[RFCv6 PATCH net-next 00/19] net: extend the type of netdev_features_t to bitmap
by Jian Shen 21 Jul '22

21 Jul '22

For the prototype of netdev_features_t is u64, and the number of netdevice feature bits is 64 now. So there is no space to introduce new feature bit. This patchset try to solve it by change the prototype of netdev_features_t from u64 to structure below: typedef struct { DECLARE_BITMAP(bits, NETDEV_FEATURE_COUNT); } netdev_features_t; With this change, it's necessary to introduce a set of bitmap operation helpers for netdev features. As the nic drivers are not supposed to modify netdev_features directly, it also introduces wrappers helpers to this. [patch 1] To avoid mistake using NETIF_F_XXX as NETIF_F_XXX_BIT as input macroes for above helpers, remove all the macroes of NETIF_F_XXX. [patch 19] The features group macroes in netdev_features.h are replaced by a set of const features defined in netdev_features.c. [patch 2-3] For example: macro NETIF_F_ALL_TSO is replaced by netdev_all_tso_features There are some drivers(e.g. sfc) use netdev_features in global structure initialization. Changed the its netdev_features_t memeber to netdev_features_t *, and make it prefer to a netdev_features_t global variables. [patch 4] As suggestion from Andrew Lunn, I wrote some semantic patches to do the work(replacing the netdev features operator by helpers). [patch 7-18] To make the semantic patches simple, I split the complex opreation of netdev_features to simple logical operation. [patch 5, 6] With the prototype is no longer u64, the implementation of print interface for netdev features(%pNF) is changed to bitmap. [patch 19] The whole work is not complete yet. I just use these changes on several files(hns3 driver, sfc drivers, net/ethtool, net/core/dev.c), in order to show how these helpers will be used. I will apply these helpers to the whole tree later, sofar I want to get more suggestions for this scheme, any comments would be appreciated. The former discussion please see [1][2][3][4].
