2012-09-27team: fix return value checkWei Yongjun1-6/+6
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 Pirko1-8/+24
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>
2012-08-14netpoll: use GFP_ATOMIC in slave_enable_netpoll() and __netpoll_setup()Amerigo Wang1-7/+9
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().

2012-07-18team: refine IFF_XMIT_DST_RELEASE capabilityJiri Pirko1-0/+5
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 Graf1-4/+4
Using NLMSG_GOODSIZE results in multiple pages being used as nlmsg_new() will automatically add the size of the netlink header to the payload thus exceeding the page limit. NLMSG_DEFAULT_SIZE takes this into account.

2012-04-21team: allow to enable/disable portsJiri Pirko3-18/+37
This patch changes content of hashlist (used to get port struct by computed index (0...en_port_count-1)). Now the hash list contains only enabled ports so userspace will be able to say what ports can be used for tx/rx. This becomes handy when userspace will need to disable ports which does not belong to active aggregator. By default, newly added port is enabled.
