From b3259edcf878bd73d0b23fbdebf183dc90096b78 Mon Sep 17 00:00:00 2001 From: Dekel Peled Date: Wed, 14 Oct 2020 19:35:49 +0300 Subject: [PATCH] app/testpmd: support IPv4 fragments This patch updates testpmd CLI to support fragment_offset field of IPv4 header item. To match on non-fragmented IPv4 packets, need to use pattern: ... ipv4 fragment_offset spec 0 fragment_offset mask 0x3fff ... To match on fragmented IPv4 packets, need to use pattern: ... ipv4 fragment_offset spec 1 fragment_offset last 0x3fff fragment_offset mask 0x3fff ... (Use the full available range 1 to 0x3fff to include all possible values.) To match on any IPv4 packets, fragmented and non-fragmented, the fragment_offset field should not be specified for match.
