commit 8c6321466df9a452ac58e09d32edd6c5b4ea0d17

    [IPROUTE]: Fix up "ip link" help text
    
    Add help for "ip link add". Also fix up the "ip link set" help text:
    
    - the flags are not mutually exclusive as suggested by the current text,
      up/down states and on/off are mutually exclusive.
    
    - txqueuelen, name etc. have nothing to do with the flags and on/off states
      at all and are certainly not mutually exclusive, fix formatting and make
      it conform the other helptexts better.
