etherdev: Fix sparse error, make test usable by other functions This change does two things. First it fixes a sparse error for the fact that the __be16 degrades to an integer. Since that is actually what I am kind of doing I am simply working around that by forcing both sides of the comparison to u16. Also I realized on some compilers I was generating another instruction for big endian systems such as PowerPC since it was masking the value before doing the comparison. So to resolve that I have simply pulled the mask out and wrapped it in an #ifndef __BIG_ENDIAN. Lastly I pulled this all out into its own function. I notices there are similar checks in a number of other places so this function can be reused there to help reduce overhead in these paths as well.

net: Add functions for handling padding frame and adding to length This patch adds two new helper functions skb_put_padto and eth_skb_pad. These functions deviate from the standard skb_pad or skb_padto in that they will also update the length and tail pointers so that they reflect the padding added to the frame. The eth_skb_pad helper is meant to be used with Ethernet devices to update either Rx or Tx frames so that they report the correct size. The skb_put_padto helper is meant to be used primarily in the transmit path for network devices that need frames to be padded up to some minimum size and don't wish to simply update the length somewhere external to the frame. The motivation behind this is that there are a number of implementations throughout the network device drivers that are all doing the same thing, but each a little bit differently and as a result several implementations contain bugs such as updating the length without updating the tail offset and other similar issues.

I have split __skb_get_poff into two functions, the first is skb_get_poff and it retains the functionality of the original __skb_get_poff. The other function is __skb_get_poff which now works much like __skb_flow_dissect in relation to skb_flow_dissect in that it provides the same functionality but works with just a data buffer and hlen instead of needing an skb.

etherdevice: Optimize a few is_<foo>_ether_addr functions If CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS is set, several is_<foo>_ether_addr functions can be slightly improved by using u32 dereferences. I believe all current uses of is_zero_ether_addr and is_broadcast_ether_addr are u16 aligned, so always use u16 references to improve those functions performance. Document the u16 alignment requirements. Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: David S. Miller <davem@davemloft.net>

ether_addr_equal: Optimize implementation, remove unused compare_ether_addr Add a new check for CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS to reduce the number of or's used in the ether_addr_equal comparison to very slightly improve function performance. Simplify the ether_addr_equal_64bits implementation. Integrate and remove the zap_last_2bytes helper as it's now used only once. Remove the now unused compare_ether_addr function. Update the unaligned-memory-access documentation to remove the compare_ether_addr description and show how unaligned accesses could occur with ether_addr_equal.

net, ixgbe: handle link local multicast addresses in SR-IOV mode In SR-IOV mode the PF driver acts as the uplink port and is used to send control packets e.g. lldpad, stp, etc. eth0.1 eth0.2 eth0 VF VF PF | | | <-- stand-in for uplink | | | -------------------------- | Embedded Switch | -------------------------- | MAC <-- uplink But the embedded switch is setup to forward multicast addresses to all interfaces both VFs and PF and onto the physical link. This results in reserved MAC addresses used by control protocols to be forwarded over the switch onto the VF. In the LLDP case the PF sends an LLDPDU and it is currently being forwarded to all the VFs who then see the PF as a peer. This is incorrect. This patch adds the multicast addresses to the RAR table in the hardware to prevent this behavior.

Removed the second parameter (u8 *hwaddr), it's redundant since the also given net_device already contains net_device->dev_addr. Set it directly. Adapt igbvf and ixgbevf to the changed function. Small fix for ixgbevf_probe(): if ixgbevf_sw_init() fails (which means the device got no dev_addr) handle the error and jump to err_sw_init as already done by igbvf in similar case.

sysfs: add attribute to indicate hw address assignment type Add addr_assign_type to struct net_device and expose it via sysfs. This new attribute has the purpose of giving user-space the ability to distinguish between different assignment types of MAC addresses. For example user-space can treat NICs with randomly generated MAC addresses differently than NICs that have permanent (locally assigned) MAC addresses. For the former udev could write a persistent net rule by matching the device path instead of the MAC address. There's also the case of devices that 'steal' MAC addresses from slave devices. In which it is also be beneficial for user-space to be aware of the fact. This patch also introduces a helper function to assist adoption of drivers that generate MAC addresses randomly.

eth: Declare an optimized compare_ether_addr_64bits() function Linus mentioned we could try to perform long word operations, even on potentially unaligned addresses, on x86 at least. David mentioned the HAVE_EFFICIENT_UNALIGNED_ACCESS test to handle this on all arches that have efficient unailgned accesses. I tried this idea and got nice assembly on 32 bits: 158: 33 82 38 01 00 00 xor 0x138(%edx),%eax 15e: 33 8a 34 01 00 00 xor 0x134(%edx),%ecx 164: c1 e0 10 shl $0x10,%eax 167: 09 c1 or %eax,%ecx 169: 74 0b je 176 <eth_type_trans+0x87> And very nice assembly on 64 bits of course (one xor, one shl) Nice oprofile improvement in eth_type_trans(), 0.17 % instead of 0.41 %, expected since we remove 8 instructions on a fast path. This patch implements a compare_ether_addr_64bits() function, that uses the CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS ifdef to efficiently perform the 6 bytes comparison on all capable arches.
