While doing the work on igb I realized there were a few cases where we were
still adding VLANs to the VLVF entries for the PF when they were not
needed.  This patch cleans that up so that the only time we add a PF entry
to the VLVF is either for VLAN 0 or if the PF has requested a VLAN that a VF
is already using.

Lock is taken from ixgbe_low_latency_recv, and there under this
lock we use ixgbe_clean_rx_irq so it looks wrong for me to increment

====================
Enhance stmmac driver to support GMAC4.x IP

This is a subset of patch to enhance current stmmac driver to support
new GMAC4.x chips. New set of callbacks is defined to support this new
family: descriptors, dma, core.

One of main changes of GMAC 4.xx IP is descriptors management.
 -descriptors are only used in ring mode.
 -A descriptor is composed of 4 32bits registers (no more extended
  descriptors)
 -descriptor mechanism (Tx for example, but it is exactly the same for RX):
 -useful registers:
  -DMA_CH#_TxDesc_Ring_Len: length of transmit descriptor ring
  -DMA_CH#_TxDesc_List_Address: start address of the ring
  -DMA_CH#_TxDesc_Tail_Pointer: address of the last descriptor to send + 1.
  -DMA_CH#_TxDesc_Current_App_TxDesc: address of the current descriptor

 -The descriptor Tail Pointer register contains the pointer to the
  descriptor address (N). The base address and the current
  descriptor decide the address of the current descriptor that the
  DMA can process. The descriptors up to one location less than the
  one indicated by the descriptor tail pointer (N-1) are owned by
  the DMA. The DMA continues to process the descriptors until the
  following condition occurs:
  "current descriptor pointer == Descriptor Tail pointer"

  Then the DMA goes into suspend mode. The application must perform
  a write to descriptor tail pointer register and update the tail
  pointer to have the following condition and to start a new transfer:
  "current descriptor pointer < Descriptor tail pointer"

  The DMA automatically wraps around the base address when the end
  of ring is reached.

New features are available on IP:
 -TSO (TCP Segmentation Offload) for TX only
 -Split header: to have header and payload in 2 different buffers (not yet implemented)

Below some throughput figures obtained on some boxes:

                        iperf (mbps)
--------------------------------------
                       tcp     udp
                    tx   rx   tx  rx
                     -----------------
    GMAC4.x         935  930  750 800

Note: There is a change in 4.10a databook on bitfield mapping of DMA_CHANx_INTR_ENA register.
This requires to have é diffrent set of callbacks between IP 4.00a and 4.10a.

For non-SACK connections, cwnd is lowered to inflight plus 3 packets
when the recovery ends. This is an optional feature in the NewReno
RFC 2582 to reduce the potential burst when cwnd is "re-opened"
after recovery and inflight is low.

This feature is questionably effective because of PRR: when
the recovery ends (i.e., snd_una == high_seq) NewReno holds the
CA_Recovery state for another round trip to prevent false fast
retransmits. But if the inflight is low, PRR will overwrite the
moderated cwnd in tcp_cwnd_reduction() later regardlessly. So if a
receiver responds bogus ACKs (i.e., acking future data) to speed up
transfer after recovery, it can only induce a burst up to a window
worth of data packets by acking up to SND.NXT. A restart from (short)
idle or receiving streched ACKs can both cause such bursts as well.

On the other hand, if the recovery ends because the sender
detects the losses were spurious (e.g., reordering). This feature
unconditionally lowers a reverted cwnd even though nothing
was lost.

By principle loss recovery module should not update cwnd. Further
pacing is much more effective to reduce burst. Hence this patch
removes the cwnd moderation feature.

Newer Fedora and OpenSUSE didn't boot with my standard configuration.
It took me some time to figure out why, in fact I had to write a script
to try different config options systematically.

The problem is that something (systemd) in dracut depends on
CONFIG_FHANDLE, which adds open by file handle syscalls.

While it is set in defconfigs it is very easy to miss when updating
older configs because it is not default y.

Make it default y and also depend on EXPERT, as dracut use is likely
widespread.

The recently introduced batched invalidations mechanism uses its own
mechanism for shootdown.  However, it does wrong accounting of
interrupts (e.g., inc_irq_stat is called for local invalidations),
trace-points (e.g., TLB_REMOTE_SHOOTDOWN for local invalidations) and
may break some platforms as it bypasses the invalidation mechanisms of
Xen and SGI UV.

This patch reuses the existing TLB flushing mechnaisms instead.  We use
NULL as mm to indicate a global invalidation is required.
