Yes, just a reminder for user, you think I should use " PMD_INIT_LOG( )" instead?
I will change to that.

Yes, I will point out that only pf support in commit log in v4.

ALL config from CLI at first will only keep in DPDK software stored in driver, only after " FLUSH_ON ", it commit all configure to HW.
Because I have to set hardware config at a time, so I have to record all CLI command at first.
" FLUSH_OFF " is just clean all configuration about queue region just now, and restore all to DPDK i40e driver default config when start up.
The following is my test process in CLI:
./x86_64-native-linuxapp-gcc/app/testpmd -c 1ffff -n 4 -- -i --nb-cores=8 --rxq=8 --txq=8 --port-topology=chained
set fwd rxonly
port config all rss all
queue-region set port 0 region_id 0 queue_start_index 2 queue_num 2
queue-region set port 0 region_id 1 queue_start_index 4 queue_num 2
queue-region set pf port 0 region_id 0 flowtype 31
queue-region set pf port 0 region_id 1 flowtype 33
queue-region set pf port 0 region_id 1 flowtype 34
queue-region set port 0 UP 1 region_id 0
queue-region set port 0 UP 3 region_id 1
queue-region flush on port 0
