* [dpdk-dev] [PATCH] examples/l2fwd-event: changes to use event vector
@ 2021-09-04  7:46 Shijith Thotton
  2021-09-27  6:21 ` [dpdk-dev] [PATCH v2] " Shijith Thotton

From: Shijith Thotton @ 2021-09-04  7:46 UTC (permalink / raw)
  To: dev
  Cc: Shijith Thotton, jerinj, ndabilpuram, pbhagavatula, schalla,
	Sunil Kumar Kori

Added changes to receive packets as event vector. By default this is
disabled and can be enabled using the option --enable-vector. Vector
size and timeout to form the vector can be configured using options
--vector-size and --vector-tmo-ns.

Example:
	dpdk-l2fwd-event -l 0-3 -n 4 -- -p 0x03 --mode=eventdev \
	--eventq-sched=ordered --enable-vector --vector-size 16
