Peer id mismatch is observed when prefetch of HW
descriptor exceeds the last valid descriptor.
To fix this issue, add check to limit prefetch to
the last valid descriptor.

Currently if txrx_peer is NULL in Tx completion or rx process
band update will not happen, which will result in invalid band
issue during connectivity logging.
To fix the issue maintain local link id and use link id to
find link peer and update band information in nbuf cb
based on peer frequency.

Currently SW writes a magic number in the tx completion
ring descriptor after reaping from the ring. This magic
number is used to determine, if the HP of the srng has been
updated without the contents of the ring descriptor has been
written.
There were cases of such stale entries observed and as a SW
workaround, add a logic to wait for a specific timeout for
the contents of the ring descriptor to be updated before
moving on to process subsequent ring entries.

Issue is: During roaming when tx completion status for M2/M4 frames
are received before peer_id mapping is done, opmode is left to its
default value QDF_MAX_NO_OF_MODE. Because of this opmode value
connectivity log is skipped.
Fix is: In tx completion status path, if peer is NULL then derive
the vdev from the tx descriptor vdev_id, extract and set op_mode.

In the case of MLO sta connection existing API won't be able
to find the mld peer resulting a traffic failure.
Use wrapper API to fetch the peer in multipass TX processing
which will search for both legacy and mld peer.

Currently before calling the stats_cbk we do not
check if the vdev has been deleted or not. There is
a case where vdev might be deleted (but not freed due
to pending ref-count) and the osif_vdev will be freed
as a part of the delete sequence. In this case, calling
stats_cbk with dangling pointer to osif_vdev will lead
to an access to memory which has been freed.
To mitigate this issue, check if the vdev has been marked
for deletion, before calling the stats_cbk in tx completion
path.

Optimize tx completion processing in fastpath by adding the list of
tx descs to the free list directly instead of individually accessing
each descriptor and adding it to free list. This gives advantages of
not taking descriptor pool lock for each descriptor and rather takes
the lock only once when appending the whole list of descs to the
free list.
Also removed unused member shinfo_addr from tx_desc structure. Removal
of this member enables increase of flags type from u16 to u32 without
increasing the size of tx_desc structure. These changes improved peak
KPI by 2% in SFE mode.

1. In lowmem profiles the number of tx_desc in 4th pool is reduced to
quarter for memory optimizations.
Added new API dp_get_updated_tx_desc which will return the desc value
from INI based on the flag DP_TX_DESC_POOL_OPTIMIZE.
2. Changes to introduce new INI to get reduced desc value for 4th tx
desc pool.
This helps optimize 0.75M per SOC in lowmem profiles.

This flag DP_TX_EXT_DESC_POOL_OPTIMIZE if enabled will reduce the number
of ext tx desc pool to 1.
1. Changes done to split the tx_desc and ext_tx_desc pool number
variables in alloc and free path. Based on this flag the reduced
ext_desc_pool count will be returned.
2. In Tx path, since the pool id is selected based on the CPU, changes done
to override the desc_pool_id of ext_desc_pool via new API
dp_tx_ext_desc_pool_override to 0 with which from whatever core the packets
comes from, pool 0 will be chosen for ext_desc.

The to_fw bit in HW descriptor is not set for exception

exception marked skb.

Currently the packet tx handling for AP-multipass
assumes wlan repeater to be present. For targets like
qca6490, kiwi etc, wlan repeaters are not supported in
the network topology.
Hence to skip unwanted tx packet copy in per-pkt path,
move the code to handle packet tx to waln repeater in
multipass mode under a feature macro.
