When possible, network drivers are now started automatically. That means that netconf(8)'s network driver selection has become obsolete. This patch changes netconf(8) to allow the user to specify a network configuration (currently one of DHCP IPv4+IPv6, DHCP IPv4-only, manual IPv4-only) for any hardware network interfaces that are currently present. Selection of network drivers that require manual configuration first (mainly old ISA cards) is still supported, but now as a special case. Change-Id: I6208fc75192eb7f0b061862aaf7507f71a620da4

# netconf 0.2 - Configure network

|
|
# Changes:
|
|
# v0.2: rewrite for NetBSD network infrastructure
|
|
# - the primary choice is now for an interface, not a network card;
|
|
# - manual driver configuration is now an exception;
|
|
# - the menu transition system is slightly more solid;
|
|
# - all non-interactive functionality has been removed.
