REVISIONS

This is v3 of the patch series with addresses serveral problems
raised by Julian Anastasov on the lvs-devel mailing list.

        No other obvious problems in v3 1-12. So,
Acked-by: Julian Anastasov <ja@xxxxxx>

Thanks.


        May be next days I'll test my changes on top of PE v3

I think that could save a bit of porting work later
and perhaps you might notice some more bugs too :-)

        Appending fixes from my tests:

- initialize compat structures to avoid crash in
ip_vs_add_service for pe_name

- fix ip_vs_conn_out_get_proto to properly check the
ip_vs_conn_fill_param_proto result
