- Use MCLGET() instead of homegrown cluster (jcl) allocation mechanism.
  Before this commit, resource shortage was easily occurred because
  the total number of the clusters is small.
- Improve performance:
  - Use m_adj(ETHER_ALIGN) more.
  - Sprinkle __predict_false() in the RX path.
  - Don't pre-allocate a cluster for RXCOPY case to improve short
    packet's performance.
- Call bus_dmamap_unload(9) via ixgbe_dmamap_unload(), before freeing
  DMA buffer. Also, when the buffer is already freed, do not call
  bus_dmamap_unload(9) (no resource leaks with this change). This
  change is required to make ixg(4) work on alpha.
- Keep m_len and m_pkthdr.len consistent to prevent panic on arm.
- Fix panic when bus_dmamap_load_mbuf() failed in
  ixgbe_setup_receive_ring().
- Added BUS_DMA_COHERENT flag to bus_dmamem_map() to improve stability
  on aarch64.
- Use uint64_t instead of bus_addr_t for the TX descriptor's buffer
  address. At least, this change is required for macppc
  (sizeof(bus_addr_t) == 4) to make TX work.
- Fix little-endian dependence.
- Set rxr->next_to_refresh correctly in ixgbe_setup_receive_ring().
- Refresh unrefreshed descriptors' buffers correctly.
- Don't call bus_dmamap_sync with rx_mbuf_sz(== MCLBYTES) to prevent
  panic.
- Save the discard_multidesc state to not to forget the state by
  exiting rxeof().
- Add missing increment of no_mbuf error counter.
- Don't increment no_mbuf evcnt(9) when discarding multi-descriptor
  packet.
- ixv: Modify error message to sync with ixgbe.c
- Print the error value of ixgbe_reset_hw() for debugging.
- Remove extra unlock/lock processing around if_percpuq_enqueue().
- Refactor rxr->next_to_check updating.
- Add new sysctl "rx_copy_len".
- Add a new sysctl to read rxr->next_to_refresh.
- Print error number when error occurred.
- Rename ix{gbe,v}_stop() with ix{gbe,v}_stop_locked(). No functional
  change.
- Don't use fixed value.
- Comment out flow director processing in fast path.
- Add missing NetBSD RCS IDs and __KERNEL_RCSID()s.
- KNF.
- Fix typos.
