On some cases, dp_rx_thread can not handle nbufs in time,
then a large number of packets are pending in
rx_thread->nbuf_queue, which run out of system memory at
last and failed to malloc new buffers for refill buffer
ring, fw crash is encountered. To avoid this, drop RX
packets when the pending number becomes large.

Currently there is a single INI item tcp_udp_checksumoffload to enable
or disable this feature for all the adapters. In some cases, we want to
be able to enable this feature selectively for NAN mode.
Add nan_tcp_udp_checksumoffload ini item to enable or disable checksum
offload feature specifically for NAN mode. If
nan_tcp_udp_checksumoffload is 'true' and tcp_udp_checksumoffload is
false, hardware checksum offload will be enabled only for the NAN
adapter and not for other adapters.

1) Modified MSI interrupt mask for QCN9000 so that rx and tx
interrupts can be decoupled.
2) Removed lmac interrupts from polling mode and switched
them to msi interrupts. Added MSI masks for lmac rings.
3) Enable monitor mode LWM interrupt. This was already enabled in
integrated ahb interrupts but missing in msi. Replenish buffers in
RXDMA refill ring based on low threshold interrupts in addition to
regular Rx processing. Also made interrupt batch counter threshold as 8
for monitor status ring since ppdu end interrupts are not available in
PCI chipset and require srng msi interrupts to reap monitor status ring

pdev_id is being initialized with 0. Since 0 is valid pdev_id, though

1. Currently, mapping multiple rings to same interrupt

processing under different interrupt masks.

mode processing is stuck in the monitor mode buffer ring full

- 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.
