40 * Bitfield annotations
41 *
42 * How to use: If you have a struct using bitfields, for example
43 *
44 * struct a {
45 * int x:8, y:8;
46 * };
47 *
48 * then this should be rewritten as
49 *
50 * struct a {
51 * kmemcheck_bitfield_begin(flags);
52 * int x:8, y:8;
53 * kmemcheck_bitfield_end(flags);
54 * };
55 *
56 * Now the "flags_begin" and "flags_end" members may be used to refer to the
57 * beginning and end, respectively, of the bitfield (and things like
58 * &x.flags_begin is allowed). As soon as the struct is allocated, the bit-
59 * fields should be annotated:
60 *
61 * struct a *a = kmalloc(sizeof(struct a), GFP_KERNEL);
62 * kmemcheck_annotate_bitfield(a, flags);

1104 * netdev_features_t features);
1105 * Called by core transmit path to determine if device is capable of
1106 * performing offload operations on a given packet. This is to give
1107 * the device an opportunity to implement any restrictions that cannot
1108 * be otherwise expressed by feature flags. The check is called with
1109 * the set of features that the stack has calculated and it returns
1110 * those the driver believes to be appropriate.

1127 * This function is used to specify the headroom that the skb must

1132 * int (*ndo_xdp)(struct net_device *dev, struct netdev_xdp *xdp);

1431 * struct net_device - The DEVICE structure.
1432 * Actually, this whole structure is a big mistake. It mixes I/O
1433 * data with strictly "high-level" data, and it has to know about
1434 * almost every data structure used in the INET module.
1435 *
1436 * @name: This is the first field of the "visible" part of this structure
1437 * (i.e. as seen by users in the "Space.c" file). It is the name
1438 * of the interface.

Here is an explanation of a rule violation arisen while checking your driver against a corresponding kernel.
Note that it may be false positive, i.e. there isn't a real error indeed. Please analyze a given error trace and related source code to understand whether there is an error in your driver.
Error trace column contains a path on which the given rule is violated. You can expand/collapse some entity classes by clicking on corresponding checkboxes in a main menu or in an advanced Others menu. Also you can expand/collapse each particular entity by clicking on +/-. In hovering on some entities you can see some tips. Also the error trace is bound with related source code. Line numbers may be shown as links on the left. You can click on them to open corresponding lines in source code.
Source code column contains a content of files related with the error trace. There is source code of your driver (note that there are some LDV modifications at the end), kernel headers and rule model. Tabs show a currently opened file and other available files. In hovering on them you can see full file names. On clicking a corresponding file content will be shown.
