2008-11-24eth: Declare an optimized compare_ether_addr_64bits() functionEric Dumazet1-0/+42
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.

2007-10-11[NET]: Move hardware header operations out of netdevice.Stephen Hemminger1-8/+12
Since hardware header operations are part of the protocol class not the device instance, make them into a separate object and save memory. Signed-off-by: Stephen Hemminger <shemminger@linux-foundation.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2007-07-11[CORE] Stack changes to add multiqueue hardware support APIPeter P Waskiewicz Jr1-1/+2
Add the multiqueue hardware device support API to the core network stack. Allow drivers to allocate multiple queues and manage them at the netdev level if they choose to do so. Added a new field to sk_buff, namely queue_mapping, for drivers to know which tx_ring to select based on OS classification of the flow.

2007-07-11[NET]: Kill eth_copy_and_sum().David S. Miller1-6/+0
It hasn't "summed" anything in over 7 years, and it's just a straight mempcy ala skb_copy_to_linear_data() so just get rid of it. Signed-off-by: David S. Miller <davem@davemloft.net>
2007-05-07uml: improve checking and diagnostics of ethernet MACsPaolo 'Blaisorblade' Giarrusso1-0/+12
Improve checking and diagnostics for broadcast and multicast Ethernet MAC addresses, and distinguish between those cases in output; also make sure the device is assigned a MAC address valid only locally to avoid collisions.

2006-01-04[NET]: Don't exclude broadcast addresses from is_multicast_ether_addr()Stephen Hemminger1-1/+2
The check for multicast shouldn't exclude broadcast type addresses. This reverts the incorrect change done in 2.6.13. The broadcast address is a multicast address and should be excluded from being a valid_ether_address for use in bridging or device address.

2005-11-03[ETHERNET]: Add ether stuff to docbookStephen Hemminger1-9/+15
Fix up etherdevice docbook comments and make them (and other networking stuff) get dragged into the kernel-api. Delete the old 8390 stuff, it really isn't interesting anymore. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Arnaldo Carvalho de Melo <acme@mandriva.com>
2005-11-03[ETHERNET]: Optimize is_broadcast_ether_addrStephen Hemminger1-2/+1
Optimize the match for broadcast address by using bit operations instead of comparison. This saves a number of conditional branches, and generates smaller code. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Arnaldo Carvalho de Melo <acme@mandriva.com>

2005-06-29[NET]: Add missing include to linux/netdevice.hArnd Bergmann1-0/+1
linux/etherdevice.h can't be included standalone at the moment, which is required in order to sort the header files in the recommended alphabetic order.

2005-05-30[NET]: Add is_multicast_ether_addr() in include/linux/etherdevice.hMichael Ellerman1-4/+18
This patch adds is_multicast_ether_addr() to go along with is_valid_ether_addr() and friends. It then changes is_valid_ether_addr() to use the new macro, and fixes up the comment on that function to move implementation details out of the API doco.

2005-04-17Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds1-0/+88
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
