hi,
i have two questiones to consult.
software version: openvswitch-2.6.90.13454.gita9ba22b7 , 3.10.0-327.36.3.el7
1. why logical_switch_port's rate and burst is set on physical device, rather
than port's tap device? does this policy work? .why ovn does not choose to
setup ovs's db， but to call netdev's api?
options of port_binding is 'qdisc_queue_id="2", qos_burst="25000",
qos_max_rate="55000"'.
#tc class show dev eth0
class htb 1:fffe root rate 100000Kbit ceil 100000Kbit burst 1500b cburst 1500b
class htb 1:2 parent 1:fffe prio 0 rate 12000bit ceil 52000bit burst 2749b
cburst 2749b
class htb 1:3 parent 1:fffe prio 0 rate 12000bit ceil 55000bit burst 3124b
cburst 3124b
2. how the following flows are handled in kernel space or in user space(where
is the code)? it seems that ovs translates queue_id into sob_priority. if i
miss something.
please tell the process flow
cookie=0x0, duration=979234.497s, table=16, n_packets=0, n_bytes=0,
idle_age=65534, hard_age=21295,
priority=50,reg14=0x2,metadata=0x1,dl_src=02:ac:10:ff:01:94
actions=set_queue:2,resubmit(,17)
