This change creates an array of port maps indexed by numa domain for lacp port selection. If we have lacp interfaces in more than one domain, then we select the egress port by indexing into the numa port maps and picking a port on the appropriate numa domain. This is behavior is controlled by the new ifconfig use_numa flag and net.link.lagg.use_numa sysctl/tunable (both modeled after the existing use_flowid), which default to enabled.

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.
