Subject: Added support for a BROPTS variable to set bridge specific settings.

Before, it was not possible to set bridge specific options when creating
a bridge.  This option adds the ability to set options via a BROPTS
variable, which takes a pipe (|) delimited set of options as documented
in the ip-link(8) man page (search for "BRIDGE Type Support").
