BCM471X and BCM535X are of the same family (from what I can derive from internal documents). Group them into the case statement together, which results in more code reuse. Also, use existing helper variables to make the code a little more readable too. Signed-off-by:

Since commit c0f031bc ("nfp_net: use alloc_frag() and build_skb()") we are allocating buffers which have to hold both the data and skb to be created in place by build_skb(). FW should only be told about the buffer space it can DMA to, that is without the build_skb() headroom and tailroom. Note: firmware applications should validate the buffers against both MTU and free list buffer size so oversized packets would not pass through the NIC anyway.

Fix a bug in the 'bgmac' driver init sequence that blind writes for init sequence where it should preserve most bits other than the ones it is deliberately manipulating. The code now checks to see if the adapter needs to be brought out of reset (where as before it was doing an IDM write to bring it out of reset regardless of whether it was in reset or not). Also, removed unnecessary usleeps (as there is already a read present to flush the IDM writes). Signed-off-by:

On architectures that have a cache line size larger than 64 Bytes we start running into issues where the amount of headroom for the frame starts shrinking. The size of skb_shared_info on a system with a 64B L1 cache line size is 320. This increases to 384 with a 128B cache line, and 512 with a 256B cache line. In addition the NET_SKB_PAD value increases as well consistent with the cache line size. As a result when we get to a 256B cache line as seen on the s390 we end up 768 bytes used by padding and shared info leaving us with only 1280 bytes to use for data storage. On architectures such as this we should default to using 3K Rx buffers out of a 8K page instead of trying to do 1.5K buffers out of a 4K page. To take all of this into account I have added one small check so that we compare the max_frame to the amount of actual data we can store. This was already occurring for igb, but I had overlooked it for ixgbe as it doesn't have strict limits for 82599 once we enable jumbo frames. By adding this check we will automatically enable 3K Rx buffers as soon as the maximum frame size we can handle drops below the standard Ethernet MTU. I also went through and fixed one small typo that I found where I had left an IGB in a variable name due to a copy/paste error. Signed-off-by:

Currently ixgbe_set_rxfh() updates the rss_key copy in the driver memory, but does not push the new value into the h/w. This commit add a new helper for the latter operation and call it in ixgbe_set_rxfh(), so that the h/w rss key value can be really updated via ethtool. Signed-off-by:

Even if bus is not hot-pluggable, devices can be unbound from the driver via sysfs, so we should not be using __exit annotations on remove() methods. The only exception is drivers registered with platform_driver_probe() which specifically disables sysfs bind/unbind attributes. Signed-off-by:

Some configurations require the use of the hardware's MDIO support to communicate with external PHYs. The MDIO commands indicate completion through the device interrupt. When bringing down the device the interrupts were released before stopping the external PHY, resulting in MDIO command timeouts. Move the stopping of the PHY to before the releasing of the interrupts. Signed-off-by:

Now that %z is standartised in C99 there is no reason to support %Z. Unlike %L it doesn't even make format strings smaller. Use BUILD_BUG_ON in a couple ATM drivers. In case anyone didn't notice lib/vsprintf.o is about half of SLUB which is in my opinion is quite an achievement. Hopefully this patch inspires someone else to trim vsprintf.c more.
