Add some changes from ix-3.2.17.tar.gz and r328265. Not fully synchronized.

Some others (e.g. sfp cage interrupt and bypass adapter  stuff) will be merged
later:

- Initialize firmware command buffer correctly in ixgbe_read_ee_hostif_X550()
  and ixgbe_read_ee_hostif_buffer_X550(). These functions are used when reading
  NVM.
- Fix a bug that ixgbe_mng_present() misunderstand management capability on
  X550 and newer on some environment. X550 changed FWSM bit definition.
  See X540 document and X550's document and compare them.
- Fix checksum calculation in ixgbe_set_fw_drv_ver_generic(). This function is
  not used in NetBSD.
- Add some unused funtions.
- Whitespace fix.
- Check offset correctly in ixgbe_get_oem_prod_version(). Note that this
  function is not used.
- Set PHY correctly in ixgbe_setup_mac_link_sfp_x550a() if a device is a
  C3000 KR SFP+.

Fix race about writing adapter->link_active for ixg(4).
adapter->link_active is updated by ixgbe_update_link_status() only.

The function is called from the following four functions.
    - ixgbe_media_status()
    - ixgbe_local_timer1()
    - ixgbe_stop()
    - ixgbe_handle_link()

The functions other than ixgbe_handle_link() call ixgbe_update_link_status()
with holding IXGBE_CORE_LOCK, however ixgbe_handle_link() calls it without
holding IXGBE_CORE_LOCK. That can cause race. So, add IXGBE_CORE_LOCK to
ixgbe_handle_link().

Tested by msaitoh@n.o and me.

Fix race about writing adapter->link_active for ixv(4).
adapter->link_active is updated by ixv_update_link_status() only.

The function is called from the following two functions.
    - ixv_media_status()
    - ixv_handle_link()

ixv_media_status() calls ixv_update_link_status() with holding
IXGBE_CORE_LOCK, however ixv_handle_link() calls it without
holding IXGBE_CORE_LOCK, the same as ixg(4).

ok by msaitoh@n.o.

- Add link related softint's counter.
- Fix indent.
