void ixgbevf_set_ethtool_ops(struct net_device *netdev)
Added get_rxfh_indir_size, get_rxfh_key_size and get_rxfh ethtool_ops callbacks implementations. This enables the ethtool's "-x" and "-n rx-flow-hash" options for 82599 VF devices. Signed-off-by: Vlad Zolotarov <vladz@cloudius-systems.com> --- New in v3: - Added a proper support for x550 devices: return the correct redirection table size. New in v2: - Added a detailed description to the patch. --- drivers/net/ethernet/intel/ixgbevf/ethtool.c | 43 ++++++++++++++++++++++++++++ 1 file changed, 43 insertions(+)
