Subject: [PATCH iproute2] bridge: vlan: fix standard stats output
Each of the commits below broke the vlan stats output in a different
way:
- 45fca4ed9412 ("bridge: fix vlan show stats formatting")
Added a second print of an interface name (e.g. eth4eth4)
- c7c1a1ef51ae ("bridge: colorize output and use JSON print library")
Broke normal vlan stats output by not printing a new line after them
Also printed interfaces without any vlans when printing stats
This fix is not pretty but it brings back the previous behaviour.
Before this fix:
$ bridge -s vlan show
port vlan id
br0br0 1 PVID Egress Untagged
RX: 0 bytes 0 packets
TX: 0 bytes 0 packets 4
RX: 0 bytes 0 packets
TX: 0 bytes 0 packetseth4eth4 4
RX: 0 bytes 0 packets
TX: 0 bytes 0 packetsroot@...ian:~/
After this fix:
$ bridge -s vlan show
port vlan id
br0 1 PVID Egress Untagged
RX: 0 bytes 0 packets
TX: 0 bytes 0 packets
4
RX: 0 bytes 0 packets
TX: 0 bytes 0 packets
eth4 4
RX: 0 bytes 0 packets
TX: 0 bytes 0 packets
Fixes: 45fca4ed9412 ("bridge: fix vlan show stats formatting")
Fixes: c7c1a1ef51ae ("bridge: colorize output and use JSON print library")
