Thank you for at least CC'ing me, but please remember to also CC intel- wired-...@lists.osuosl.org mailing list. It make it easier for me to add your patches to my queue and makes it visible for the developers/validation people who will be reviewing and testing your changes. > > Ding Tianhong (4): > ixgbe: sparc: rename the ARCH_WANT_RELAX_ORDER to > IXGBE_ALLOW_RELAXED_ORDER > ixgbe: ixgbevf: Clear the CONFIG_SPARC for ixgbevf and 82598 > ixgbe: move IXGBE_ALLOW_RELAXED_ORDER from architecture to driver > ixgbe: enable IXGBE_ALLOW_RELAXED_ORDER for ARM64 > > arch/Kconfig | 3 --- > arch/sparc/Kconfig | 1 - > drivers/net/ethernet/intel/Kconfig | 4 ++++ > drivers/net/ethernet/intel/ixgbe/ixgbe_82598.c | 4 ++-- > drivers/net/ethernet/intel/ixgbe/ixgbe_common.c | 2 +- > drivers/net/ethernet/intel/ixgbevf/ixgbevf_main.c | 2 +- > 6 files changed, 8 insertions(+), 8 deletions(-)
