SubjectRe: [PATCH net-next v3 4/4] enetc: Add RFS and RSS support
Hi Claudiu,

I love your patch! Perhaps something to improve:

[auto build test WARNING on net-next/master]

url: https://github.com/0day-ci/linux/commits/Claudiu-Manoil/Introduce-ENETC-ethernet-drivers/20181124-111823
config: x86_64-allmodconfig (attached as .config)
compiler: gcc-7 (Debian 7.3.0-1) 7.3.0
reproduce:
# save the attached .config to linux build tree
make ARCH=x86_64

All warnings (new ones prefixed by >>):

>> drivers/net/ethernet/freescale/enetc/enetc_hw.h:310:16: warning: cast to restricted __le64

vim +310 drivers/net/ethernet/freescale/enetc/enetc_hw.h
