-h Display this text\n\
-H name[/mask],fam Use name (or IP) and family as target of data connection\n\
A mask value will cause randomization of the IP used\n\

Use filename of '?' to get the list of choices\n\
-K loc[,rem] Set the local and/or remote congestion control\n\
algorithm to use on those platforms where it can\n\
be set.\n\
-L name[/mask],fam Use name (or IP) and family as source of data connection\n\
A mask value will cause randomization of the IP used\n\
-m local,remote Set the send size for _STREAM/_MAERTS tests\n\
-M local,remote Set the recv size for _STREAM/_MAERTS tests\n\
-n Use the connected socket for UDP locally\n\
-N Use the connected socket for UDP remotely\n\

Use filename of '?' to get the list of choices\n\
-p min[,max] Set the min/max port numbers for TCP_CRR, TCP_TRR\n\
-P local[,remote] Set the local/remote port for the data socket\n\
-r req,[rsp] Set request/response sizes (TCP_RR, UDP_RR)\n\
-R 0/1 Allow routing of traffic on data connection.\n\
Default: 0 (off) for UDP_STREAM, 1 (on) otherwise\n\
-s send[,recv] Set local socket send/recv buffer sizes\n\
-S send[,recv] Set remote socket send/recv buffer sizes\n\
