Subject: [PATCH iproute2 v3 0/3] bridge: fixes regarding the colorized output

v3:
 - Remove the unnecessary is_json_context() condition checks from patch 2/3
   as the print_string() call is used with the argument PRINT_FP.

v2:
 - Replace the 2 newly introduced fprintf() func calls with print_string()
   to address Stephen's suggestion.

For the bridge cmd, the "colorize output" cmd line option's usage and the
corresponding output does not seem to be consistent with the usage and the
output of the "ip" cmds.

Example 1: As per the "colorize output" cmd line option documented in the
man pages man/man8/ip.8 & man/man8/bridge.8, using "-c" with "ip" or the
"bridge" should colorize the output. But this is working only with the "ip"
cmd and for the "bridge" cmd, the option "-col" / "-colo" / "-color" needs
to be used instead of just "-c".

Example 2: After fixing the inconsistency mentioned in Example 1,
- Running the cmd "$ ip -c neigh", will give the following output where the
  "172.16.12.250", "bridge0" & "04:d9:f5:c1:0c:74" fields are highlighted
  and not the fixed keywords "dev" & "lladdr".

  172.16.12.250 dev bridge0 lladdr 04:d9:f5:c1:0c:74 REACHABLE

- But running the cmd "$ bridge -c fdb", will give the following output
  where "00:00:00:00:00:00", "dev", "vxlan100", "dst" & "2001:db8:2::1" are
  highlighted, even though "dev" & "dst" keywords are static.

  00:00:00:00:00:00 dev vxlan100 dst 2001:db8:2::1 self permanent

Also fix a typo in man/man8/bridge.8 to change "-c[lor]" into "-c[olor]".

Gokul Sivakumar (3):
  bridge: reorder cmd line arg parsing to let "-c" detected as "color"
    option
  bridge: fdb: don't colorize the "dev" & "dst" keywords in "bridge -c
    fdb"
  man: bridge: fix the typo to change "-c[lor]" into "-c[olor]" in man
    page
