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_rx_offload_get_echo_skb() to return that value. Convert all users of this function, too. Reviewed-by:

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. Link: https://lore.kernel.org/r/20210111061335.39983-1-mailhol.vincent@wanadoo.frSigned-off-by:

can: length: can_skb_get_frame_len(): introduce function to get data length of frame in data link layer This patch adds the function can_skb_get_frame_len() which returns the length of a CAN frame on the data link layer, including Start-of-frame, Identifier, various other bits, the actual data, the CRC, the End-of-frame, the Inter frame spacing.

If the length paramter in len2dlc() exceeds the size of the len2dlc array, we return 0xF. This is equal to the last 16 members of the array. This patch removes these members from the array, uses ARRAY_SIZE() for the length check, and returns CANFD_MAX_DLC (which is 0xf). Reviewed-by:

The IPA driver depends on some SMEM functionality (qcom_smem_init(), qcom_smem_alloc(), and qcom_smem_virt_to_phys()), but this is not reflected in the configuration dependencies. Add a dependency on QCOM_SMEM to avoid attempts to build the IPA driver without SMEM. This avoids a link error for certain configurations. Reported-by:

Patch didn't fix any issue, just improve parse flow and align ipv4 parse flow with ipv6 parse flow. Currently ipv4 kenguru parser first check IP protocol(TCP/UDP) and then destination IP address. Patch introduce reverse ipv4 parse, first destination IP address parsed and only then IP protocol. This would allow extend capability for packet L4 parsing and align ipv4 parsing flow with ipv6.

bareudp_dellink() only needs the device list to hand it to unregister_netdevice_queue(). We can pass NULL in, and unregister_netdevice_queue() will do the unregistering. There is no chance for batching on the error path, anyway. Suggested-by:
