In some environment like the current dpdk.org server,
there can be some errors due to symbols in titles,
as it was the case before this commit in DPDK 18.05:
551d148944dc ("doc: remove flow API migration section")
! LaTeX Error: Bad math environment delimiter.
It can be avoided thanks to the Latex command \robustify.
