Subject: questions about netdevice->features

Hi,

I noticed that the enum NETIF_F_XXX_BIT has already used 64 bits since

NETIF_F_HW_HSR_DUP_BIT being added, while the prototype of 
netdev_features_t

is u64.   So there is no useable bit for new feature if I understand 
correct.


Is there any solution or plan for it ?



Thanks,

shen jian
