Maybe we can avoid the ARRAY_SIZE calls by doing something like: struct netdev_feature_set { unsigned int cnt; unsigned short feature_bits[]; }; #define DECLARE_NETDEV_FEATURE_SET(name, features...) \ static unsigned short __ ## name ## _s [] = {features}; \ struct netdev_feature_set name = { \ .cnt = ARRAY_SIZE(__ ## name ## _s), \ .feature_bits = {features}, \ } Then: DECLARE_NETDEV_FEATURE_SET(siena_offload_features, NETIF_F_IP_CSUM_BIT, NETIF_F_IPV6_CSUM_BIT, NETIF_F_RXHASH_BIT, NETIF_F_NTUPLE_BIT); etc.?
