I've changed totemknet reload notify code to be (hopefully) a bit more understandable + improved documentation of net_mtu (hopefully). @chrissie-c Code was already ACKed by Fabio but I would be really grateful if you could review it too and specially review my "english" and potentially convert it to English. |

"This specifies maximum packet length sent by corosync. It's mainly for the UDPU
(and UDP) transport, where it specifies the network maximum transmit size, but
can be used also with the KNET transport, where it defines the maximum length of packets
passed to the knet layer. To specify the network MTU manually for KNET, use the
.B knet_mtu
option.

Switch between manual and automatic MTU discovery. A value of 0 means
automatic, other values set a manual MTU.
In a setup with multiple interfaces, please specify
the lowest MTU of the selected interfaces.
The default value is 0.
totem.knet_mtu is new configuration option which allows setting of automatic or manual knet MTU. Also reload of totem.knet_pmtud_interval is fixed now, so it works when key is deleted (and set back default value). Signed-off-by: Jan Friesse <jfriesse@redhat.com>
