Subject: [PATCH iproute2-next] ip: promote missed packets to the -s row
missed_packet_errors are much more commonly reported:
linux$ git grep -c '[.>]rx_missed_errors ' -- drivers/ | wc -l
64
linux$ git grep -c '[.>]rx_over_errors ' -- drivers/ | wc -l
37
Plus those drivers are generally more modern than those
using rx_over_errors.
Since recently merged kernel documentation makes this
preference official, let's make ip -s output more informative
and let rx_missed_errors take the place of rx_over_errors.
Before:
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP mode DEFAULT group default qlen 1000
link/ether 00:0a:f7:c1:4d:38 brd ff:ff:ff:ff:ff:ff
RX: bytes packets errors dropped overrun mcast
6.04T 4.67G 0 0 0 67.7M
RX errors: length crc frame fifo missed
0 0 0 0 7
TX: bytes packets errors dropped carrier collsns
3.13T 2.76G 0 0 0 0
TX errors: aborted fifo window heartbeat transns
0 0 0 0 6
After:
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP mode DEFAULT group default qlen 1000
link/ether 00:0a:f7:c1:4d:38 brd ff:ff:ff:ff:ff:ff
RX: bytes packets errors dropped missed mcast
6.04T 4.67G 0 0 7 67.7M
RX errors: length crc frame fifo overrun
0 0 0 0 0
TX: bytes packets errors dropped carrier collsns
3.13T 2.76G 0 0 0 0
TX errors: aborted fifo window heartbeat transns
0 0 0 0 6
