Ixgbe driver writes to reserved bit in the EIMC register

Bug ID: 23
Summary: Ixgbe driver writes to reserved bit in the EIMC
register
Product: DPDK
Version: unspecified
Hardware: All
OS: All
Status: CONFIRMED
Severity: minor
Priority: Normal
Component: ethdev
Assignee: [email protected]
Reporter: [email protected]
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,
§8.2.3.5.4) states that bit 31 of the EIMC register is reserved.

However, the ixgbe driver writes to this bit anyway, e.g. in ixgbe_stop_adapter_generic
(http://dpdk.org/browse/dpdk/tree/drivers/net/ixgbe/base/ixgbe_common.c?h=v18.02#n1126
with the mask defined as all-1s in
http://dpdk.org/browse/dpdk/tree/drivers/net/ixgbe/base/ixgbe_type.h?h=v18.02#n2047).
