[dpdk-dev] [PATCH 1/2] examples/l3fwd-vf: remove old Rx/Tx configuration defines

Mon Jun 3 12:06:18 CEST 2019


The RX and TX Prefetch, Host, and Write-back threshold values are
defined but not used anywhere. They are leftovers from a previous
patch.

Fixes: 81f7ecd9 ("examples: use factorized default Rx/Tx configuration")
