* ethtool: Add GGRO and SGRO opsHerbert Xu2008-12-16
| | | | | | | | | This patch adds the ethtool ops to enable and disable GRO. It also makes GRO depend on RX checksum offload much the same as how TSO depends on SG support. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>

* ethtool: EEPROM dump no longer works for tg3 and natsemiMandeep Singh Baines2008-04-24
| | | | | | | | | | | | | | | | | | In the ethtool user-space application, tg3 and natsemi over-ride the default implementation of dump_eeprom(). In both tg3_dump_eeprom() and natsemi_dump_eeprom(), there is a magic number check which is not present in the default implementation. Commit b131dd5d ("[ETHTOOL]: Add support for large eeproms") snipped the code which copied the ethtool_eeprom structure back to user-space. tg3 and natsemi are over-writing the magic number field and then checking it in user-space. With the ethtool_eeprom copy removed, the check is failing. The fix is simple. Add the ethtool_eeprom copy back. Signed-off-by: Mandeep Singh Baines <msb@google.com> Signed-off-by: David S.

* [ETHTOOL]: Add support for large eepromsMandeep Singh Baines2008-04-15
| | | | | | | | | | | | | | | Currently, it is not possible to read/write to an eeprom larger than 128k in size because the buffer used for temporarily storing the eeprom contents is allocated using kmalloc. kmalloc can only allocate a maximum of 128k depending on architecture. Modified ethtool_get/set_eeprom to only allocate a page of memory and then copy the eeprom a page at a time. Updated original patch as per suggestions from Joe Perches.

* [ETHTOOL] Provide default behaviors for a few ethtool sub-ioctlsJeff Garzik2007-10-10
| | | | | | | | | | | | | | | | | | | | | | | | | For the operations get-tx-csum get-sg get-tso get-ufo the default ethtool_op_xxx behavior is fine for all drivers, so we permit op==NULL to imply the default behavior. This provides a more uniform behavior across all drivers, eliminating ethtool(8) "ioctl not supported" errors on older drivers that had not been updated for the latest sub-ioctls. The ethtool_op_xxx() functions are left exported, in case anyone wishes to call them directly from a driver-private implementation -- a not-uncommon case. Should an ethtool_op_xxx() helper remain unused for a while, except by net/core/ethtool.c, we can un-export it at a later date.

* [NET]: Make the device list and device lookups per namespace.Eric W. Biederman2007-10-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch makes most of the generic device layer network namespace safe. This patch makes dev_base_head a network namespace variable, and then it picks up a few associated variables. The functions: dev_getbyhwaddr dev_getfirsthwbytype dev_get_by_flags dev_get_by_name __dev_get_by_name dev_get_by_index __dev_get_by_index dev_ioctl dev_ethtool dev_load wireless_process_ioctl were modified to take a network namespace argument, and deal with it. vlan_ioctl_set and brioctl_set were modified so their hooks will receive a network namespace argument. So basically anthing in the core of the network stack that was affected to by the change of dev_base was modified to handle multiple network namespaces. The rest of the network stack was simply modified to explicitly use &init_net the initial network namespace. This can be fixed when those components of the network stack are modified to handle multiple network namespaces. For now the ifindex generator is left global. Fundametally ifindex numbers are per namespace, or else we will have corner case problems with migration when we get that far. At the same time there are assumptions in the network stack that the ifindex of a network device won't change. Making the ifindex number global seems a good compromise until the network stack can cope with ifindex changes when you change namespaces, and the like. Signed-off-by: Eric W.

* [NET]: ethtool_perm_addr only has one implementationMatthew Wilcox2007-07-31

* [NET]: ethtool ops are the only wayMatthew Wilcox2007-07-31
| | | | | | | | | | | | | | | During the transition to the ethtool_ops way of doing things, we supported calling the device's ->do_ioctl method to allow unconverted drivers to continue working. Those days are long behind us, all in-tree drivers use the ethtool_ops way, and so we no longer need to support this. The bonding driver is the biggest beneficiary of this; it no longer needs to call ioctl() as a fallback if ethtool_ops aren't supported. Also put a proper copyright statement on ethtool.c.

| | | | | | | | | | | The current stack treats NETIF_F_HW_CSUM and NETIF_F_NO_CSUM identically so we test for them in quite a few places.

* [IPv4/IPv6]: UFO Scatter-gather approachAnanda Raju2005-10-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Attached is kernel patch for UDP Fragmentation Offload (UFO) feature. 1. This patch incorporate the review comments by Jeff Garzik. 2. Renamed USO as UFO (UDP Fragmentation Offload) 3. udp sendfile support with UFO This patches uses scatter-gather feature of skb to generate large UDP datagram. Below is a "how-to" on changes required in network device driver to use the UFO interface. UDP Fragmentation Offload (UFO) Interface: ------------------------------------------- UFO is a feature wherein the Linux kernel network stack will offload the IP fragmentation functionality of large UDP datagram to hardware. This will reduce the overhead of stack in fragmenting the large UDP datagram to MTU sized packets 1) Drivers indicate their capability of UFO using dev->features |= NETIF_F_UFO | NETIF_F_HW_CSUM | NETIF_F_SG NETIF_F_HW_CSUM is required for UFO over ipv6. 2) UFO packet will be submitted for transmission using driver xmit routine. UFO packet will have a non-zero value for "skb_shinfo(skb)->ufo_size" skb_shinfo(skb)->ufo_size will indicate the length of data part in each IP fragment going out of the adapter after IP fragmentation by hardware. skb->data will contain MAC/IP/UDP header and skb_shinfo(skb)->frags[] contains the data payload. The skb->ip_summed will be set to CHECKSUM_HW indicating that hardware has to do checksum calculation. Hardware should compute the UDP checksum of complete datagram and also ip header checksum of each fragmented IP packet. For IPV6 the UFO provides the fragment identification-id in skb_shinfo(skb)->ip6_frag_id. The adapter should use this ID for generating IPv6 fragments.

* Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds2005-04-16
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!
