2013-01-03net: remove unnecessary NET_ADDR_RANDOM "bitclean"Jiri Pirko
NET_ADDR_SET is set in dev_set_mac_address() no need to alter dev->addr_assign_type value in drivers. Signed-off-by: Jiri Pirko <jiri@resnulli.us> Signed-off-by: David S. Miller <davem@davemloft.net>

2012-11-28team: fix hw_features setupJiri Pirko
Do this in the same way bonding does. This fixed setup resolves performance issues when using some cards with certain offloading. Signed-off-by: Jiri Pirko <jiri@resnulli.us> Signed-off-by: David S. Miller <davem@davemloft.net>
2012-11-21team: bcast: convert return value of team_dev_queue_xmit() to bool correctlyJiri Pirko
The thing is that team_dev_queue_xmit() returns NET_XMIT_* or -E*. bc_trasmit() should return true in case all went well. So use ! to get correct retval from team_dev_queue_xmit() result. This bug caused iface statistics to be badly computed. This bug was introduced by: team: add broadcast mode (5fc889911a99043a97da1daa0d010ad72cbc3042) Reported-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Jiri Pirko <jiri@resnulli.us> Signed-off-by: David S. Miller <davem@davemloft.net>
2012-10-04team: set qdisc_tx_busylock to avoid LOCKDEP splatEric Dumazet
If a qdisc is installed on a team device, its possible to get a lockdep splat under stress, because nested dev_queue_xmit() can lock busylock a second time (on a different device, so its a false positive) Avoid this problem using a distinct lock_class_key for team devices.

2012-09-27team: fix return value checkWei Yongjun
In case of error, the function genlmsg_put() returns NULL pointer not ERR_PTR(). The IS_ERR() test in the return value check should be replaced with NULL test. dpatch engine is used to auto generate this patch.

2012-09-22team: send port changed when addedJiri Pirko
On some hw, link is not up during adding iface to team. That causes event not being sent to userspace and that may cause confusion. Fix this bug by sending port changed event once it's added to team. Signed-off-by: Jiri Pirko <jiri@resnulli.us> Signed-off-by: David S. Miller <davem@davemloft.net>

2012-09-10netlink: Rename pid to portid to avoid confusionEric W. Biederman
It is a frequent mistake to confuse the netlink port identifier with a process identifier. Try to reduce this confusion by renaming fields that hold port identifiers portid instead of pid. I have carefully avoided changing the structures exported to userspace to avoid changing the userspace API. I have successfully built an allyesconfig kernel with this change. Signed-off-by: "Eric W.

2012-08-24team: don't print warn message on -ESRCH during event sendJiri Pirko

2012-08-20team: add support for non-ethernet devicesJiri Pirko

slave_enable_netpoll() and __netpoll_setup() may be called with read_lock() held, so should use GFP_ATOMIC to allocate memory. Eric suggested to pass gfp flags to __netpoll_setup().

2012-08-03team: add support for queue override by setting queue_id for portJiri Pirko

2012-07-18team: refine IFF_XMIT_DST_RELEASE capabilityJiri Pirko
Cloned patch of Eric Dumazet for bonding. Some workloads greatly benefit of IFF_XMIT_DST_RELEASE capability on output net device, avoiding dirtying dst refcount. team currently disables IFF_XMIT_DST_RELEASE unconditionally. If all ports have the IFF_XMIT_DST_RELEASE bit set, then team dev can also have it in its priv_flags.

2012-06-28net: Use NLMSG_DEFAULT_SIZE in combination with nlmsg_new()Thomas Graf
