-Netlink Protocol Library
-
-This library is a clean room re-implementation of libnl 2.0 and
-re-licensed under Apache 2.0. It was developed primarily to support
-wpa_supplicant. However, with additional development can be extended
-to support other netlink applications.
-
-Netlink Protocol Format (RFC3549)
-
-+-----------------+-+-------------------+-+
-|Netlink Message |P| Generic Netlink |P|
-| Header |A| Message Header |A|
-|(struct nlmsghdr)|D|(struct genlmsghdr)|D|

-
-NETLINK OVERVIEW
-
-* Each netlink message consists of a bitstream with a netlink header.
-* After this header a second header *can* be used specific to the netlink
- family in use. This library was tested using the generic netlink
- protocol defined by struct genlmsghdr to support nl80211.
-* After the header(s) netlink attributes can be appended to the message
- which hold can hold basic types such as unsigned integers and strings.
-* Attributes can also be nested. This is accomplished by calling "nla_nest_start"
- which creates an empty attribute with nest attributes as its payload. Then to
- close the nest, "nla_nest_end" is called.
-* All data structures in this implementation are byte-aligned (Currently 4 bytes).
-* Acknowledgements (ACKs) are sent as NLMSG_ERROR netlink message types (0x2) and
- have an error value of 0.
-
-KNOWN ISSUES
-
- GENERAL
- * Not tested for thread safety
-
- Android.mk
- * No dynamic library because of netlink cache not implemented and
- not tested for thread safety
-
- attr.c
- * nla_parse - does not use nla_policy argument
-
- cache.c
- * netlink cache not implemented and only supports one netlink family id
- which is stored in the nl_cache pointer instead of an actual cache
-
- netlink.c
- * nl_recvmsgs - does not support nl_cb_overwrite_recv()
- * nl_recv - sets/unsets asynchronous socket flag
-
