Subject: [dpdk-dev] [PATCH v2] librte_mbuf: modify port initialization value
Date: Tue,  5 Sep 2017 13:13:19 +0800	[thread overview]
Message-ID: <20170905051319.11223-1-zhiyong.yang@intel.com> (raw)
In-Reply-To: <20170904065532.13055-1-zhiyong.yang@intel.com>

In order to support more than 256 virtual ports, the field "port"
in rte_mbuf has been increased to 16 bits. The initialization/reset
value of the field "port" should be changed from 0xff to 0xffff
accordingly.

Signed-off-by: Zhiyong Yang <zhiyong.yang@intel.com>

Changes in V2:
Introduce MBUF_INVALID_PORT as a constant.
