+ @param sw_if_index - The interface the RA prefix information is for
+ @param address[] - The prefix to advertise
+ @param address_length - the prefix length
+ @param use_default - Revert to default settings
+ @param no_advertise - Do not advertise this prefix
+ @param off_link - The prefix is off link (it is not configured on the interface)
+ Configures the L-flag, When set, indicates that this
+ prefix can be used for on-link determination.
+ @param no_autoconfig - Setting for the A-flag. When
+ set indicates that this prefix can be used for
+ stateless address configuration.
+ @param no_onlink - The prefix is not on link. Make sure this is consistent
+ with the off_link parameter else YMMV
+ @param is_no - add/delete
+ @param val_lifetime - The length of time in
+ seconds (relative to the time the packet is sent)
+ that the prefix is valid for the purpose of on-link
+ determination. A value of all one bits
+ (0xffffffff) represents infinity
+ @param pref_lifetime - The length of time in
+ seconds (relative to the time the packet is sent)
+ that addresses generated from the prefix via
+ stateless address autoconfiguration remain
+ preferred [ADDRCONF]. A value of all one bits
+ (0xffffffff) represents infinity.
