[PATCH iproute2] iplink_can: print_usage: typo fix, add missing spaces

From: Vincent Mailhol
Date: Sat Feb 12 2022 - 08:28:18 EST


The can help menu misses three spaces for the TDCV, TDCO and TDCF
parameters, making the closing curly bracket unaligned.

For reference, before this patch:

| $ ip link help can
| Usage: ip link set DEVICE type can
| [ bitrate BITRATE [ sample-point SAMPLE-POINT] ] |
| [ tq TQ prop-seg PROP_SEG phase-seg1 PHASE-SEG1
| phase-seg2 PHASE-SEG2 [ sjw SJW ] ]
|
| [ dbitrate BITRATE [ dsample-point SAMPLE-POINT] ] |
| [ dtq TQ dprop-seg PROP_SEG dphase-seg1 PHASE-SEG1
| dphase-seg2 PHASE-SEG2 [ dsjw SJW ] ]
| [ tdcv TDCV tdco TDCO tdcf TDCF ]
|
| [ loopback { on | off } ]
| [ listen-only { on | off } ]
| [ triple-sampling { on | off } ]
| [ one-shot { on | off } ]
| [ berr-reporting { on | off } ]
| [ fd { on | off } ]
| [ fd-non-iso { on | off } ]
| [ presume-ack { on | off } ]
| [ cc-len8-dlc { on | off } ]
| [ tdc-mode { auto | manual | off } ]
|
| [ restart-ms TIME-MS ]
| [ restart ]
|
| [ termination { 0..65535 } ]
|
| Where: BITRATE := { NUMBER in bps }
| SAMPLE-POINT := { 0.000..0.999 }
| TQ := { NUMBER in ns }
| PROP-SEG := { NUMBER in tq }
| PHASE-SEG1 := { NUMBER in tq }
| PHASE-SEG2 := { NUMBER in tq }
| SJW := { NUMBER in tq }
| TDCV := { NUMBER in tc}
| TDCO := { NUMBER in tc}
| TDCF := { NUMBER in tc}
| RESTART-MS := { 0 | NUMBER in ms }

... and after this patch:

| [ tq TQ prop-seg PROP_SEG phase-seg1 PHASE-SEG1

|
| [ dbitrate BITRATE [ dsample-point SAMPLE-POINT] ] |
| [ dtq TQ dprop-seg PROP_SEG dphase-seg1 PHASE-SEG1
| dphase-seg2 PHASE-SEG2 [ dsjw SJW ] ]
| [ tdcv TDCV tdco TDCO tdcf TDCF ]
|
| [ loopback { on | off } ]
| [ listen-only { on | off } ]
| [ triple-sampling { on | off } ]
| [ one-shot { on | off } ]
| [ berr-reporting { on | off } ]
| [ fd { on | off } ]
| [ fd-non-iso { on | off } ]
| [ presume-ack { on | off } ]
| [ cc-len8-dlc { on | off } ]
| [ tdc-mode { auto | manual | off } ]
|
| [ restart-ms TIME-MS ]
| [ restart ]
|
| [ termination { 0..65535 } ]
|
| Where: BITRATE := { NUMBER in bps }
| SAMPLE-POINT := { 0.000..0.999 }
| TQ := { NUMBER in ns }

| PHASE-SEG2 := { NUMBER in tq }
| SJW := { NUMBER in tq }
| TDCV := { NUMBER in tc }
| TDCO := { NUMBER in tc }
| TDCF := { NUMBER in tc }
| RESTART-MS := { 0 | NUMBER in ms }
