21f569af9a mwifiex: initiate card-specific work atomically
The non-atomic test + set is a little awkward here, and it technically
means we might double-schedule work unnecessarily. AFAICT, this is not
really a problem, since the extra "work" will be a no-op (the flag(s)
will be cleared by then), but it's still an anti-pattern.

Rewrite this to use the atomic test_and_set_bit() helper instead.

b18e5e86b4 ldmvsw: unregistering netdev before disable hardware
When running LDom binding/unbinding test, kernel may panic
in ldmvsw_open(). It is more likely that because we're removing
the ldc connection before unregistering the netdev in vsw_port_remove(),
we set up a window of time where one process could be removing the
device while another trying to UP the device. This also sometimes causes
vio handshake error due to opening a device without closing it completely.
We should unregister the netdev before we disable the "hardware".

8c977f5a85 mdio: mux: fix device_node_continue.cocci warnings
Device node iterators put the previous value of the index variable, so an
explicit put causes a double put.

In particular, of_mdiobus_register can fail before doing anything
interesting, so one could view it as a no-op from the reference count
point of view.

70957eaecc macvlan: Fix performance issues with vlan tagged packets
Macvlan always turns on offload features that have sofware
fallback (NETIF_GSO_SOFTWARE).  This allows much higher guest-guest
communications over macvtap.

However, macvtap does not turn on these features for vlan tagged traffic.
As a result, depending on the HW that mactap is configured on, the
performance of guest-guest communication over a vlan is very
inconsistent.  If the HW supports TSO/UFO over vlans, then the
performance will be fine.  If not, the the performance will suffer
greatly since the VM may continue using TSO/UFO, and will force the host
segment the traffic and possibly overlow the macvtap queue.

This patch adds the always on offloads to vlan_features.  This
makes sure that any vlan tagged traffic between 2 guest will not
be segmented needlessly.

66c25f6e31 net: stmmac: use correct pointer when printing normal descriptor ring
There are two pointers in sysfs_display_ring,
one that increments if using normal dma descriptors,
another if using extended dma descriptors.

When printing the normal dma descriptors, the wrong pointer is used,
thus the printed descriptor addresses are incorrect.
