====================
net: ethernet: aquantia: Add AQtion 2.5/5 GB NIC driver

This series introduces the AQtion NIC driver for the aQuantia
AQC107/AQC108 network devices.

v1: Initial version
v2: o Make necessary drivers/net/ethernet changes to integrate software
    o Drop intermediate atlantic directory
    o Remove Makefile things only appropriate to out of tree module
      building
v3: o Move changes to drivers/net/ethernet/{Kconfig,Makefile} to the last
      patch to ensure clean bisection.
    o Removed inline attribute aq_hw_write_req() as it was defined in
      only one .c file.
    o #included pci.h in aq_common.h to get struct pci definition.
    o Modified code to unlock based execution flow rather than using a
      flag.
    o Made a number of functions that were only used in a single file
      static.
    o Cleaned up error and return code handling in various places.
    o Remove AQ_CFG_IP_ALIGN definition.
    o Other minor code clean up.
v4: o Using do_div for 64 bit division.
    o Modified NIC statistics code.
    o Using build_skb instead netdev_alloc_skb for single fragment packets.
    o Removed extra aq_nic.o from Makefile
v5: o Removed extra newline at the end of the files.
v6: o Removed unnecessary cast from void*.
    o Reworked strings array for ethtool statistics.
    o Added stringset == ETH_SS_STATS checking.
    o AQ_OBJ_HEADER replaced to aq_obj_header_s struct.
    o AQ_OBJ_SET/TST/CLR macroses replaced to inline functions.
    o Driver sources placed in to atlantic directory.
    o Fixed compilation warnings (Make W=1)
    o Added firmware version checking.
    o Code cleaning.
v7  o Removed unnecessary cast from memory allocation function (aq_ring.c).
v8  o Switched to using kcalloc instead kzalloc.
    o Now provide bus_info for ethtool
    o Used div() to avoid __bad_udelay build error.
