2010-03-28bonding: fix broken multicast with round-robin modeAndy Gospodarek1-8/+32
Round-robin (mode 0) does nothing to ensure that any multicast traffic originally destined for the host will continue to arrive at the host when the link that sent the IGMP join or membership report goes down. One of the benefits of absolute round-robin transmit. Keeping track of subscribed multicast groups for each slave did not seem like a good use of resources, so I decided to simply send on the curr_active slave of the bond (typically the first enslaved device that is up). This makes failover management simple as IGMP membership reports only need to be sent when the curr_active_slave changes. I tested this patch and it appears to work as expected.

2010-03-27e1000: do not modify tx_queue_len on link speed changeEmil Tantilov2-9/+1
Previously the driver tweaked txqueuelen to avoid false Tx hang reports seen at half duplex. This had the effect of overriding user set values on link change/reset. Testing shows that adjusting only the timeout factor is sufficient to prevent Tx hang reports at half duplex. This patch removes all instances of tx_queue_len in the driver.

2010-03-27net: ipmr/ip6mr: prevent out-of-bounds vif_table accessNicolas Dichtel2-8/+14
When cache is unresolved, c->mf[6]c_parent is set to 65535 and minvif, maxvif are not initialized, hence we must avoid to parse IIF and OIF. A second problem can happen when the user dumps a cache entry where a VIF, that was referenced at creation time, has been removed.

2010-03-27ixgbe: Do not run all Diagnostic offline tests when VFs are activeGreg Rose1-0/+21
When running the offline diagnostic tests check to see if any VFs are online. If so then only run the link test. This is necessary because the VFs running in guest VMs aren't aware of when the PF is taken offline for a diagnostic test. Also put a message to the system log telling the system administrator to take the VFs offline manually if (s)he wants to run a full diagnostic. Return 1 on each of the tests not run to alert the user of the condition.
