From 4a72909224527386b913bc04b4e535416b7ef5bb Mon Sep 17 00:00:00 2001 From: Dekel Peled Date: Mon, 11 Nov 2019 19:47:35 +0200 Subject: [PATCH] app/testpmd: set maximum LRO packet size This patch implements use of the API for LRO aggregated packet max size. It adds command-line and runtime commands to configure this value, and adds option to show the supported value. Documentation is updated accordingly.
