during unloading the driver.

In dp_rx_get_free_desc_list() corrected the

rx_desc are not available in the pool

When reaping rx monitor msdu in dp_rx_mon_mpdu_pop, if msdu_ppdu_id >
ppdu_id, then the corresbonding dp_rx_desc will not be added to free list,
and in_use flag still is 1 but it has done nbuf unmap which linked
to this rx desc. meantime, if rmmod triggered then it will go through the
rx desc pool and unmap the linked nbuf that in_use flag is 1, panic
happened. add unmapped flag checking to avoid double unmap.

In attach and replenish path, nbuf maps a DMA region for device access.
But the DMA region mapped is not unmapped in detach path.
Fix is to unmap the DMA region when rx_desc_pool is freed.

Replenish buffers in RXDMA refill ring based on low threshold
interrupts in addition to regular Rx processing. Also increased
RXDMA refill ring size to 4096.

Add a in_use flag to identify if a rx desc is associated
with a valid nbuf and use this flag while freeing the nbuf.

Remove the statement nbuf pointing to NULL
during allocation of descriptors as nbuf in rx_desc and next
pointer in dp_rx_desc_list_elem_t share the same address
space and pointing to NULL will not allocate the
rx descriptors.

This change is for supporting monitor mode VAP. All the monitor mode ring
is configured. The related monitor mode ring includes:
-monitor mode buffer ring
-monitor mode destination ring
-monitor mode status ring
-monitor mode link descriptor ring
The packet is not sent to monitor mode ring unless the monitor mode VAP is
configured. This release support Multiple VAP - AP/STA VAP plus Monitor
VAP configuration. The status ring is not used in this release. However,
the ring is tested and the ring is moving and there are TLV's in the ring.

Add support for replenishing the rx buffers using the host to
firmware buffer ring.
This includes adding a flag QCA_HOST2FW_RXBUF_RING:
When QCA_HOST2FW_RXBUF_RING is enabled the host will do the following:
- Allocate the refill buffer ring (HTT_HOST1_TO_FW_RXBUF_RING) and
populate it with
rx buffers
- Send the refill buffer ring configuration to the firmware
- Allocate the rx DMA ring (HTT_RXDMA_HOST_BUF_RING), leave it empty.
- Send the rx DMA ring configuration to the firmware
When QCA_HOST2FW_RXBUF_RING is disabled, the host will do the following:
- Allocate the rx DMA ring (HTT_RXDMA_HOST_BUF_RING), and populate it with
rx buffers
- Send the rx DMA ring configuration to the firmware
