mptcpd 0.6

• Mptcpd now supports versions of the Embedded Linux Library (ELL) greater than 0.33.

• Plugins should use the new MPTCPD_PLUGIN_DEFINE() preprocessor macro instead of L_PLUGIN_DEFINE().

• A pointer to the mptcpd path manager object, i.e. struct mptcpd *pm, is now passed to the plugin init and exit functions. This allows plugins to potentially perform mptcpd path manager related operations during initialization and finalization.

• Support for the MPTCP netlink path manager in the upstream Linux kernel is now available. A new set of path management command functions corresponding to those available in the kernel netlink path management API has been added to the <mptcpd/path_manager.h> header. The new functions allow plugins to retrieve IP address information, flush addresses, and modify MPTCP resource limits.

• The mptcpd_pm_add_addr() (formerly mptcpd_pm_send_addr()) and mptcpd_pm_remove_addr() function parameters have been modified in order to support both the upstream and multipath-tcp.org kernels.

• Mptcpd path management command functions declared in <mptcpd/path_manager.h> now return zero on success and -1 or an
  errno on failure instead of a bool.

• A MPTCP address ID manager mptcpd_idm interface was introduced that mptcpd plugins may leverage to map an IP address to a MPTCP address ID, as well as to track used and unused IDs. The interface is defined in the new <mptcpd/id_manager.h> header.

• A new address advertising plugin, addr_adv, has been added. It simply triggers a MPTCP ADD_ADDR when a new IP address is detected by the mptcpd network monitor. Similarly, a MPTCP REMOVE_ADDR is triggered when an IP address is no longer available.

• MPTCP netlink command error message logging was improved to be more descriptive when possible.
