Log Message:
Pull up the following, requested by msaitoh in ticket #1933:

        sys/dev/pci/ixgbe/ix_txrx.c                     1.105-1.116 via patch
        sys/dev/pci/ixgbe/ixgbe.c                       1.345-1.346,1.349 via patch
        sys/dev/pci/ixgbe/ixgbe.h                       1.94-1.98
        sys/dev/pci/ixgbe/ixgbe_type.h                  1.62
        sys/dev/pci/ixgbe/ixv.c                         1.193,1.195-1.196

- Clear the WTHRESH bit field before writing it.
- Optimize ixgbe_txeof().
- Use kmem_zalloc() instead of malloc(,M_ZERO).
- Add QPRDC(Queue Packet Receive Drop Count) into iqdrops.
- No functional change
  - Move assignment of TXD.
  - ixv(4): Remove unused IFF_OACTIVE.
  - Don't include the Flow Director related members to reduce the
    size of struct tx_ring. On amd64 and aarch64, the real size is
    not changed because of the alignment.
  - The descriptor ring size and the alignment are tested in the
    attach function, so it's not required to use
    roundup2(size, DBA_ALIGN).
  - Use #ifdef LRO more to reduce the size of struct rx_ring.
  - Change "me" from 32bit to 8bit because the max is 128.
    This commit doesn't change the real size of ix_queue, tx_ring
    and rx_ring because of the alignment.
  - Th RSC (hardware receive side coalescing) feature has been
    disabled all along, so enclose the code with #ifdef RSC.
  - Remove unused.
  - Modify for the readability.
  - Modify comment.
  - Fix comment. Whitespace.
