net/hns3: fix deleting default VLAN from PF
Currently, the default VLAN (vlan id 0) will never be deleted from the
hardware VLAN table based on hns3 PF device. As a result, even a
non-zero PVID is set by calling rte_eth_dev_set_vlan_pvid based on hns3
PF device, packets with VLAN 0 and without VLAN are still received by PF
driver in Rx direction.
This patch deletes the restriction that VLAN 0 cannot be removed in PVID
configuration to ensure packets without PVID will be filtered when PVID
is set. And the patch adds VLAN 0 to the soft list when initializing
vlan configuration to ensure that VLAN 0 will be deleted from the
hardware VLAN table when device is closed.

net/hns3: add VLAN configuration compatibility
Because of hardware limitation based on the old version of hns3 network
engine, there are some restrictions:
a) HNS3 PMD driver needs select different processing mode for VLAN based
on whether PVID is set which means our driver need sense the PVID
states.
b) For packets transmitting process, only two layer of VLAN tag is
supported. If the total number of VLAN tags in mbuf and VLAN offload
by hardware (VLAN insert by descriptor) exceeds two, the VLAN in mbuf
will be overwritten by VLAN in the descriptor.
c) If port based VLAN is set, only one VLAN header is allowed in mbuf or
it will be discard by hardware.
In order to solve these restriction, two change is implemented on the
new versions of network engine.
1) add a new VLAN tagged insertion mode, named tag shift mode;
2) add a new VLAN strip control bit, named strip hide enable;
The tag shift mode means that VLAN tag will shift automatically when the
inserted place has a tag. For PMD driver, the VLAN tag1 and tag2
configurations in Tx side do not need to be considered because the
hardware completes it. However, the related configuration will still be
retained to be compatible with the old version of network engine.
The VLAN strip hide means that hardware will strip the VLAN tag and hide
VLAN in descriptor (VLAN ID exposed as zero and related STRIP_TAGP is
off).
These changes make it no longer necessary for the hns3 PMD driver to be
aware of the PVID status and have the ability to send mult-layer (more
than two) VLANs packets. Therefore, hns3 PMD driver introduces the
concept of VLAN mode and adds a new VLAN mode named HNS3_PVID_MODE to
indicate that PVID-related IO process can be implemented by the
hardware. And VF driver does not need to be modified because the related
mailbox messages will not be sent by PF kernel mode netdev driver under
new network engine and all the related hardware configuration is on the
PF side.

representors for endpoints that are not in the same host domain,
additional dev args have been in the PMD like so:
rep-based-pf=<physical index> rep-is-pf=<VF=0 or PF=1>

that the representor is derived off of.
Since representor(s) can be created for endpoint PFs as well,
rename struct bnxt_vf_representor to bnxt_representor and other such
dev_ops and function names.
devargs have also been extended to specify the exact CoS queue along
with flow control enablement to be used for the conduit between the
representor and the endpoint function.

net/ena/base: split RSS function and hash getters
There is no need to keep single function for both hash function and
the key. If the caller want's to get only single value, then it had to

Except reading functions from the device, one can also use function
