Allow the user to set the symmetric Toeplitz hash function via:
# ethtool -X eth0 hfunc toeplitz symmetric-xor
The driver will reject any new RSS configuration if a field other than
(IP src/dst and L4 src/dst ports) is requested for hashing.
The symmetric RSS will not be supported on PFs not advertising the ADV RSS
Offload flag (ADV_RSS_SUPPORT()), for example the E700 series (i40e).

Add new VIRTCHNL_VF_OFFLOAD_RX_FLEX_DESC flag, opcode
VIRTCHNL_OP_GET_SUPPORTED_RXDIDS and add member rxdid
in struct virtchnl_rxq_info to support AVF Flex RXD
extension.
Add support to allow VF to query flexible descriptor RXDIDs supported
by DDP package and configure Rx queues with selected RXDID for IAVF.
Add code to allow VIRTCHNL_OP_GET_SUPPORTED_RXDIDS message to be
processed. Add necessary macros for registers.

Add support for the VF driver to be able to request
VIRTCHNL_VF_OFFLOAD_VLAN_V2, negotiate its VLAN capabilities via
VIRTCHNL_OP_GET_OFFLOAD_VLAN_V2_CAPS, add/delete VLAN filters, and
enable/disable VLAN offloads.
VFs supporting VIRTCHNL_OFFLOAD_VLAN_V2 will be able to use the
following virtchnl opcodes:
VIRTCHNL_OP_GET_OFFLOAD_VLAN_V2_CAPS
VIRTCHNL_OP_ADD_VLAN_V2
VIRTCHNL_OP_DEL_VLAN_V2
VIRTCHNL_OP_ENABLE_VLAN_STRIPPING_V2
VIRTCHNL_OP_DISABLE_VLAN_STRIPPING_V2
VIRTCHNL_OP_ENABLE_VLAN_INSERTION_V2
VIRTCHNL_OP_DISABLE_VLAN_INSERTION_V2
Legacy VF drivers may expect the initial VLAN stripping settings to be
configured by the PF, so the PF initializes VLAN stripping based on the
VIRTCHNL_OP_GET_VF_RESOURCES opcode. However, with VLAN support via
VIRTCHNL_VF_OFFLOAD_VLAN_V2, this function is only expected to be used
for VFs that only support VIRTCHNL_VF_OFFLOAD_VLAN, which will only
be supported when a port VLAN is configured. Update the function
based on the new expectations. Also, change the message when the PF
can't enable/disable VLAN stripping to a dev_dbg() as this isn't fatal.
When a VF isn't in a port VLAN and it only supports
VIRTCHNL_VF_OFFLOAD_VLAN when Double VLAN Mode (DVM) is enabled, then
the PF needs to reject the VIRTCHNL_VF_OFFLOAD_VLAN capability and
configure the VF in software only VLAN mode. To do this add the new
function ice_vf_vsi_cfg_legacy_vlan_mode(), which updates the VF's
inner and outer ice_vsi_vlan_ops functions and sets up software only
VLAN mode.

Currently, RSS hash input is not available to AVF by ethtool, it is set
by the PF directly.
Add the RSS configure support for AVF through new virtchnl message, and
define the capability flag VIRTCHNL_VF_OFFLOAD_ADV_RSS_PF to query this
new RSS offload support.

Declare bitmap of allowed commands on VF. Initialize default
opcodes list that should be always supported. Declare array of
supported opcodes for each caps used in virtchnl code.
Change allowed bitmap by setting or clearing corresponding
bit to allowlist (bit set) or denylist (bit clear).
