mlx4: rename conflicting netdev_priv() to mlx4_netdev_priv()

netdev_priv() is a LinuxKPI function which was used with the old ifnet
linux/netdevice.h implementation which was not adaptable to modern
Linux drviers unless rewriting them for ifnet in first place which
defeats the purpose.
Rename the netdev_priv() calls in mlx4 to mlx4_netdev_priv()
returning the ifnet softc to avoid conflicting symbol names
with different implementations in the future.

mlx4/OFED: replace the struct net_device with struct ifnet

Given all the code does operate on struct ifnet, the last step in this
longer series of changes now is to rename struct net_device to
struct ifnet (that is what it was defined to in the LinuxKPi code).
While mlx4 and OFED are "shared" code the decision was made years ago
to not write it based on the netdevice KPI but the native ifnet KPI
for most of it. This commit simply spells this out and with that
frees "struct netdevice" to be re-done on LinuxKPI to become a more
native/mixed implementation over time as needed by, e.g., wireless
drivers.

Update the mlx4 core and mlx4en(4) modules towards Linux v4.9.

Background:
The coming ibcore update forces an update of mlx4ib(4) which in turn requires
an updated mlx4 core module. This also affects the mlx4en(4) module because
commonly used APIs are updated. This commit is a middle step updating the
mlx4 modules towards the new ibcore.

This change contains no major new features.

Changes in mlx4:
a) Improved error handling when mlx4 PCI devices are
detached inside VMs.
b) Major update of codebase towards Linux 4.9.

Changes in mlx4ib(4):
a) Minimal changes needed in order to compile using the
updated mlx4 core APIs.

Changes in mlx4en(4):
a) Update flow steering code in mlx4en to use new APIs for
registering MAC addresses and IP addresses.
b) Update all statistics counters to be 64-bit.
c) Minimal changes needed in order to compile using the
updated mlx4 core APIs.

Move the ConnectX-3 and ConnectX-2 driver from sys/ofed into sys/dev/mlx4

- Add new manual page, mlx4en(4), describing how to configure and load
mlx4en.

- All relevant driver C-files are now prefixed mlx4, mlx4_en and
mlx4_ib respectivly to avoid object filename collisions when compiling
the kernel. This also fixes an issue with proper dependency file
generation for the C-files in question.

- Device mlxen is now device mlx4en and depends on device mlx4, see
mlx4en(4). Only the network device name remains unchanged.

- The mlx4 and mlx4en modules are now built by default on i386 and
amd64 targets. Only building the mlx4ib module depends on
WITH_OFED=YES .
