Some CAN interfaces only support fixed fixed bitrates. This patch adds a netlink interface to get the list of the CAN interface's fixed bitrates and data bitrates. Inside the driver arrays of supported data- bitrate values are defined. const u32 drvname_bitrate[] = { 20000, 50000, 100000 }; const u32 drvname_data_bitrate[] = { 200000, 500000, 1000000 }; struct drvname_priv *priv; priv = netdev_priv(dev); priv->bitrate_const = drvname_bitrate; priv->bitrate_const_cnt = ARRAY_SIZE(drvname_bitrate); priv->data_bitrate_const = drvname_data_bitrate; priv->data_bitrate_const_cnt = ARRAY_SIZE(drvname_data_bitrate);
