PCI core will initialize device MSI/MSI-X capability in pci_msi_init_pci_dev(). So device driver should use pci_dev->msi_cap/msix_cap to determine whether the device support MSI/MSI-X instead of using pci_find_capability(pci_dev, PCI_CAP_ID_MSI/MSIX). Access to PCIe device config space again will consume more time. Signed-off-by:

With the restructuring of the lksctp.org site, we only allow bug reports through the SCTP mailing list linux-sctp@vger.kernel.org, not via SF, as SF is only used for web hosting and nothing more. While at it, also remove the obvious statement that bugs will be fixed and incooperated into the kernel. Signed-off-by:

Adds the new procfs knobs: /proc/sys/net/ipv4/conf/*/igmpv2_unsolicited_report_interval /proc/sys/net/ipv4/conf/*/igmpv3_unsolicited_report_interval Which will allow userspace configuration of the IGMP unsolicited report interval (see below) in milliseconds. The defaults are 10000ms for IGMPv2 and 1000ms for IGMPv3 in accordance with RFC2236 and RFC3376. Background: If an IGMP join packet is lost you will not receive data sent to the multicast group so if no data arrives from that multicast group in a period of time after the IGMP join a second IGMP join will be sent. The delay between joins is the "IGMP Unsolicited Report Interval". Prior to this patch this value was hard coded in the kernel to 10s for IGMPv2 and 1s for IGMPv3. 10s is unsuitable for some use-cases, such as IPTV as it can cause channel change to be slow in the presence of packet loss. This patch allows the value to be overridden from userspace for both IGMPv2 and IGMPv3 such that it can be tuned accoding to the network. Tested with Wireshark and a simple program to join a (non-existent) multicast group. The distribution of timings for the second join differ based upon setting the procfs knobs. igmpvX_unsolicited_report_interval is intended to follow the pattern established by force_igmp_version, and while a procfs entry has been added a corresponding sysctl knob has not as it is my understanding that sysctl is deprecated[1].

The procfs knob /proc/sys/net/ipv4/conf/*/force_igmp_version allows the IGMP protocol version to use to be explicitly set. As a side effect this caused the routing cache to be flushed as it was declared as a DEVINET_SYSCTL_FLUSHING_ENTRY. Flushing is unnecessary and this patch makes it so flushing does not occur. Requested by Hannes Frederic Sowa as he was reviewing other patches adding procfs entries. Suggested-by:

If an IGMP join packet is lost you will not receive data sent to the multicast group so if no data arrives from that multicast group in a period of time after the IGMP join a second IGMP join will be sent. The delay between joins is the "IGMP Unsolicited Report Interval". Previously this value was hard coded to be chosen randomly between 0-10s. This can be too long for some use-cases, such as IPTV as it can cause channel change to be slow in the presence of packet loss. The value 10s has come from IGMPv2 RFC2236, which was reduced to 1s in IGMPv3 RFC3376. This patch makes the kernel use the 1s value from the later RFC if we are operating in IGMPv3 mode. IGMPv2 behaviour is unaffected. Tested with Wireshark and a simple program to join a (non-existent) multicast group. The distribution of timings for the second join differ based upon setting /proc/sys/net/ipv4/conf/eth0/force_igmp_version. Signed-off-by:

In case of bond_add_vlan() failure currently we'll have the vlan's refcnt bumped up in all slaves, but it will never go down because it failed to get added to the bond, so properly unwind the added vlan if bond_add_vlan fails. Signed-off-by:

Now we have vlan_vids_add/del_by_dev() which serve the same purpose as bond's bond_add/del_vlans_on_slave() with the good side effect of reverting the changes if one of the additions fails. There's only 1 change in the behaviour of enslave: if adding of the vlans to the slave fails, we'll fail the enslaving because otherwise we might delete some vlan that wasn't added by the bonding. The only way this may happen is with ENOMEM currently, so we're in trouble anyway. Signed-off-by:

With GRO/LRO processing, there is a problem because Ip[6]InReceives SNMP counters do not count the number of frames, but number of aggregated segments. Its probably too late to change this now. This patch adds four new counters, tracking number of frames, regardless of LRO/GRO, and on a per ECN status basis, for IPv4 and IPv6. Ip[6]NoECTPkts : Number of packets received with NOECT Ip[6]ECT1Pkts : Number of packets received with ECT(1) Ip[6]ECT0Pkts : Number of packets received with ECT(0) Ip[6]CEPkts : Number of packets received with Congestion Experienced lph37:~# nstat | egrep "Pkts|InReceive" IpInReceives 1634137 0.0 Ip6InReceives 3714107 0.0 Ip6InNoECTPkts 19205 0.0 Ip6InECT0Pkts 52651828 0.0 IpExtInNoECTPkts 33630 0.0 IpExtInECT0Pkts 15581379 0.0 IpExtInCEPkts 6 0.0 Signed-off-by:

Cleanup gfar_start_xmit()'s fast path by factoring out "redundant" FCB insertion code (repeated gfar_add_fcb() calls and related) and by reducing the number of if() clauses (i.e. if(fcb) checks). Improve maintainability (e.g. there's less code and easier to read) also by introducing do_csum and do_vlan to mark the other 2 Tx TOE functionalities, following the same model as do_tstamp. fcb_len may also be 0 now, to mark that Tx FCB insertion conditions (do_csum, do_vlan, do_tstamp) have not been met.

Both [eTSEC76] and [eTSEC12] errata relate to Tx checksum generation (for some MPC83xx and MCP8548 older revisions). They require the same workaround: manual checksum computation and insertion, and disabling the H/W Tx csum acceleration feature (per frame) through Tx FCB (Frame Control Block) csum offload settings. The workaround for [eTSEC76] needs to be fixed because it currently fails to disable H/W Tx csum insertion via FCB. This patch fixes it and provides a common workaround implementation for both Tx csum errata. Signed-off-by:

We're already protected by RTNL lock, so nothing can happen to bond/its slaves, and thus the locking is useless here (both bond->lock and bond->curr_active_slave). Also, add ASSERT_RTNL() both to bond_set_rx_mode() and bond_hw_addr_swap() to catch possible uses of it without RTNL locking. This patch also saves us from a lockdep false-positive in bond_set_rx_mode() vs bond_hw_addr_swap().
