=head1 search_by_mac( \%cond, \%attrs? )

 my $set = $rs->search_by_mac({mac => '00:11:22:33:44:55', active => 1});

Like C<search()>, this returns a ResultSet of matching rows from the Node
table.

=over 4

=item *

The C<cond> parameter must be a hashref containing a key C<mac> with
the value to search for.

=item *

Results are ordered by time last seen.

=item *

Additional columns C<time_first_stamp> and C<time_last_stamp> provide
preformatted timestamps of the C<time_first> and C<time_last> fields.

=item *

A JOIN is performed on the Device table and the Device C<dns> column
prefetched.

=back

To limit results only to active nodes, set C<< {active => 1} >> in C<cond>.
