Subject: [dpdk-dev] [PATCH v3] net: adjust the header length parse size
Date: Mon,  7 Sep 2020 09:56:50 +0800
Message-ID: <20200907015651.956011-1-haiyue.wang@intel.com> (raw)
In-Reply-To: <20200904054020.77648-1-haiyue.wang@intel.com>

Enlarge the L3 and tunnel header length from 8-bit to 16-bit to handle
the bigger headers. And reorder the fields to avoid creating a structure
hole.

Signed-off-by: Haiyue Wang <haiyue.wang@intel.com>
---
v2: use bit field to avoid creating a structure hole.
v3: use basic type and reorder to avoid structure hole.
