In linux kernel since version 5.1 (release Date: 2019-05-05)  
Choose Y or M here to include support for the Qualcomm
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.
