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.pire...@gmail.com
Target Milestone: ---
The Intel 82599 data sheet
(https://www.intel.com/content/dam/www/public/us/en/documents/datasheets/82599-10-gbe-controller-datasheet.pdf,
ยง8.2.3.8.8) states that the RDRXCTL register's RSCACKC (bit 25) and FCOE_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=v18.02#n4855).
