In case of allocation failure, the actual ring size is rounded down to nearest power of 2. The remaining descriptors are freed. The CQ and SRQ are allocated with the actual size and the mask is updated. Signed-off-by:

Sinec the TCPv6 GRO functions are used in the same file where they are defined, we do not need to export them. This was a cut-n-paste from the IPv4 code which does need to export them. Signed-off-by:

The current driver tries to re-register the DCA requester after reset and this is not correct. This change makes it so all we are doing is resetting the DCA registers after reset and not re-adding the requester. Signed-off-by:

The current driver is re-registering the DCA requester after every reset. Instead of doing this we should only be updating the on board DCA registers and not unregistering/re-registering our requester. Signed-off-by:

Patch to add the ability to detect drops in hardware interfaces via dropwatch. Adds a tracepoint to net_rx_action to signal everytime a napi instance is polled. The dropmon code then periodically checks to see if the rx_frames counter has changed, and if so, adds a drop notification to the netlink protocol, using the reserved all-0's vector to indicate the drop location was in hardware, rather than somewhere in the code.

The the PACKET_ADD_MEMBERSHIP and the PACKET_DROP_MEMBERSHIP setsockopt calls for af_packet already has all of the infrastructure needed to subscribe to multiple mac addresses. All that is missing is a flag to say that the address we want to listen on is a unicast address. So introduce PACKET_MR_UNICAST and wire it up to dev_unicast_add and dev_unicast_delete. Additionally I noticed that errors from dev_mc_add were not propagated from packet_dev_mc so fix that. Signed-off-by:

z/VM Virtual Switch Port Isolation allows guests on a VLAN UNAWARE virtual switch to be isolated from other guests on the VSWITCH. (See z/VM Apars VM64281 and VM64463). The Linux qeth driver is affected, because it has to handle new error codes introduced with the z/VM VSWITCH Port Isolation support. Signed-off-by:

If a qeth device is plugged off, setting the device online stops in state HARDSETUP and a failure is reported to the base cio-layer causing halt/clear to be invoked. Replugging the device again triggers a qeth recovery without notification of the cio-layer. If a device is ungrouped in this state, the qeth set_offline function is not invoked, because the corresponding ccwgroup device is not in state ONLINE. Then incoming traffic is still handled by the qdio layer resulting in a crash in qeth_l<x>_qdio_input_handler, because (part of) the qeth data structures for this device are already removed. Solution: After replugging the device qeth recovery should lead to a working net device. Thus a "LAN offline" result when setting a qeth device online must not report a failure to the base cio-layer.

Grrr. Some days it feels like all of the good names are already taken. Let's just rename the two static users in arm and avr32 to get this sorted out. Signed-off-by:

be sent periodically. The rs_delay can be speficied when adding the PRL entry and defaults to 15 minutes. The RS is sent from every link local adress that's assigned to the tunnel interface. It's directed to the (guessed) linklocal address of the router and is sent through the tunnel. Better: send to ff02::2 encapsuled in unicast directed to router-v4. Signed-off-by:

The DHCP spec allows the server to specify the MTU. This can be useful for netbooting with UDP-based NFS-root on a network using jumbo frames. This patch allows the kernel IP autoconfiguration to handle this option correctly. It would be possible to use initramfs and add a script to set the MTU, but that seems like a complicated solution if no initramfs is otherwise necessary, and would bloat the kernel image more than this code would. This patch was originally submitted to LKML in 2003 by Hans-Peter Jansen. Signed-off-by:

nlmsg_new() adds the size of the netlink header to the value that has been passed as parameter. If NLMSG_GOODSIZE is selected, we request an allocation of one memory page plus the size of the header. Instead, NLMSG_DEFAULT_SIZE should be used since it already substracts the size of the Netlink header. I have the impression that the similar naming in both constant is error prone when using it with nlmsg_new(). This is already documented in include/net/netlink.h Signed-off-by:

The SFF specification for Direct Attach cable detection has now been ratified. Previously, DA cable detect was looking at the Twinaxial bit in byte 9 of the SFP+ EEPROM. The spec now defines active and passive DA cables in byte 8 of the SFP+ EEPROM. This patch changes the cable detection for both 82598 and 82599 SFP+ adapters to conform to the new spec.
