Subject: [dpdk-dev] [PATCH v2] net/bonding: fix create bonded device test failure
Date: Mon, 28 Jan 2019 07:28:53 +0000	[thread overview]
Message-ID: <1548660533-8710-1-git-send-email-hari.kumarx.vemula@intel.com> (raw)
In-Reply-To: <1546866064-11929-1-git-send-email-hari.kumarx.vemula@intel.com>

Create bonded device test is failing due to improper initialisation in
bonded device configuration. which leads to crash while setting up queues.

The value of nb_rx_desc is checked if it is not in range of rx_desc_lim of
bonded device which fails.
This is due to "rx_desc_lim" is set to 0 as default value of bonded device
during bond_alloc().
Hence nb_rx_desc (1024) is > 0 and test fails.

Fix is to set the default values of rx_desc_lim of bonded device to
appropriate value.

Fixes: 2efb58cbab6e ("bond: new link bonding library")
