* Qualcomm Technologies, Inc. RmNet IPA driver module



This module enables embedded data calls using IPA v3 HW.



Required properties:

- compatible:		Must be "qcom,rmnet-ipa3"



Optional:

- qcom,rmnet-ipa-ssr: determine if modem SSR is supported

- qcom,ipa-loaduC: indicate that ipa uC should be loaded



Example:

	qcom,rmnet-ipa3 {

		compatible = "qcom,rmnet-ipa3";

	}
