Subject: [dpdk-dev] [PATCH v2] doc: relocate i40e known issues
Date: Tue, 28 Mar 2017 10:28:56 +0800 [thread overview]
Message-ID: <1490668136-46758-1-git-send-email-qiming.yang@intel.com> (raw)
In-Reply-To: <1490330480-26531-1-git-send-email-qiming.yang@intel.com>
This patch moved i40e related known issues from doc/guides/rel_notes/
known_issues.rst to doc/guides/nics/i40e.rst, makes us easy
to track the issue about i40e.

Limitations or Known issues
---------------------------
+Cannot set link speed on Intel® 40G Ethernet controller
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+On Intel® 40G Ethernet Controller you cannot set the link to specific
+speed. The link speed cannot be changed forcibly, though it can be
+configured by application.
+
+I40e VF may not receive packets in the promiscuous mode
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Promiscuous mode is not supported by the DPDK i40e VF driver when using
+the i40e Linux kernel driver as host driver. The i40e VF does not receive
+packets when the destination MAC address is unknown. Use a explicit
+destination MAC address that matches the VF can avoid this problem.
+
+uio pci generic module bind failed in X710/XL710/XXV710
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+When use ``--bind=uio_pci_generic``, the ``uio_pci_generic`` module probes
+device and check the Interrupt Status bit. Since it is not supported by
+X710/XL710/XXV710, it return a *failed* value. The statement that these
+products don’t support INTx masking, is indicated in the related `linux kernel
+commit <https://git.kernel.org/cgit/linux/kernel/git/stable/linux-stable.git/
+commit/drivers/pci/quirks.c?id=8bcf4525c5d43306c5fd07e132bc8650e3491aec>`_.
+Do not bind the ``uio_pci_generic`` module in X710/XL710/XXV710 NICs.

-uio pci generic module bind failed in X710/XL710/XXV710
--------------------------------------------------------
-
-**Description**:
- The ``uio_pci_generic`` module is not supported by XL710, since the errata of XL710
- states that the Interrupt Status bit is not implemented. The errata is the item #71
- from the `xl710 controller spec
- <http://www.intel.com/content/www/us/en/embedded/products/networking/xl710-10-40-controller-spec-update.html>`_.
- The hw limitation is the same as other X710/XXV710 NICs.

-**Implication**:
- When use ``--bind=uio_pci_generic``, the ``uio_pci_generic`` module probes device and check the Interrupt
- Status bit. Since it is not supported by X710/XL710/XXV710, it return a *failed* value. The statement
- that these products don’t support INTx masking, is indicated in the related `linux kernel commit
