ipvs: extend connection flags to 32 bits
- the sync protocol supports 16 bits only, so bits 0..15 should be used only for flags that should go to backup server, bits 16 and above should be allocated for flags not sent to backup. - use IP_VS_CONN_F_DEST_MASK as mask of connection flags in destination that can be changed by user space - allow IP_VS_CONN_F_ONE_PACKET to be set in destination Signed-off-by: Julian Anastasov <ja@ssi.bg> Signed-off-by: Patrick McHardy <kaber@trash.net>
