Hi Dear VPP
I wrote a small api client like vpp_api_test that contains
sw_interface_dump api. when i was trying to use this api client i faced a
problem in "stable/1807".
At first i disconnected one of my links and my api client printed below
output:
GigabitEthernet0/9/0 duplex half speed 0
admin: down
link: down
Then i connected the link and got this:
GigabitEthernet0/9/0 duplex full speed 1000
admin: down
link: down
At the end i changed admin status of link and saw below output:
GigabitEthernet0/9/0 duplex bogus speed 0
admin: up
link: up
and show hardware-interface GigabitEthernet0/9/0:
Name Idx Link Hardware
GigabitEthernet0/9/0 2 up GigabitEthernet0/9/0
Ethernet address 08:00:27:94:50:ba
Intel 82540EM (e1000)
carrier up full duplex speed 1000 mtu 9202
flags: admin-up pmd maybe-multiseg tx-offload intel-phdr-cksum
rx queues 1, rx desc 1024, tx queues 1, tx desc 1024
cpu socket 0
based on last results, it seems to be a problem in vl_api_sw_interface_dump.
If I want to describe this problem more, I have to say that 'duplex' and
'speed' api returned values are wrong. however you can see correct values
in "show hardware-interface" cli output.
In addition, GDB output shows that both 'speed' and 'duplex' are zero in
replied mp.
