Hey Aleksander The device is basic on the Intel 7560 chip, or L860 in fibocom that difference the L850 with PCIe in MBIM protocol. I am not sure there need a PCIe lib or yet, as now I can use lspci found the device, and there is a net port with the drive offered by Intel. And the drive would be open source later time. You add the device L850 of Fibocom in the ModemManager early time, and now the Fibocom want to add the L860 by itself, and I work for Fibocom. So I am going to add a PCIe L860 in the ModemManager. As I planned, I am going to add the L860 in the plugin, then init the device ports(this may need a lib?), then init the modem with AT commd. About the L860 there is a net port, divided in several ports by VLAN id. Here is some description: *The host driver maps each channel exposed by the modem to an interface for application to exercise communication over such channels. For network devices, each IP session (0 to 7) is mapped to INM network interfaces (INM0 to INM7). Thus "/PCIE/IOSM/IPS/0" will be mapped to INM0, "/PCIE/IOSM/IPS/1" will be mapped to "/PCIE/IOSM/IPS/1" and so on. Similarly, "/PCIE/IOSM/CTRL/0" is mapped to RPC device, "/PCIE/IOSM/TRACE/0" to trace, "/PCIE/IOSM/CTRL/0" and "/PCIE/IOSM/CTRL/2" to IAT devices and so on. These are internals to PCIe communication and are transparent to user-space application.*
*The IOSM host driver exposes the interfaces as a VLAN devices (except for flashing device). Following table lists the interfaces exposed by the host driver. Please note that, not every interface is supported by the modem. The host driver allows opening of an interface only if it is supported on the modem side.* Cheers!
