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 on 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 Use netdev_alloc_skb_ip_align() instead of aligning with skb_reserve().
o Other minor code clean up.
