The commands in the comment never worked verbatim.

$  sed -rn 's;.*(ETHTOOL_LINK_MODE_)([0-9]+)([0-9a-zA-Z_]*).*= *([0-9]*).*;'\
           '[\4] \2 \1\2\3;p' /usr/include/linux/ethtool.h |
   awk '/_Half_/{$2=$2+1}1' |
   awk '{printf "\t%5s = %7s, /\* %s *\/\n", $1, $2, $3}'

Fixing the comment would be:
