NETLINK is going to replace rtsock and a number of other ioctl/sysctl interfaces. In-base utilies such as route(8), netstat(8) and soon ifconfig(8) are being converted to use netlink sockets as a transport between kernel and userland. In the current configuration, it still possible have the kernel without NETLINK (`nooptions NETLINK`) and use the aforementioned utilies by buidling the world with `WITHOUT_NETLINK` src.conf knob. However, this approach does not cover the cases when person unintentionally builds a custom kernel without netlink and tries to use the standard userland. This change adds `option NETLINK` to the default options for each architecture, fixing the custom kernel issue. For arm, this change uses `std.armv6` and `std.armv7` (netlink already in) instead of DEFAULTS. Reviewed By: imp Differential Revision: https://reviews.freebsd.org/D39339 |

FreeBSD Kernel Source:
This directory contains the source files and build glue that make up the FreeBSD kernel and its modules, including both original and contributed software.
Kernel configuration files are located in the conf/
subdirectory of each
architecture. GENERIC
is the configuration used in release builds. NOTES
contains documentation of all possible entries. LINT
is a compile-only
configuration used to maximize build coverage and detect regressions.
