[dpdk-dev] [PATCH v3 0/3]: bug fixes in the ixgbe PF PMD Rx flow

[Vlad Zolotarov]

This series contains some bug fixes that were found during my work on the ixgbe LRO
patches. Sending this series separately on Thomas request so that it may be integrated
into the 2.0 release.

New in v3:
   - Adjusted to the new structs naming in the master.
   - Fixed rx_bulk_alloc_allowed and rx_vec_allowed initialization:
      - Don't set them to FALSE in rte_eth_dev_stop() flow - the following
        rte_eth_dev_start() will need them.
      - Reset them to TRUE in rte_eth_dev_configure() and not in a probe() flow.
        This will ensure the proper behaviour if port is re-configured.
   - Rename:
      - ixgbe_rx_vec_condition_check() -> ixgbe_rx_vec_dev_conf_condition_check()
      - set_rx_function() -> ixgbe_set_rx_function()
   - Clean up the logic in ixgbe_set_rx_function().
   - Define stubs with __attribute__((weak)) instead of using #ifdef's.
   - Styling: beautify ixgbe_rxtx.h a bit.

New in v2:
   - Fixed a compilation failure.

[dpdk-dev] [PATCH v3 1/3] ixgbe: Use the rte_le_to_cpu_xx()/rte_cpu_to_le_xx() when reading/setting HW ring descriptor fields

[Vlad Zolotarov]

Fixed the above in ixgbe_rx_alloc_bufs() and in ixgbe_recv_scattered_pkts().

[dpdk-dev] [PATCH v3 2/3] ixgbe: Bug fix: Properly configure Rx CRC stripping for x540 devices

[Vlad Zolotarov]

According to x540 spec chapter 8.2.4.8.9 CRCSTRIP field of RDRXCTL should
be configured to the same value as HLREG0.RXCRCSTRP.

Clearing the RDRXCTL.RSCFRSTSIZE field for x540 is not required by the spec
but seems harmless.

[dpdk-dev] [PATCH v3 3/3] ixgbe: Unify the rx_pkt_bulk callback initialization

[Vlad Zolotarov]

   - Set the callback in a single function that is called from
     ixgbe_dev_rx_init() for a primary process and from eth_ixgbe_dev_init()
     for a secondary processes. This is instead of multiple, hard to track places.
   - Added ixgbe_hw.rx_bulk_alloc_allowed - see ixgbe_hw.rx_vec_allowed description below.
   - Added ixgbe_hw.rx_vec_allowed: like with Bulk Allocation, Vector Rx is
     enabled or disabled on a per-port level. All queues have to meet the appropriate
     preconditions and if any of them doesn't - the feature has to be disabled.
     Therefore ixgbe_hw.rx_vec_allowed will be updated during each queues configuration
     (rte_eth_rx_queue_setup()) and then used in rte_eth_dev_start() to configure the
     appropriate callbacks. The same happens with ixgbe_hw.rx_vec_allowed in a Bulk Allocation
     context.
   - Bugs fixed:
      - Vector scattered packets callback was called regardless the appropriate
        preconditions:
         - Vector Rx specific preconditions.
         - Bulk Allocation preconditions.
      - Vector Rx was enabled/disabled according to the last queue setting and not
        based on all queues setting (which may be different for each queue).

Just one nit:

+int __attribute__((weak)) ixgbe_rxq_vec_setup(
+	struct ixgbe_rx_queue __rte_unused *rxq)
+{

Please use notation:
int __attribute__((weak))
ixgbe_rxq_vec_setup(struct ixgbe_rx_queue __rte_unused *rxq)

To keep up with the rest of the code, plus makes much easier to read.

I took an example from kni/ethtool/igb/kcompat.h for a template but no 
problem.
Do u want me to respin or it's ok? I will use this format for the 
follow-up LRO patch anyway...

Doing that in LRO patch set is ok.
No need for respin that one, I think.

Yes, of course.
Just a note: I didn't merge it during my week-end and I think it is not
needed to ping only one day after.
Traffic on the list is becoming high; let's focus on important messages.
