When peer_unmap_timer_handler runs for multiple peers, same work
is INITed for multiple peers as this work is not per peer based.
This will update the work param i.e. peer gets updated each time,
which leads in deletion of wrong peer.
Remove the work INIT and scheduling of "peer_unmap_timer_work_function"
as cds_trigger_recover() has already taken care of atomic context.

As for Rome, currently it usually just only support two
IPA interfaces offload, if use the default value 3, which
will cause the IPA pipe setup failure issue. So export
the max IPA interface numbers, and it's better to set
the appropriate value from build file according to
different requirement for different chipset and platform.
Meanwhile, it support SMMU on the sa415 platform, so
enable SMMU for it.

In the htt_ipa_uc_get_resource, rx2_rdy_ring is from
pdev->ipa_uc_rx_rsc.rx2_ind_ring, rx2_proc_done_idx is
from pdev->ipa_uc_rx_rsc.rx2_ipa_prc_done_idx, but
rx2_ind_ring & rx2_ipa_prc_done_idx are not used for
WDI 1.0, just only used for WDI 2.0, which initialized in
the htt_rx_ipa_uc_alloc_wdi2_rsc. So as for Rome that use
WDI 1.0, these two variables are not initialized and thus
they are NULL pointers. Therefore this change can fix NULL
pointer deference for WDI 1.0 when CONFIG_IPA_WDI_UNIFIED_API
is defined and meanwhile QCA_WIFI_3_0 used to distinguish WDI 2.0
and WDI 1.0 IPA RX params.

In case of TSO, same buffer results in multiple tx_desc after
segmentations. To avoid multiple free of skb ref_cnt is used.
Currently ref_cnt is incremented twice for 1st segment and
not incremented for last segment and in case of failure from
ce_send_fast, ref_cnt is decremented twice.
Above logic don't work in case when TSO packet with segment
count is 1 and ce_send_fast failure is observed.
So, Change logic to increment ref_cnt only once for 1st segment
and avoid reducing ref_cnt twice in case of ce_send_fast failure.

This change adds support for driver supported TCP
delayed ack to increase TCP RX performance in
third-party platform which does't support kernel
TCP delayed ack feature.
TCP delayed ack is dependent on count and timer
values. Whatever is achieved first will trigger
sending TCP ack.
This feature can be controlled through ini values.
gDriverDelAckTimerValue - timer value in ms
gDriverDelAckPktCount - delayed ack count
gDriverDelAckEnable - enable/disable feature

Add stop_th and start_th for QCA_LL_TX_FLOW_CONTROL_V2 disabled
platform, which is pdev based tx_desc pool. Change pdev tx_desc pool
size from 1056 to 900, default stop_th is 15% start_th is 25%, this
setting is exactly same as QCA_LL_TX_FLOW_CONTROL_V2. Pause netif tx
queues for all vdevs when stop_th reached instead of dropping frames.
Reduce pdev pool size could significantly reduce firmware wmm drop. Both
of host and firmware frame dropps lead to bad TCP throughput.
