1848b117cc app/testpmd: fix RSS key for flow API RSS rule
When a flow API RSS rule is issued in testpmd, device RSS key is changed
unexpectedly, device RSS key is changed to the testpmd default RSS key.

Consider the following usage with testpmd:
1. first, startup testpmd:
 testpmd> show port 0 rss-hash key
 RSS functions: all ipv4-frag ipv4-other ipv6-frag ipv6-other ip
 RSS key: 6D5A56DA255B0EC24167253D43A38FB0D0CA2BCBAE7B30B477CB2DA38030F
          20C6A42B73BBEAC01FA
2. create a rss rule
 testpmd> flow create 0 ingress pattern eth / ipv4 / udp / end \
          actions rss types ipv4-udp end queues end / end

3. show rss-hash key
 testpmd> show port 0 rss-hash key
 RSS functions: all ipv4-udp udp
 RSS key: 74657374706D6427732064656661756C74205253532068617368206B65792
          C206F76657272696465

This is because testpmd always sends a key with the RSS rule,
if user provides a key as part of the rule that key is used, if user
doesn't provide a key, testpmd default key is sent to the PMDs, which is
causing device programmed RSS key to be changed.

There was a previous attempt to fix the same issue [1], but it has been
reverted back [2] because of the crash when 'key_len' is provided
without 'key'.

This patch follows the same approach with the initial fix [1] but also
addresses the crash.

After change, testpmd RSS key is 'NULL' by default, if user provides a
key as part of rule it is used, if not no key is sent to the PMDs at all

command VIRTCHNL_OP_CONFIG_VSI_QUEUES cannot send the message only once
to configure up to 256 queues. In this patch, we send the messages
multiple times to make sure that the buffer size is less than 4K each
time.

e436cd4383 net/iavf: negotiate large VF and request more queues
Negotiate large VF capability with PF during VF initialization. If large
VF is supported and the number of queues larger than 16 is required, VF
requests additional queues from PF. Mark the state that large VF is
supported.

If the allocated queues number is larger than 16, the max RSS queue
region cannot be 16 anymore. Add the function to query max RSS queue
region from PF, use it in the RSS initialization and future filters
configuration.

ef807926e1 net/iavf: support requesting additional queues from PF
Add a new virtchnl function to request additional queues from PF.
Current default queue pairs number when creating a VF is 16. In order to
support up to 256 queue pairs per VF, enable this request queues
function.

When requesting queues succeeds, PF will return an event message. If it
is handled by interrupt first, the request queues command cannot receive
the correct PF response and will wait until timeout. Therefore, disable
interrupt before requesting queues in order to handle the event message
asynchronously.

5e03e316c7 net/iavf: handle virtchnl event message without interrupt
Currently, VF can only handle virtchnl event message by calling
interrupt.
It is not available in two cases:
1. If the event message comes during VF initialization before interrupt
   is enabled, this message will not be handled correctly.
2. Some virtchnl commands need to receive the event message and handle
   it with interrupt disabled.

To solve this issue, we add the virtchnl event message handling in the
process of reading vitchnl messages in adminq from PF.
