Protocol agnostic flow offloading in Flow Director is enabled by this
patch based on the Parser Library, using existing rte_flow raw API.
Note that the raw flow requires:
1. byte string of raw target packet bits.
2. byte string of mask of target packet.
Here is an example:
FDIR matching ipv4 dst addr with 1.2.3.4 and redirect to queue 3:
flow create 0 ingress pattern raw \
pattern spec \
00000000000000000000000008004500001400004000401000000000000001020304 \
pattern mask \
000000000000000000000000000000000000000000000000000000000000ffffffff \
/ end actions queue index 3 / mark id 3 / end
Note that mask of some key bits (e.g., 0x0800 to indicate ipv4 proto)
is optional in our cases. To avoid redundancy, we just omit the mask
of 0x0800 (with 0xFFFF) in the mask byte string example. The prefix
'0x' for the spec and mask byte (hex) strings are also omitted here.
Also update the ice feature list with rte_flow item raw.

rte_flow_action_handle_create() did not mention what happens
with an indirect action when a device is stopped and started again.
It is natural for some indirect actions, like counter, to be persistent.
Keeping others at least saves application time and complexity.
However, not all PMDs can support it, or the support may be limited
by particular action kinds, that is, combinations of action type
and the value of the transfer bit in its configuration.
Add a device capability to indicate if at least some indirect actions
are kept across the above sequence. Without this capability the behavior
is still unspecified, and application is required to destroy
the indirect actions before stopping the device.
In the future, indirect actions may not be the only type of objects
shared between flow rules. The capability bit intends to cover all
possible types of such objects, hence its name.
Declare that the application can test for the persistence
of a particular indirect action kind by attempting to create
an indirect action of that kind when the device is stopped
and checking for the specific error type.
This is logical because if the PMD can to create an indirect action
when the device is not started and use it after the start happens,
it is natural that it can move its internal flow shared object
to the same state when the device is stopped and restore the state
when the device is started.
Indirect action persistence across a reconfigurations is not required.
In case a PMD cannot keep the indirect actions across reconfiguration,
it is allowed just to report an error.
Application must then flush the indirect actions before attempting it.

Previously, it was not specified what happens to the flow rules
when the device is stopped, possibly reconfigured, then started.
If flow rules were kept, it could be convenient for application
developers, because they wouldn't need to save and restore them.
However, due to the number of flows and possible creation rate it is
impractical to save all flow rules in DPDK layer. This means that flow
rules persistence really depends on whether PMD and HW can implement it
efficiently. It can also be limited by the rule item and action types,
and its attributes transfer bit (a combination of an item/action type
and a value of the transfer bit is called a rule feature).
Add a device capability bit for PMDs that can keep at least some
of the flow rules across restart. Without this capability behavior
is still unspecified and it is declared that the application must
flush the rules before stopping the device.
Allow the application to test for persistence of rules using
a particular feature by attempting to create a flow rule
using that feature when the device is stopped
and checking for the specific error.
This is logical because if the PMD can to create the flow rule
when the device is not started and use it after the start happens,
it is natural that it can move its internal flow rule object
to the same state when the device is stopped and restore the state
when the device is started.
Rule persistence across a reconfigurations is not required,
because tracking all the rules and configuration-dependent resources
they use may be infeasible. In case a PMD cannot keep the rules
across reconfiguration, it is allowed just to report an error.
Application must then flush the rules before attempting it.

Since v0.4.0, if the underlying kernel supports it, libbpf uses 'bpf
link' to manage the programs on the interfaces of the xsks. This has two
repercussions for the PMD.
1. In the case where the PMD asks libbpf to load the default XDP
program, the PMD no longer needs to remove it on teardown. This is
because bpf link handles the unloading under the hood.
2. In the case where the PMD loads a custom program, libbpf expects this
program to be linked via bpf link prior to creating the socket.
This patch introduces probes for the libbpf version and kernel support
for bpf link and orchestrates the loading and unloading of
programs according to the capabilities of the kernel and libbpf. The
libbpf version is checked with meson and pkg-config. The probe for
kernel support mirrors how it is implemented in libbpf. A bpf_link is
created and looked up on loopback device. If successful, bpf_link will
be used for the AF_XDP netdev.

The RSS expansion algorithm is using a graph to find the possible
expansion paths. A graph node with the 'explicit' flag will be skipped,
if it is not found in the flow pattern.
The current implementation misses a check for the explicit flag when
expanding the pattern according to ETH item with EtherType.
For example:
testpmd> flow create 0 ingress pattern eth / ipv6 / udp / vxlan / eth
type is 2048 / end actions rss level 2 types udp end / end
The "eth type is 2048" item in the pattern may be expanded to "ETH IPv4".
The ETH node in the expansion graph is followed by VLAN node marked as
explicit. The fix is to skip the VLAN node and continue the expansion
with its next nodes, IPv4 and IPv6.
The expansion paths for the above example will be:
ETH IPV6 UDP VXLAN ETH END
ETH IPV6 UDP VXLAN ETH IPV4 UDP END
