= What is libmnl? =
libmnl is a minimalistic user-space library oriented to Netlink developers.
There are a lot of common tasks in parsing, validating, constructing of
both the Netlink header and TLVs that are repetitive and easy to get wrong.
This library aims to provide simple helpers that allows you to re-use code
and to avoid re-inventing the wheel. The main features of this library are:
* Small: the shared library requires around 30KB for an x86-based computer.
* Simple: this library avoids complexity and elaborated abstractions that
tend to hide Netlink details.
* Easy to use: the library simplifies the work for Netlink-wise developers.
It provides functions to make socket handling, message building, validating,
parsing and sequence tracking, easier.
* Easy to re-use: you can use the library to build your own abstraction layer
on top of this library.
* Decoupling: the interdependency of the main bricks that compose the library
is reduced, i.e. the library provides many helpers, but the programmer is not
forced to use them.
= Example files =
You can find several example files under examples/ that you can compile by
invoking `make check'.

/**
* \mainpage
*
* libmnl is a minimalistic user-space library oriented to Netlink developers.
* There are a lot of common tasks in parsing, validating, constructing of
* both the Netlink header and TLVs that are repetitive and easy to get wrong.
* This library aims to provide simple helpers that allows you to avoid
* re-inventing the wheel in common Netlink tasks.
*
* \verbatim
"Simplify, simplify" -- Henry David Thoureau. Walden (1854)
\endverbatim
*
* The acronym libmnl stands for LIBrary Minimalistic NetLink.
*
* libmnl homepage is:
* http://www.netfilter.org/projects/libmnl/
*
* \section features Main Features
* - Small: the shared library requires around 30KB for an x86-based computer.
* - Simple: this library avoids complex abstractions that tend to hide Netlink
* details. It avoids elaborated object-oriented infrastructure and complex
* callback-based workflow.
* - Easy to use: the library simplifies the work for Netlink-wise developers.
* It provides functions to make socket handling, message building,
* validating, parsing and sequence tracking, easier.
* - Easy to re-use: you can use this library to build your own abstraction
* layer upon this library, if you want to provide another library that
* hides Netlink details to your users.
* - Decoupling: the interdependency of the main bricks that compose this
* library is reduced, i.e. the library provides many helpers, but the
* programmer is not forced to use them.
*
* \section licensing Licensing terms
* This library is released under the LGPLv2.1 or any later (at your option).
*
* \section Dependencies
* You have to install the Linux kernel headers that you want to use to develop
* your application. Moreover, this library requires that you have some basics
* on Netlink.
*
* \section scm Git Tree
* The current development version of libmnl can be accessed at:
* http://git.netfilter.org/cgi-bin/gitweb.cgi?p=libmnl.git;a=summary
*
* \section using Using libmnl
* You can access several example files under examples/ in the libmnl source
* code tree.

[V1.3.5]
Date: 25/02/2023
enhancement:
1. support efuse SDX sleep
2. support IPQ9574 SFE
fix:
1. fix cannot find the node when dialing. Nodes in the /sys/bus/mhi_q/devices directory named hex
[V1.3.4]
Date: 12/8/2022
enhancement:
1. only allow to enable autosuspend when module is in MHI_EE_AMSS
2. show pcie link speed and width when driver probe
3. check pcie link status by read pcie vid and pid when driver probe,
if pcie link is down, return -EIO
4. support RM520 (1eac:1004)
5. support qmap command packet
fix:
1. fix tx queue is wrong stop when do uplink TPUT
2. fix after QFirehose, module fail to bootup at very small probability
3. mhi uci add mutex lock for concurrent reads/writes
[V1.3.3]
Date: 30/6/2022
enhancement:
1. remove one un-necessary kmalloc when do qfirehose
2. support mhi monitor (like usbmon), usage: cat /sys/kernel/debug/mhi_q/0306_00\:01.00/mhimon
3. set ring size of event 0 to 256 (from 1024), required by x6x
4. support PCIE local network card mhi_swip0 (chan 46/47), default disabled

help
If you say yes to this option, MHI bus support for QTI modem chipsets
will be enabled. QTI PCIe based modems uses MHI as the communication
protocol. MHI control driver is the bus master for such modems. As the
bus master driver, it oversees power management operations such as
suspend, resume, powering on and off the device.

MHI based net device driver for transferring IP traffic
between host and modem. By enabling this driver, clients
can transfer data using standard network interface. Over
the air traffic goes thru mhi netdev interface.
config MHI_UCI

help
MHI based uci driver is for transferring data between host and
modem using standard file operations from user space. Open, read,
write, ioctl, and close operations are supported by this driver.
Please check mhi_uci_match_table for all supported channels that
are exposed to userspace.
config MHI_SATELLITE
tristate "MHI SATELLITE"
depends on MHI_BUS
help
MHI proxy satellite device driver enables NON-HLOS MHI satellite
drivers to communicate with device over PCIe link without host
involvement. Host facilitates propagation of events from device
to NON-HLOS MHI satellite drivers, channel states, and power
management over IPC communication. It helps in HLOS power
savings.

fix:
[V1.2.0.6]
Date: 4/20/2020
enhancement:
1. add stat64, or the rx/tx statics will become to 0 when data > 4G
2. do not use skb_clone, will make QCOM's NSS and SFE 's cpu loading very high
fix:
[V1.2.0.5]
Date: 4/8/2020
enhancement:
1. add attrite link_state, change carrier state accoring link_state
quectel-CM will set link_state to 1 when QMI setup call success.
