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@debian:~/ 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") Signed-off-by: Nikolay Aleksandrov <nikolay@cumulusnetworks.com> --- v2: simplify print_vlan_stats_attr bridge/vlan.c | 34 +++++++++++++++++++--------------- 1 file changed, 19 insertions(+), 15 deletions(-)
