Subject: [dpdk-dev] [PATCH 1/2] lib/librte_ethdev: add in default value of rte_eth_dev_info
Date: Mon, 27 May 2019 14:05:28 +0530 [thread overview]
Message-ID: <1558946129-5816-2-git-send-email-skori@marvell.com> (raw)
In-Reply-To: <1558946129-5816-1-git-send-email-skori@marvell.com>
rte_eth_dev_info structure exposes, nb_seg_max & nb_mtu_seg_max
to provide maximum number of supported segments for a given platform.
Defining UINT16_MAX as default value of above mentioned variables to
expose support of infinite/maximum segments.
Based on above values, application can decide best size for buffers
while creating mbuf pool.
