Currently dp_main.c generates warnings when compiled with the GCC
-Wmissing-prototypes switch because it does not include a header file
which exports a prototype for dp_soc_attach_wifi3(). Currently the "dp
soc attach" APIs are defined in a strange manner, and there is not a
prototype which dp_main.c can include. So as a WAR define the
prototype internal to dp_main.c itself.
Of course the whole point of -Wmissing-prototypes is to prevent
mismatches between callers of an interface and the implementation of
an interface, and this WAR explicitly bypasses that protection. This
WAR should be superceded in the future by a proper registration
mechanism where the architecture-specific DP implementation attaches
to the Converged Data Path (CDP).

We want to enable the compiler's -Wmissing-prototypes switch, but
there is existing code in dp_main.c that is generating warnings. Fix
these warnings by making all functions static that are only referenced
internally to dp_main.c.

The MC BC packets cause a NULL REO queue descriptor exception,
and hence are directed to the ring that is configured to receive
this exception from REO. As of now, this error is directed to
WBM release ring. Add handling to pass these packets to stack
instead of dropping them, when received on the WBM release ring.
Note that, the final fix may be route these to REO exception ring
from which the driver may need to pass them to stack.

Currently, suspend/resume fails because data path suspend/resume ops
are not set. Add dummy ops for data path bus suspend and bus resume,
that simply return success. Actual implementations will follow.

Seperate the dp peer object allocation from setting the peer's
default routing and default rx tid queues.
This change is to address a race condition where the HTT peer map
message arrives before the peer object is created.

Enable timer based polling of the UMAC rings for Tx completion
and Rx. (Interrupts are not yet ready on UMAC rings).
(DP_INTR_POLL_BASED is defined through Kbuild)
Also define the polling timer as 100 ms.

Add a generic framework (wlan_cfg) for all configuration parameters
(eg.number of tx/rx rings) used by DP. Define all the parameters
as macro constants. We will later enhance wlan_cfg framework to
read these parameters from device tree file or ini file and populate
in DP config structures.

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
