Subject: [dpdk-dev] [PATCH 1/5] ixgbe: avoid compiler error when RTE_IXGBE_INC_VECTOR=y and RTE_LIBRTE_IXGBE_RX_ALLOC_BULK_ALLOC=n
Date: Thu, 26 Jun 2014 14:53:30 +0800
Message-ID: <9db398ae5c25373e4205f5285fc9bd5a63a98e98.1403759017.git.cunming.liang@intel.com> (raw)
In-Reply-To: <cover.1403759017.git.cunming.liang@intel.com>
In-Reply-To: <cover.1403759017.git.cunming.liang@intel.com>

The vpmd RX routine won't be used if RTE_LIBRTE_IXGBE_RX_ALLOW_BULK_ALLOC is not defined or its condition check fail.
The case RTE_LIBRTE_IXGBE_RX_ALLOC_BULK_ALLOC=n and RTE_IXGBE_INC_VECTOR=y may exist
when choose to use standard RX and optimized TX(ixgbe_xmit_pkts_vec/ixgbe_xmit_pkts_simple).
