60702e8c7c bpf: add extra information for external symbol definitions
Extend struct rte_bpf_xsym with new fields to provide information about:
 - for variables - type and size
 - for functions - number of arguments and type/size of each argument
   and return value

Such information would allow validate code to perform
more extensive checking on input BPF program and catch
misbehaving BPF code.

That change would cause ABI/API breakage for librte_bpf.

bfc828d295 eventdev: improve error handling for Rx adapter queue add/del
The new WRR sequence applicable after queue add/del is set
up after setting the new queue state, so a memory allocation
failure will leave behind an incorrect state.

This change separates the memory sizing + allocation for the
Rx poll and WRR array from calculation of the WRR sequence.
If there is a memory allocation failure, existing Rx queue
configuration remains unchanged.

e30dd31847 service: add mechanism for quiescing
Existing service functions allow us to stop a service, but doing so doesn't
guarantee that the service has finished running on a service core. This
commit introduces rte_service_may_be_active(), which returns whether the
service may be executing on one or more lcores currently, or definitely is
not.

The service core layer supports this function by setting a flag when
a service core is going to execute a service, and unsetting the flag when
the core is no longer able to run the service (its runstate becomes stopped
or the lcore is no longer mapped).

With this new function, applications can set a service's runstate to
stopped, then poll rte_service_may_be_active() until it returns false. At
that point, the service is quiesced.

b166d4f30b gso: support UDP/IPv4 fragmentation
This patch adds GSO support for UDP/IPv4 packets. Supported packets
may include a single VLAN tag. UDP/IPv4 GSO doesn't check if input
packets have correct checksums, and doesn't update checksums for
output packets (the responsibility for this lies with the application).
Additionally, UDP/IPv4 GSO doesn't process IP fragmented packets.

UDP/IPv4 GSO uses two chained MBUFs, one direct MBUF and one indrect
MBUF, to organize an output packet. The direct MBUF stores the packet
header, while the indirect mbuf simply points to a location within the
original packet's payload. Consequently, use of UDP GSO requires
multi-segment MBUF support in the TX functions of the NIC driver.

If a packet is GSO'd, UDP/IPv4 GSO reduces its MBUF refcnt by 1. As a
result, when all of its GSOed segments are freed, the packet is freed
automatically.

d292a42fc8 build: fix for host clang and cross gcc
The following error hits if host cc compiler is clang(default one in most
linux distributions) and the cross compiler is gcc.

The root cause is: the hybride compilers add the warning options to the
meson project as project arguments, which apply for both host compiling and
cross compiling. But some options such as '-Wno-format-truncation' are not
supported nor recognized by clang, so they have to be removed from the
project arguments for the host compiler to run smoothily and added back as
cflags for the cross compiler to compile for cross source files.

The fix is remove unrecognized warning options from the meson project
arguments shared by gcc and clang, as add them specifically for gcc or
clang as cflags.

db10602b76 cryptodev: add min headroom and tailroom requirement
Enabling crypto devs to specify the minimum headroom and tailroom it
expects in the mbuf. For net PMDs, standard headroom has to be honoured
by applications, which is not strictly followed for crypto devs. This
prevents crypto devs from using free space in mbuf (available as
head/tailroom) for internal requirements in crypto operations. Addition
of head/tailroom requirement will help PMDs to communicate such
requirements to the application.

The availability and use of head/tailroom is an optimization if the
hardware supports use of head/tailroom for crypto-op info. For devices
that do not support using the head/tailroom, they can continue to operate
without any performance-drop.

2d349f6034 cryptodev: rename experimental private data APIs
The name private_data is confusing in these APIs:
rte_cryptodev_sym_session_set_private_data()
rte_cryptodev_sym_session_get_private_data()
It refers to data added at the end of the session hdr for
use by the application.
The session already contains sess_private_data[index]
which is used to store private pmd data and most references to private
data refer to that.
e.g. external apis
rte_cryptodev_sym_get_private_session_size() and internal
set/get_session_private_data() refer to sess_private_data[].

So rename to user_data, i.e.
rte_cryptodev_sym_session_set_user_data()
rte_cryptodev_sym_session_get_user_data()

This field was useful when the session mempool was created inside

Most PMDs do not have a limitation on the sessions managed,
