It is observed on sdxpinn target (first multi-core MDM platform)
that WLAN failed to enable IPA pipes with SAP-SAP mode when first
ref-client connects to the SAP. Indeed with QCA_CONFIG_RPS=y and
qdf_ipa_get_lan_rx_napi()=true, wlan_ipa_uc_handle_first_con()
directly returns false if more than 1 SAP is started.
This obviously breaks IPA data path for MDM platform, where even
4 SAP can be supported with IPA offload. And WLAN data path
forwarding replies fully on IPA hardware. This also means there's
no need to configure RPS for MDM, which is a host kernel networking
feature.

which are required for setting up CCE filter rules.
These filters help to determine which packets need

wlan_ipa_uc_loaded_uc_cb is an API that is registered to IPA driver.
Therefore when IPA uC is ready, IPA driver is likely to invoke this CB
into our driver. If it is invoked after a WLAN idle shutdown, ipa_obj
use-after-free will happen because ipa_obj is destroyed as part of
shutdown.
g_ipa_is_ready flag is cleared after ipa_obj is destroyed. Therefore
fix is to add a ipa_cb_is_ready check in wlan_ipa_uc_loaded_uc_cb to
ensure ipa_obj is allocated and not freed.

With IPA TX two pipes support, TX rings for 2G and 5G traffic
are separated. As a result, WLAN needs to let IPA driver
know if the interface registered to IPA is 2G or 5G so that
IPA could differentiate and designate the interface for the
correct IPA TX pipe.
In this change, a new param is_2g_iface is added for the
event interface between protocol and IPA component. And
this new param is applicable only STA_CONNECT and
AP_CONNECT where wlan will register interface details
including is_2g_iface to IPA driver.
For two pipes implementation, is_2g_iface piggy-backs
session_id when passing it to CDP layer. And CDP layer
needs to decode session_id and is_2g_iface.

In DBS scenario(SAP + STA) when all SPA clients disconnect, while STA is
still connected, IPA pipes are disabled on the lithium target. At this
time, its possible that some packets TX from IPA over WLAN are still
pending. If these completions come after IPA pipes are disabled, it can
lead to a NOC error, since the GSI doorbell register for WBM2SW2 ring
may be clock gated (after IPA pipes are disabled).
To avoid this situation, wait for some time before disabling IPA pipes.
IPA pipes are disabled after a timeout, when system suspend call tries
to suspend the bus. A driver unload or a softap tear-down will also
disable the pipes.
