            Bug ID: 22
           Summary: Ixgbe driver sets RDRXCTL with the wrong RSCACKC and
                    FCOE_WRFIX values
           Product: DPDK
           Version: unspecified
          Hardware: All
                OS: All
            Status: CONFIRMED
          Severity: normal
          Priority: Normal
         Component: ethdev
          Assignee: dev@dpdk.org
          Reporter: solal.pirelli@gmail.com
  Target Milestone: ---

The Intel 82599 data sheet
(https://www.intel.com/content/dam/www/public/us/en/documents/datasheets/82=
599-10-gbe-controller-datasheet.pdf,
=C2=A78.2.3.8.8) states that the RDRXCTL register's RSCACKC (bit 25) and FC=
OE_WRFIX
(bit 26) values, while reserved, should be set to 1 by software.

The ixgbe driver does not do that, e.g. in ixgbe_dev_rx_init
(http://dpdk.org/browse/dpdk/tree/drivers/net/ixgbe/ixgbe_rxtx.c?h=3Dv18.02=
#n4855).
