Subject: [dpdk-dev] Aligned RX data.
Date: Tue, 7 Oct 2014 12:40:19 +0300	[thread overview]
Message-ID: <CAKfHP0XoA2jxmR7j0SAT_gWMnS+o6HCTB1-Gj0v4NjL27hQJvg@mail.gmail.com> (raw)

Hi , I'm trying to receive aligned packets from the wire.
Meaning that for all received packets the pkt.data is always aligned to
(512 -H).

Looking at the pmds of ixgbe/vmxnet I see that the pmds call
__rte_mbuf_raw_alloc and set the rx descriptor with a
RTE_MBUF_DATA_DMA_ADDR_DEFAULT
Instead of the more appropriate RTE_MBUF_DATA_DMA_ADDR.

Do I need to modify each pmd I'm using to be able to receive aligned data?
Or have I missed something?

Thanks
