0edf18eee2 sched: add 64-bit values
To support high bandwidth network interfaces, all rates (port,
subport level token bucket and traffic class rates, pipe level
token bucket and traffic class rates) and stats counters defined
in public data structures (rte_sched.h) are modified to support
64 bit counters.

18218713bf enforce experimental tag at beginning of declarations
Putting a '__attribute__((deprecated))' in the middle of a function
prototype does not result in the expected result with gcc (while clang
is fine with this syntax).

$ cat deprecated.c
void * __attribute__((deprecated)) incorrect() { return 0; }
__attribute__((deprecated)) void *correct(void) { return 0; }
int main(int argc, char *argv[]) { incorrect(); correct(); return 0; }
$ gcc -o deprecated.o -c deprecated.c
deprecated.c: In function ‘main’:
deprecated.c:3:1: warning: ‘correct’ is deprecated (declared at
deprecated.c:2) [-Wdeprecated-declarations]
 int main(int argc, char *argv[]) { incorrect(); correct(); return 0; }
 ^

Move the tag on a separate line and make it the first thing of function
prototypes.
This is not perfect but we will trust reviewers to catch the other not
so easy to detect patterns.

sed -i \
     -e '/^\([^#].*\)\?__rte_experimental */{' \
     -e 's//\1/; s/ *$//; i\' \
     -e __rte_experimental \
     -e '/^$/d}' \
     $(git grep -l __rte_experimental -- '*.h')

Special mention for rte_mbuf_data_addr_default():

There is either a bug or a (not yet understood) issue with gcc.
gcc won't drop this inline when unused and rte_mbuf_data_addr_default()
calls rte_mbuf_buf_addr() which itself is experimental.
This results in a build warning when not accepting experimental apis
from sources just including rte_mbuf.h.

For this specific case, we hide the call to rte_mbuf_buf_addr() under
the ALLOW_EXPERIMENTAL_API flag.

c1656328db meter: replace color definitions
This patch implements the changes proposed in the deprecation
note[1]. Replace multiple color definitions in various places such as
rte_meter.h, rte_tm.h and rte_mtr.h with single rte_color defined
in rte_meter.h.

This is simple search and replace exercise without any implementation
change.

5d3f721009 mbuf: implement generic format for sched field
This patch implements the changes proposed in the deprecation
notes [1][2].

librte_mbuf changes:
The mbuf->hash.sched field is updated to support generic
definition in line with the ethdev traffic manager and meter APIs.
The new generic format contains: queue ID, traffic class, color.

Added public APIs to set and get these new fields to and from mbuf.

librte_sched changes:
In addtion, following API functions of the sched library have
been modified with an additional parameter of type struct
rte_sched_port to accommodate the changes made to mbuf sched field.
(i)rte_sched_port_pkt_write()
(ii) rte_sched_port_pkt_read_tree_path()

librte_pipeline, qos_sched UT, qos_sched app are updated
to make use of new changes.

Also mbuf->hash.txadapter has been added for eventdev txq,
rte_event_eth_tx_adapter_txq_set and rte_event_eth_tx_adapter_txq_get()
are updated to use mbuf->hash.txadapter.txq.

doc:
Release notes updated.
Removed deprecation notice for mbuf->hash.sched and sched API.

4726fb245e sched: add post-init pipe profile API
Add new API function to add more pipe configuration profiles
post initialization to the set of exisitng profiles specified during
the creation of scheduler port.

This API removes the current limitation that forces the user
to define the full set of pipe profiles as the part of port parameters
while port is being created.

320d0b6ea0 sched: hide structure of port hierarchy
Right now the scheduler hierarchy is encoded as a bitfield
that is visible as part of the ABI. This creates an barrier
limiting future expansion of the hierarchy.

As a transistional step. hide the actual layout of the hierarchy
and mark the exposed structure as deprecated. This will allow for
expansion in later release.

ea672a8b16 mbuf: remove the rte_pktmbuf structure
The rte_pktmbuf structure was initially included in the rte_mbuf
structure. This was needed when there was 2 types of mbuf (ctrl and
packet). As the control mbuf has been removed, we can merge the
rte_pktmbuf into the rte_mbuf structure.

Advantages of doing this:
  - the access to mbuf fields is easier (ex: m->data instead of m->pkt.data)
  - make the structure more consistent: for instance, there was no reason
    to have the ol_flags field in rte_mbuf
  - it will allow a deeper reorganization of the rte_mbuf structure in the
    next commits, allowing to gain several bytes in it
