namespace for nf_conntrack_reasm code, this prepares

In netpoll tx path, we miss the chance of calling ->ndo_select_queue(),
thus could cause problems when bonding is involved.

This patch makes dev_pick_tx() extern (and rename it to netdev_pick_tx())
to let netpoll call it in netpoll_send_skb_on_dev().

When building 64-bit kernel with this driver we get following warnings from
the compiler:

drivers/net/ethernet/i825xx/znet.c: In function ‘hardware_init’:
drivers/net/ethernet/i825xx/znet.c:863:29: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast]

Instead of forcing device drivers to provide empty ethtool_ops or tweak

When moving a nic from net namespace A to net namespace B,

dev_queue_xmit_nit() should be called right before ndo_start_xmit()
calls or we might give wrong packet contents to taps users :

Packet checksum can be changed, or packet can be linearized or
segmented, and segments partially sent for the later case.

Also a memory allocation can fail and packet never really hit the

In rare circumstances, it's possible a descriptor writeback will occur
before a timestamped Tx packet will go out on the wire, leading to the
driver believing the hardware failed to timestamp the packet. Schedule a
work item for 82576 and use the available time sync interrupt registers
on 82580 and above to account for this.

The PF was not correctly registering any of its VLANs.  As a result any
VLAN tagged traffic from the VF would not be delivered to the PF because
the VLAN was never assigned to the PF pool.

In addition the VF was not allowed to receive traffic from VLAN 0 if it was
allowed to receive untagged frames.  This change corrects that so that it
will correctly receive traffic from VLAN 0.

Pull GFS2 fixes from Steven Whitehouse:
 "Here are three GFS2 fixes for the current kernel tree.  These are all
  related to the block reservation code which was added at the merge
  window.  That code will be getting an update at the forthcoming merge
  window too.  In the mean time though there are a few smaller issues
  which should be fixed.

  The first patch resolves an issue with write sizes of greater than 32
  bits with the size hinting code.  The second ensures that the
  allocation data structure is initialised when using xattrs and the
  third takes into account allocations which may have been made by other
  nodes which affect a reservation on the local node."
