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).
Hi konstantin, can you please take a look? Thanks

In principle, the code in base folder will not be changed if there is no bug or issue. By now, the using of this reserved bit have no bad impact. So it is not a bug, and change state to resolve and wontfix.
