Propagation from qcacld-2.0 to qcacld-3.0.
Initially, when a packet is forwarded from txrx layer, it is added in
count only once although the count should increase by 2 as there is one
rx packet and one tx packet that is not getting considered in the hdd
packet count.
Add code to ensure that when packet is forwarded from lower layers,

In lpm qos voting, no. of packets or bytes sent or received in a
particular amount of time is recorded and decision of disabling
or enabling lpm is done based on that. These packets are recorded
in HDD layer. In case when packets are forwarded to tx only, packets
don't come upto HDD layer and so in case of intra bss forwarding,
lpm qos voting is not being executed appropriately.
Add code to calculate the intra bss forwarded packets in txrx layer
and update them in calculating lpm qos voting.

A race condition has been observed between outgoing TX traffic and
peer deletion when DUT has concurrent SAP(DBS) and STA sessions in 5G
and 2G respectively and the peer connected to SAP moves away triggering
peer deletion at DUT. Due to peer being deleted, the vdev corresponding
to the peer is void which results in a crash in ol_tx_data function
while trying to send Tx data.
Fix crash by checking for a null vdev in ol_tx_data.

If lro_disable is called after cds_close, which is the case
for module unloads, then many of the pointers used in dereg
sequence are NULL (CE_state, hif, txrx_pdev). There is a case,

the service is not in the table. Add logs for cases where either

qdf_wait_single_event expects msecs as the timeout value.
However, two references in dp, second of which is this instance,
passes the value in ticks. This causes the value to be converted
to msecs a second time by the function and hence an incorrect
timeout value.
The other instance is in the qcacmn project.

During IBSS session tear down, we are hitting a lockup. The issue is
seen as the pdev->peer_ref_mutex is being taken up twice in
ol_txrx_remove_peers_for_vdev and ol_txrx_peer_unref_delete. The later
function gets invoked by the former and hence we are stuck while trying
to acquire the spinlock, the second time.
Fix issue by releasing peer_ref_mutex lock before invoking
callback (wma_remove_peer) in ol_txrx_remove_peers_for_vdev function.

During peer unmap handler, while the peer is being deleted, there is a
possible race condition if the OL Rx thread is processing RX packets
and accesses the peer structure after its contents have been nulled.
Remove race condition by -
* Flush all RX packets in ol_txrx_peer_detach function which happens
before peer unmap event is received from firmware
* Avoid use of peer data structures (for example peer->local_id)
outside of peer->info_lock in ol_rx_data_cb function. Use cached
local copies of peer data structures instead
