To get more performance from using multiple tx queues one needs a per tx queue napi. Move tx napi from per adapter struct into per tx queue struct. Patch that actually enables multiple tx queues will follow. Signed-off-by:

To support NICs that allow for more than one tx queue it is required to detect NIC type early during probe. This is moves NIC type detection before netdev_alloc to prepare for that. Signed-off-by:

Torin Cooper-Bennun authored
Introduce masks for the three RXESC fields (RBDS, F1DS, F0DS) and the one TXESC field (TBDS). Update m_can_chip_config() to explicitly set all four fields to the 64-byte option (0x7) (and these defs are renamed to be more concise). This is an improvement in maintainability, and also makes it easier to implement more flexible configuration of the M_CAN buffers in the future.

Oliver Hartkopp authored
The struct can_frame and struct canfd_frame intentionally share the same layout to be able to write CAN frame content into a CAN FD frame structure. When this is done the former differentiation via CAN_MTU / CANFD_MTU is lost. CANFD_FDF allows programmers to mark CAN FD frames in the case of using struct canfd_frame for mixed CAN/CAN FD content (dual use). N.B. the Kernel APIs do NOT provide mixed CAN / CAN FD content inside of struct canfd_frame therefore the CANFD_FDF flag is disregarded by Linux.

Fix the sparse warnings in the ixgbe crypto offload code. These changes were made in the most conservative way (force cast) in order to hopefully not break the code. I suspect that the code might still be broken on big-endian architectures, but no one is complaining, so I'm just leaving it functionally the same. Signed-off-by:

The ixgbe hardware needs some very specific programming for certain registers, which led to some misguided usage of ntohs instead of using be16_to_cpu(), as well as a home grown swap followed by an ntohs. Sparse didn't like this at all, and this fixes the C=2 build, with code that uses native kernel interface. Signed-off-by:
