Alexander V. Chernikov 0c325f53f1 Implement flowid calculation for outbound connections to balance
connections over multiple paths.

Multipath routing relies on mbuf flowid data for both transit
 and outbound traffic. Current code fills mbuf flowid from inp_flowid
 for connection-oriented sockets. However, inp_flowid is currently
 not calculated for outbound connections.

This change creates simple hashing functions and starts calculating hashes
 for TCP,UDP/UDP-Lite and raw IP if multipath routes are present in the
 system.

FreeBSD Source:

This is the top level of the FreeBSD source directory. This file was last revised on: FreeBSD

FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.
