Subject: [dpdk-dev] [PATCH] i40e: fix i40e_reset_tx_queue cmd_type_offset_bsz init
Date: Wed, 01 Oct 2014 15:00:21 -0700	[thread overview]
Message-ID: <20141001220021.19571.38617.stgit@jrharri1-fbsd.ch.intel.com> (raw)

Fix the descriptor initialization loop, so that it initializes
the i40e_tx_desc::cmd_type_offset_bsz for the correct index
into the tx_ring array.

Previously it would use the index once to initialize the txd
local variable, then again when setting cmd_type_offset_bsz.
