() (Xiaoyun)

Changes in v2:
==============
- Rework patch 2 to keep old behaviour, but fix possible out of bounds due to key length (Andrew/Nelio/Xiaoyun)
- s/reta/RETA/ (Andrew)
- Applied A-by on patch 3 (Slava)
- Fix display of configured hash types
- Add missing flow types definition to testpmd's port info command

Provide the capability to update the hash key, hash types
and RETA table on the fly (without needing to stop/start
the device). However, the key length and the number of RETA
entries are fixed to 40B and 128 entries respectively. This
is done in order to simplify the design, but may be
revisited later as the Virtio spec provides this
flexibility.

Note that only VIRTIO_NET_F_RSS support is implemented,
VIRTIO_NET_F_HASH_REPORT, which would enable reporting the
packet RSS hash calculated by the device into mbuf.rss, is
not yet supported.

Regarding the default RSS configuration, it has been
chosen to use the default Intel ixgbe key as default key,
and default RETA is a simple modulo between the hash and
the number of Rx queues.

port_rss_hash_key_update() initializes rss_conf with the
RSS key configuration provided  by the user, but it calls
rte_eth_dev_rss_hash_conf_get() before calling
rte_eth_dev_rss_hash_update(), which overrides the parsed
RSS config.

While the RSS key value is set again after, this is not
the case of the key length. It could cause out of bounds
access if the key length parsed is smaller than the one
read from rte_eth_dev_rss_hash_conf_get().

This patch restores the key length before the
rte_eth_dev_rss_hash_update() call to ensure the RSS key
value/length pair is consistent.
