network: interface ioctls for FreeBSD - #8
Merged

Conversation
FreeBSD's netlink creates a cloned interface only under its cloner name (bridge0, epair0a), cannot rename one, cannot move one into a jail and does not manage bridge members. Those are ioctls, the same ones ifconfig(8) uses. Add a network::freebsd module wrapping SIOCIFCREATE2, SIOCIFDESTROY, SIOCSIFNAME, SIOCSIFVNET and SIOCSDRVSPEC/SIOCGDRVSPEC with BRDGADD and BRDGGIFS, plus if_indextoname. The ioctl numbers are computed from the ioccom encoding and unit-tested against the values printed from the system headers, as is the size of struct ifbreq. Nothing calls it yet; the netlink and bridge changes that do follow. Signed-off-by: Michael Johnson <buhnux@gmail.com>
