In commit 6417f03132 ("module: remove never implemented
MODULE_SUPPORTED_DEVICE") the MODULE_SUPPORTED_DEVICE macro was
removed from the kerne entirely. Shortly before this patch was applied
mainline the commit 59ec7b89ed ("can: peak_usb: add forgotten
supported devices") was added to net/master. As this would result in a
merge conflict, let's revert this patch.

MODULE_SUPPORTED_DEVICE was added in pre-git era and never was

to have many more reliable mechanisms to determine if device is

In order to implement byte queue limits (bql) in CAN drivers, the length of the
CAN frame needs to be passed into the networking stack after queueing and after
transmission completion.
To avoid to calculate this length twice, extend can_get_echo_skb() to return
that value. Convert all users of this function, too.

Add a frame_len argument to can_put_echo_skb() which is used to save length of
the CAN frame into field frame_len of struct can_skb_priv so that it can be
later used after transmission completion. Convert all users of this function,
too.
Drivers which implement BQL call can_put_echo_skb() with the output of
can_skb_get_frame_len(skb) and drivers which do not simply pass zero as an
input (in the same way that NULL would be given to can_get_echo_skb()). This
way, we have a nice symmetry between the two echo functions.

The firmware on the original USB2CAN by Geschwister Schneider Technologie
Entwicklungs- und Vertriebs UG exchanges all data between the host and the
device in host byte order. This is done with the struct
gs_host_config::byte_order member, which is sent first to indicate the desired
byte order.
The widely used open source firmware candleLight doesn't support this feature
and exchanges the data in little endian byte order. This breaks if a device
with candleLight firmware is used on big endianess systems.
To fix this problem, all u32 (but not the struct gs_host_frame::echo_id, which
is a transparent cookie) are converted to __le32.
