On low memory system, skb allocation failures are observed in
dp_tx_ipa_uc_attach during driver loading phase. Per kernel
memory team analysis, failures are caused by large amount of
atomic allocations. Currently when allocating IPA TX skbs,
srng spinlock is first grabbed and then skb buffers are being
requested, which makes skb allocation happen in atomic context.
Fix is to make skb allocations with srng unlocked since it is
safe for race conditions during driver loading time. This ensures
skb allocations in process context.

When the status is FLOW_POOL_ACTIVE_PAUSED, all queues are expected to
be paused. Still some on the fly packet can make it to the driver. In
such a case, the function dp_tx_desc_alloc takes a default action of
WLAN_WAKE_NON_PRIORITY_QUEUE. This is incorrect, since it will wake all
non priority queues, when they should be paused.
Make default action as WLAN_NETIF_ACTION_TYPE_NONE. If this is the
action to be taken, donot call the pause_cb from dp_tx_desc_alloc.
Rate limit log levels in case dp_tx_desc_alloc fails.

In some cases, the msdu_len as retrieved fromm msdu_start TLV is
greater than RX_BUFFER_SIZE. In such cases, when qdf_nbuf_set_pktlen
is called, it will expand the skb to accommodate the bigger packet.
This makes the rx_tlv_hdr var invalid, since it continues to point to
the older skb->data. Access of this rx_tlv_hdr will cause exception.
Drop the packet if msdu_len > RX_BUFFER_SIZE. This is not expected while
reaping WBM RX Release ring.

Currently rx reorder queue setup command is sent from soft irq
context. There exists race condition between resume command sent
from worker thread context and this command sent from soft irq
context. In parallel execution on different cpu cores if the wmi
suspend flag is not sent to false as part of resume command at the
time of sending the rx reorder queue setup wmi command, the command
will not be sent. So serialize the rx reorder queue setup command
by posting to scheduler thread.

Support WLAN IPA WDI 3.0 with SMMU-S1 enabled. Key design
considerations are captured below.
- ring base addresses are passed as struct sg_table and IPA
driver will do the IOVA mapping to IPA domain.
- ring doorbell addresses are passed as physical address and
IPA driver will do the IOVA mapping to IPA domain.
- TX/RX buffers need to be mapped to IPA domain by WLAN driver
via ipa_wdi_create|release_smmu_mapping API.
- IPA doorbell addresses returned from ipa_wdi_conn_pipes are
DDR addresses and WLAN driver needs to do the IOVA mapping
to WLAN domain.
