+         IP Accelerator (IPA), a hardware block present in some
+         Qualcomm SoCs.  The IPA is a programmable protocol processor
+         that is capable of generic hardware handling of IP packets,
+         including routing, filtering, and NAT.  Currently the IPA
+         driver supports only basic transport of network traffic
+         between the AP and modem, on the Qualcomm SDM845 SoC.
+
+         Note that if selected, the selection type must match that
+         of QCOM_Q6V5_COMMON (Y or M).
+
+         If unsure, say N.
