net: fix endian check warning in etherdevice.h

2015-09-30T12:20:44Z

commit fbaff3ef859a86dc3df2128d2de9f8a6e255a967 upstream. Sparse builds have been warning for a really long time now that etherdevice.h has a conversion that is unsafe. include/linux/etherdevice.h:79:32: warning: restricted __be16 degrades to integer This code change fixes the issue and generates the exact same assembly before/after (checked on x86_64) Fixes: 2c722fe1c821 (etherdevice: Optimize a few is__ether_addr functions) Signed-off-by: Jesse Brandeburg CC: Joe Perches Signed-off-by: David S.

etherdevice: Use ether_addr_copy to copy an Ethernet address

2014-01-15T23:39:33Z

Some systems can use the normally known u16 alignment of Ethernet addresses to save some code/text bytes and cycles. This does not change currently emitted code on x86 by gcc 4.8. Signed-off-by: Joe Perches Signed-off-by: David S. Miller

etherdevice: Optimize a few is__ether_addr functions

2013-12-10T01:58:11Z

If CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS is set, several is__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 Signed-off-by: David S. Miller

etherdevice: Add ether_addr_equal_unaligned

2013-12-10T01:58:10Z

Add a generic routine to test if possibly unaligned to u16 Ethernet addresses are equal. If CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS is set, this uses the slightly faster generic routine ether_addr_equal, otherwise this uses memcmp. Signed-off-by: Joe Perches Signed-off-by: David S. Miller

ether_addr_equal: Optimize implementation, remove unused compare_ether_addr

2013-12-06T21:37:43Z

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.

[networking]device.h: Remove extern from function prototypes

2013-09-26T22:06:58Z

There are a mix of function prototypes with and without extern in the kernel sources. Standardize on not using extern for function prototypes. Function prototypes don't need to be written with extern. extern is assumed by the compiler. Its use is as unnecessary as using auto to declare automatic/local variables in a block.

net: etherdevice: add address inherit helper

2013-09-04T00:57:49Z

Some etherdevices inherit their address from a parent or master device. The addr_assign_type should be updated along with the address in these cases. Adding a helper function to simplify this. Signed-off-by: Bjørn Mork Signed-off-by: David S. Miller

net: split eth_mac_addr for better error handling

2013-01-21T19:07:44Z

When we set mac address, software mac address in system and hardware mac address all need to be updated. Current eth_mac_addr() doesn't allow callers to implement error handling nicely. This patch split eth_mac_addr() to prepare part and real commit part, then we can prepare first, and try to change hardware address, then do the real commit if hardware address is set successfully.

net: set dev->addr_assign_type correctly

eth: Rename and properly align br_reserved_address array

2012-11-03T01:34:05Z

Since this array is no longer part of the bridge driver, it should have an 'eth' prefix not 'br'. We also assume that either it's 16-bit-aligned or the architecture has efficient unaligned access. Ensure the first of these is true by explicitly aligning it. Signed-off-by: Ben Hutchings Acked-by: John Fastabend Signed-off-by: David S. Miller
