/** * DOC: The IP Accelerator * * This driver supports the Qualcomm IP Accelerator (IPA), which is a * networking component found in many Qualcomm SoCs. The IPA is connected * to the application processor (AP), but is also connected (and partially * controlled by) other "execution environments" (EEs), such as a modem. * * The IPA is the conduit between the AP and the modem that carries network * traffic. This driver presents a network interface representing the * connection of the modem to external (e.g. LTE) networks. * * The IPA provides protocol checksum calculation, offloading this work * from the AP. The IPA offers additional functionality, including routing, * filtering, and NAT support, but that more advanced functionality is not * currently supported. Despite that, some resources--including routing * tables and filter tables--are defined in this driver because they must * be initialized even when the advanced hardware features are not used. * * There are two distinct layers that implement the IPA hardware, and this * is reflected in the organization of the driver. The generic software * interface (GSI) is an integral component of the IPA, providing a * well-defined communication layer between the AP subsystem and the IPA * core. The GSI implements a set of "channels" used for communication * between the AP and the IPA. * * The IPA layer uses GSI channels to implement its "endpoints". And while * a GSI channel carries data between the AP and the IPA, a pair of IPA * endpoints is used to carry traffic between two EEs. Specifically, the main * modem network interface is implemented by two pairs of endpoints: a TX * endpoint on the AP coupled with an RX endpoint on the modem; and another * RX endpoint on the AP receiving data from a TX endpoint on the modem.
