3ed7147189 team: fix hw_features setup
Do this in the same way bonding does. This fixed setup resolves performance
issues when using some cards with certain offloading.

403f43c937 team: bcast: convert return value of team_dev_queue_xmit() to bool correctly
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 (5fc889911a)

b3c581d5d7 team: set qdisc_tx_busylock to avoid LOCKDEP splat
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.

a326e6dd31 team: fix return value check

not ERR_PTR(). The IS_ERR() test in the return value check should
be replaced with NULL test.

15e473046c netlink: Rename pid to portid to avoid confusion
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.

dc9059512c team: refine IFF_XMIT_DST_RELEASE capability
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.
