None of these files are actually using any __init type directives and hence don't need to include <linux/init.h>. Most are just a left over from __devinit and __cpuinit removal, or simply due to code getting copied from one driver to the next.

With the recent changes for how we compute the skb truesize it occurs to me we are probably going to have a lot of calls to skb_end_pointer - skb->head. Instead of running all over the place doing that it would make more sense to just make it a separate inline skb_end_offset(skb) that way we can return the correct value without having gcc having to do all the optimization to cancel out skb->head - skb->head.

If we wait for the once-per-second cleanup to free transmit SKBs, sockets with small transmit buffer sizes might spend most of their time blocked waiting for the cleanup. Normally we do a cleanup for each transmitted packet. We add a watchdog type timer so that we also schedule a timeout for 150uS after a packet is transmitted. The watchdog is reset for each transmitted packet, so for high packet rates, it never expires. At these high rates, the cleanups are done for each packet so the extra watchdog initiated cleanups are neither needed nor triggered.

Octeon ethernet hardware can handle NETIF_F_SG, so we enable it. A gather list of up to six fragments will fit in the SKB's CB structure, so no extra memory is required.

After aligning the blocks returned by kmalloc, we need to save the original pointer so they can be correctly freed. There are no guarantees about the alignment of SKB data, so we need to handle worst case alignment. Since right shifts over subtraction have no distributive property, we need to fix the back pointer calculation.

The existing code had the following race: Thread-1 Thread-2 inc/read in_use inc/read in_use inc tx_free_list[qos].len inc tx_free_list[qos].len The actual in_use value was incremented twice, but thread-1 is going to free memory based on its stale value, and will free one too many times. The result is that memory is freed back to the kernel while its packet is still in the transmit buffer. If the memory is overwritten before it is transmitted, the hardware will put a valid checksum on it and send it out (just like it does with good packets). If by chance the TCP flags are clobbered but not the addresses or ports, the result can be a broken TCP stream. The fix is to track the number of freed packets in a single location (a Fetch-and-Add Unit register). That way it can never get out of sync with itself. We try to free up to MAX_SKB_TO_FREE (currently 10) buffers at a time. If fewer are available we adjust the free count with the difference. The action of claiming buffers to free is atomic so two threads cannot claim the same buffers.

Convert the driver to use net_device_ops as it is now mandatory. Also compensate for the removal of struct sk_buff's dst field.

The octeon-ethernet driver supports the sgmii, rgmii, spi, and xaui ports present on the Cavium OCTEON family of SOCs. These SOCs are multi-core mips64 processors with existing support over in arch/mips. The driver files can be categorized into three basic groups: 1) Register definitions, these are named cvmx-*-defs.h 2) Main driver code, these have names that don't start cvmx-. 3) Interface specific functions and other utility code, names starting with cvmx- Signed-off-by: NDavid Daney <ddaney@caviumnetworks.com> Signed-off-by: NRalf Baechle <ralf@linux-mips.org>
