=head3 clearcache
Workaround: Clear the IP address cache in case that the long running process
(discovery/install monitor) could work as normal when the node's IP address
is changed.
Globals:
cache: %::hostiphash
Error:
none
Example:
xCAT::NetworkUtils->clearcache();
=cut
#-------------------------------------------------------------------------------
sub clearcache
{
undef %::hostiphash;
}
#-------------------------------------------------------------------------------
=head3 linklocaladdr
Only for IPv6.
Takes a mac address, calculate the IPv6 link local address
