Per the Linux Kernel coding style, as enforced by the kernel
checkpatch script, pointers should not be explicitly compared to
NULL. Therefore within wlan_cfg replace any such comparisons with
logical operations performed on the pointer itself.

In datapath, some of the messages get printed everytime when packet
is received or sent. This situation ends up in excessive logging which
leads to stability issue.
In order to fix the situation, provide knob through INI to control
excessive logging and create new macro for logging the message which
comes under per packet path.

Eanable monitor mode low water mark interrupt.The monitor
mode processing is stuck in the monitor mode buffer ring full
if monitor mode low water mark interrupt is not enabled.This
is because there is no packet come in when monitor buffer
ring is full and hence there is no ppdu end interrupt.The
monitor is not processing the monitor ring and buffer ring
full condition is not remoevd.

- Support to pass IPA enabled(disabled) flag from ini to DP layer
- Use ioremap call to translate tx_comp_doorbell_paddr obtained from
calling ipa_setup api to tx_comp_doorbell_vaddr. This is needed to
write the initial value of HP at the doorbell address.
- Change REO_DST_RING_SIZE and WLAN_CFG_TX_RING_SIZE to 1023
for napier/hastings if IPA is enabled. This is needed because,
ipa_setup API can handle only 16-bit values for the size param(bytes)
of the ring.
- Disable hash based flow steering for SAP peers in case IPA is enabled
and set default reo_dest_ring_4 as default RX ring. Since IPA will be
reaping RX packets from reo_dest_ring_4 only, flow steering is not
needed for SAP peers.
- Unmap pre-allocated TX buffers for IPA in the TX completion ring.
- Donot execute IPA functionality if IPA is disabled from ini.
