Hi,

DPDK 19.11 LTS is EOL. Please see: https://core.dpdk.org/roadmap/#stable

For reference, the named commit does not exist in dpdk main. It looks 
like the patch is a rebase of:

     app/testpmd: fix build with clang 15 in flow code

     This variable is not used and has been copy/pasted in a lot of other
     code.

     Fixes: 938a184a1870 ("app/testpmd: implement basic support for flow 
API")
