7bb7b27fb1 Make sure the mlx4en RX DMA ring gets stamped with software ownership
in order to prevent the flow of QP to error in the firmware once
UPDATE_QP is called.

d4a7f90c0a Use static device numbering instead of dynamic one when creating
mlx4en network interfaces. This prevents infinite unit number growth
typically when the mlx4en driver is used inside virtual machines which
support runtime PCI attach and detach.

5a2866e9b1 Allow communication between functions on the same host when using the
mlx4en(4) driver in SRIOV mode.

Place a copy of the destination MAC address in the send WQE only under
SRIOV/eSwitch configuration or when the device is in selftest. This
allows communication between functions on the same host.

156b40b62b Free hardware queue resource after port is stopped in the mlx4en(4)
driver. Else if the port is up the resource might still be busy and
the MTT free will fail.

791c9d7848 Don't free uninitialized sysctl contexts in the mlx4en driver. This
can cause NULL pointer panics during failed device attach.

97549c34ec Move the ConnectX-3 and ConnectX-2 driver from sys/ofed into sys/dev/mlx4
like other PCI network drivers. The sys/ofed directory is now mainly
reserved for generic infiniband code, with exception of the mthca driver.

- 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 .
