can: dev: move driver related infrastructure into separate subdir This patch moves the CAN driver related infrastructure into a separate subdir. It will be split into more files in the coming patches.

Revert "can: raw: instantly reject unsupported CAN frames" This reverts commit 1a620a723853a0f49703c317d52dc6b9602cbaa8 and its follow-up fixes for the introduced dependency issues. commit 1a620a723853 ("can: raw: instantly reject unsupported CAN frames") commit cb2dc6d2869a ("can: Kconfig: select CAN driver infrastructure by default") commit 6abd4577bccc ("can: fix build dependency") commit 5a5aff6338c0 ("can: fix build dependency") The entire problem was caused by the requirement that a new network layer feature needed to know about the protocol capabilities of the CAN devices. Instead of accessing CAN device internal data structures which caused the dependency problems a better approach has been developed which makes use of CAN specific ml_priv data which is accessible from both sides.

can: Kconfig: turn menu "CAN Device Drivers" into a menuconfig using CAN_DEV In the next patches, the software/virtual drivers (slcan, v(x)can) will depend on drivers/net/can/dev/skb.o. This patch changes the scope of the can-dev module to include the above mentioned drivers. To do so, we reuse the menu "CAN Device Drivers" and turn it into a configmenu using the config symbol CAN_DEV (which we released in previous patch). Also, add a description to this new CAN_DEV menuconfig. The symbol CAN_DEV now only triggers the build of skb.o. For this reasons, all the macros from linux/module.h are deported from drivers/net/can/dev/dev.c to drivers/net/can/dev/skb.c. Finally, drivers/net/can/dev/Makefile is adjusted accordingly.

can: bittiming: move bittiming calculation functions to calc_bittiming.c The canonical way to select or deselect an object during compilation is to use this pattern in the relevant Makefile: bar-$(CONFIG_FOO) := foo.o bittiming.c instead uses some #ifdef CONFIG_CAN_CALC_BITTIMG. Create a new file named calc_bittiming.c with all the functions which are conditionally compiled with CONFIG_CAN_CALC_BITTIMG and modify the Makefile according to above pattern.

can: Kconfig: add CONFIG_CAN_RX_OFFLOAD Only a few drivers rely on the CAN rx offload framework (as of the writing of this patch, only four: flexcan, m_can, mcp251xfd and ti_hecc). Split it out of can-dev and add a new config symbol: CAN_RX_OFFLOAD. The drivers relying on CAN rx offload are in different sub folders. Make CAN_RX_OFFLOAD an hidden option and tag all the drivers depending on that feature with "select CAN_RX_OFFLOAD" so that the option gets automatically enabled if and only if one of those drivers is chosen.
