Break up the 2MB descriptor bank memory allocations for WBM
idle link ring. Use multiple page allocation and populate the
WBM idle link descriptor ring with physical addresses of each
DMA page allocated in the descriptor bank.
This is to ensure that no requests for contiguous memory
allocations are made that might result in allocation failures.
For MCL set the page size to 4KB and leave it to max_alloc_size
cfg ini param for WIN specific code.

Starting Kernel 4.19 IPA LAN RX supports NAPI polling
mechanism. Netdevs that hook into IPA need to call
netif_receive_skb() or similar to deliver the packet
to network stack instead of using netif_rx_ni().
IPA driver exports ipa_get_lan_rx_napi(void) API for
this purpose. If this API call returns true use
netif_receive_skb() or fallback on legacy api.
Add the changes under a feature flag IPA_LAN_RX_NAPI_SUPPORT
which is enabled under a linux kernel version check for 4.19
and above.

bits occupy same memmory as

As discussed over email this is a temporary WAR
until a long term solution is in place.
Below is the email conversation
This is a temporary change to unblock the present sanity issues
There seems to be a basic issue with nbuf_alloc, with following logic
QDF_NBUF_CB_TX_EXTRA_FRAG_WORDSTR_EFRAG(skb) = 1;
QDF_NBUF_CB_TX_EXTRA_FRAG_WORDSTR_NBUF(skb) = 1;
nbuf_lloc is assuming that the buffer is allocated for TX always
and setting fields in the area of TX portion of union.
If that skb is used for RX can lead to wrong interpretation of the RX
union fields, which is causing present issue.
This got exposed with a recent change that shuffled the fields of
RX union which made the imp fields got manipulated with this TX setting.
We need to resolve this basic issue with wider consent and validations,
while this fix unblocks the basic sanity issues.

The scheduler watchdog timer handler currently either prints error or
prints error and panics based on CONFIG_SLUB_DEBUG_ON.
Considering the panic through QDF_DEBUG_PANIC is configurable and is
disabled on relevant builds, we can just have one version of the
function and depend on QDF macro for panic and dependency on
CONFIG_SLUB_DEBUG_ON is redundant
Change the default log levels from none to fatal for scheduler.

Currently, QDF_MAX_CONCURRENCY_PERSONA allows a maximum of 4
MAC addresses to be assigned to different interfaces. NAN
discovery interface is a new interface and it needs a MAC address
to be assigned. QDF_MAX_CONCURRENCY_PERSONA needs to be increased
to 5 to provide the same.
WLAN_MAX_VDEVS defined in Kbuild already takes care of the
maximum no.of vdevs(6) supported. QDF_MAX_CONCURRENCY_PERSONA can
be made dependent of WLAN_MAX_VDEVS which caters the same purpose.
Define QDF_MAX_CONCURRENCY_PERSONA accordingly.

Depending on the requirement, a bigger size or a smaller size for
the frequency variable can be chosen. The advantages of each size
are described below:
Advantage of a bigger size:
When two technologies (e.g. 802.11AX and 802.11AD) are controlled
by the same driver software, the frequency range may be very large
and a bigger size (e.g. 32bit integer) is more appropriate.
Advantage of a smaller size:
When the frequency range is not very large, a smaller size
(e.g. 16bit integer) can be used. It saves a large amount of space
especially when many large arrays containing elements of this
type/size are defined in the driver.

In SLUB disabled builds, the qdf_mem_malloc calls the
qdf_mem_malloc_fl function which doesn't
validate if the size provided is 0 and returns the value
ZERO_SIZE_PTR(((void *)16)) for the pointer. When this pointer
is dereferenced, it causes invalid address dereference.
Validate if the size parameter provided to qdf_mem_malloc is
0 or greater than QDF_MEM_MAX_MALLOC. Return failure if the
validation fails.
