net/ice/base: avoid single-member variable-length structs

There are a number of structures that consist of a one-element array as the

Others are used to index into a buffer/array consisting of a variable
number of a different data or structure type.  Those are unnecessary since

net/ice/base: split capabilities discovering

replace ice_discover_caps with two functions that each take a pointer to

This makes the side effect of updating the hw->dev_caps and
hw->func_caps obvious from reading the implementation of the function.
Additionally, it opens the way for enabling reading of device
capabilities outside of the initialization flow. By passing in
a pointer, another caller will be able to read the capabilities without

common/iavf: use pad byte to specify MAC type

Currently, there is no way for a VF driver to specify that it wants to
change its device/primary unicast MAC address. This makes it
difficult/impossible for the PF driver to track the VF's device/primary
unicast MAC address, which is used for VM/VF reboot and displaying on
the host. Fix this by using 2 bits of a pad byte in the
virtchnl_ether_addr structure so the VF can specify what type of MAC
it's adding/deleting.

Below are the values that should be used by all VF drivers going
forward.

VIRTCHNL_ETHER_ADDR_LEGACY(0):
- The type should only ever be 0 for legacy AVF drivers (i.e.
  drivers that don't support the new type bits). The PF drivers
  will track VF's device/primary unicast MAC using with best
  effort.

VIRTCHNL_ETHER_ADDR_PRIMARY(1):
- This type should only be used when the VF is changing their
  device/primary unicast MAC. It should be used for both delete
  and add cases related to the device/primary unicast MAC.

VIRTCHNL_ETHER_ADDR_EXTRA(2):
- This type should be used when the VF is adding and/or deleting
  MAC addresses that are not the device/primary unicast MAC. For
  example, extra unicast addresses and multicast addresses
  assuming the PF supports "extra" addresses at all.

If a PF is parsing the type field of the virtchnl_ether_addr, then it
should use the VIRTCHNL_ETHER_ADDR_TYPE_MASK to mask the first two bits
of the type field since 0, 1, and 2 are the only valid values.

Exposing 'struct eth_dev_ops' to applications is bad because it is a

   because of the hardware constraint, we need implement unmmapping
   relationship configurations by binding all queues to the last
   interrupt vector and reserving the last interrupt vector. This
   results in a decrease of the maximum queues when upper applications
   call the rte_eth_dev_configure API function to enable Rx interrupt.
2) And for another versions, such as kunpeng 930, hns3 PMD driver can
   map/unmmap all interrupt vectors with queues when Rx interrupt is
   enabled.

This patch resolves configuration differences about Rx interrupts based
on kunpeng 920 and kunpeng 930.
