qcacmn: provide REO2SW1 ring as REO_DST option when IPA is enabled
Currently when IPA is enabled, all RX frames will be routed to IPA
ring REO2SW4 by default, there is no REO2HOST option. once IPA RX/TX
is slow, then likely will give RX back pressure to wlan RXDMA. per
FW feature request, when IPA RX is slow or stuck, route RX frames to
wlan host to mitigate issue, thus provide REO2SW1 ring as REO_DST
option into HWIO_REO_R0_DESTINATION_RING_CTRL_IX_0.
To make sure if without FW dynamic REO_DST ring switching change,
current host change should not give chance that RX frames
route to host when IPA is enabled, select CTRL_IX_0 index 2 to
set REO_DST option, the reason is: if RX hash is enabled, CTRL_IX_2
and CTRL_IX_3 index 16~31 is REO_DST option filled with REO2SW4,
if RX hash is disabled, then CTRL_IX_0 index 1 and 4 filled with
REO2SW4 is REO_DST option configured by
WMI_HOST_PEER_SET_DEFAULT_ROUTING, so CTRL_IX_0 index 2
is only used for FW dynamic ring switching.
