a718007f03 qcacmn: increment vdev refcount for search by id
Add new API dp_vdev_get_ref_by_id() which will return vdev
pointer by holding a reference. Caller of this API has
to ensure that this reference is released by calling
dp_vdev_unref_delete() API

New lock soc->vdev_map_lock is introduced to protect
vdev id to object array

27f16faa4d qcacmn: Exclude HTT metadata length when not in use during TX
Currently, when an extension descriptor is used during TX datapath, we
use HTT metadata length + msdu extension descriptor length, even we
do not fill HTT meta data. This is inefficient and hardware will end up
doing DMA of extra HTT metadata, even when not needed.
Include length of metadata in TCLdata command only if HTT metadata is
filled in.

e2b00339f3 qcacmn: add APIs to iterate the peers at vdev level
Add new APIs to iterate through the vdev peer list
by taking the peer reference.

A call back has to be passed to these APIs which will
be called for every peer in the lisst

dp_vdev_iterate_peer() -> iterates through peer_list of vdev
dp_pdev_iterate_peer() -> iterates through peer_list of all
                          vdevs in pdev
dp_soc_iterate_peer() -> iterates through peer_lists of all vdevs
                         in soc

Additonal APIs are added to for itearations where the callback
will be called outside the vdev->peer_list_lock, as these APIs
have additional memory allocations suggested to use only in case
the iteration need to happen outside lock

dp_vdev_iterate_peer_lock_safe()
dp_pdev_iterate_peer_lock_safe()
dp_soc_iterate_peer_lock_safe

6159db7efa qcacmn: Reset tx desc as part of flow pool delete
Tx desc flow pool for the vdev is not deleted as part
of disconnection due to tx_desc pending to be processed
in tx comp ring. Hdd_stop is triggered immediately after
this causing dp vdev detach. In parallel, the tx desc
from the tx comp ring is processed, wherein stale vdev
address is derefernced to get dp soc causing page fault.

Fix is to reset tx desc by setting the vdev to NULL as
part of dp_tx_delete_flow_pool and also reset count to
zero in dp_tx_comp_handler before ring desc process loop.

This framework can be extended for new feature addition
which set filters for the monitor status and monitor
