From 9a5c09211b3a6de69efa88429409fa5a1be5e9e3 Mon Sep 17 00:00:00 2001 From: Thomas Monjalon Date: Wed, 14 Apr 2021 22:15:43 +0200 Subject: [PATCH] doc: announce extension of crypto data-unit length The struct member dataunit_len is introduced in DPDK 21.05. It is limited to 16 bits to fit a padding hole in 32-bit build. This means the maximum data-unit length is 64 KB. Some use cases may benefit of a bigger size as the proposed 32 bits.
