* rx can pack more than one rx message into a datagram. * rx can make datagrams > MTU. Both these "features" have been called jumbogram. I think the second one is not making things better with todays computers (fast enough CPUs) and network structure (fragmentation and MTU discovery often broken). > Somebody along the way seems > to not fragment these packets, so they just get dropped. That is broken and often there is not much one can do about it. > + rxi_nDgramPackets = 1; I use to set RX_MAX_FRAGS to 1 (rx_globals.h) when I remember it. All the rpms we use internally are patched like that.
