[PATCH v3 0/4] sched: cleanup of sched library

[Megha Ajmera <megha.ajmera@intel.com>]

v3:
This patchset involves the cleanup of sched library:

* Addresses review comments on v2 patchset.

* RTE_SCHED_CMAN is left unmodified in rte_config.h.
  Cleanup of this will be taken up later.

* Removed unused flag RTE_SCHED_VECTOR from arm/meson.build. Only
  scalar version is now supported.

* Added grinder configuration in docs. The configuration is moved from
  rte_config.h into sched library.  Default number of grinders is 8.
  To override the default, specify RTE_SCHED_PORT_N_GRINDERS=N in CFLAGS
  before compiling sched library.

* Sample app is updated to always collect statistics as this flag is
  removed.

* Updated softnic library by enabling TC oversubscription.
  This flag is now removed from sched.

v2:
This patchset involves the cleanup of sched Library:

* Removed unused sched #defines from rte_config.
  RTE_SCHED_CMAN, RTE_SCHED_COLLECT_STATS, RTE_SCHED_SUBPORT_TC_OV and
  RTE_SCHED_VECTOR.

* RTE_SCHED_COLLECT_STATS flag is removed from the code.
  Stats collection is now always enabled.

* RTE_SCHED_SUBPORT_TC_OV flag is removed.
  TC over subscription for best effort queues is now always enabled.

* RTE_SCHED_VECTOR flag is removed from sched library as the code under this
  flag is no longer useful. Only scalar version is supported.

* Rebased with latest main branch code.

Megha Ajmera (4):
  sched: remove code no longer needed
  sched: move grinder configuration flag
  sched: enable statistics unconditionally
  sched: enable traffic class oversubscription unconditionally
