Hi,

For the current code about flow query <portid> <ruleid> count 
It is printf("%s:\n"
	" hits_set: %u\n"
	" bytes_set: %u\n"
	" hits: %" PRIu64 "\n"
	" bytes: %" PRIu64 "\n",
	name,
	query.count.hits_set,
	query.count.bytes_set,
	query.count.hits,
	query.count.bytes);
and it will display the info like:
COUNT:
 hits_set: xxx
 bytes_set : xxx
 hits: xxx
 bytes: xxx

so for the code style and info style like it, I add some space in the log to make sure the log like
RSS:
 Queues: none|0|1|...
 Function: default| Toeplitz| simple_xor| symmetric_toeplitz| Unknown function
 Types:
  none
  Ipv4-tcp
  Ipv4-udp
  
For the reason the types may be many types, and if the line in testpmd log is too long.
It may cause error, so the types info is displayed per line and with one more space before.

Two lines needed? And why don't you add the space in the end of this printf?
