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.

help
|
|
This option enables additional sanity checks in the driver,
|
|
that compares various internal counters with the in chip
|
|
variants. This comes with a runtime overhead.
|
|
Disable if unsure.
