mlx4: Map core_clock page to user space only when allowed
Currently when we map the hca_core_clock page to the user space,
there are vulnerable registers, one of which is semaphore, on
this page as well. If user read the wrong offset, it can modify the
above semaphore and hang the device.
Hence, mapping the hca_core_clock page to the user space only when
user required it specifically.
After this patch, mlx4 core_clock won't be mapped to user space by
default. Oppose to current state, where mlx4 core_clock is always mapped
to user space.

mlx4ib and mlx5ib: Set slid to zero in Ethernet completion struct
IB spec says that a lid should be ignored when link layer is Ethernet,
for example when building or parsing a CM request message (CA17-34).
However, since ib_lid_be16() and ib_lid_cpu16() validates the slid,
not only when link layer is IB, we set the slid to zero to prevent
false warnings in the kernel log.

mlx4: replace LinuxKPI macros with ifnet functions
The LinuxKPI net_device actually is an ifnet; in order to further
clean that up so we can extend "net_device" replace the few macros
inline in mlx
