When operating in switchdev mode or using devlink to disable RoCE
only raw Ethernet QPs are allowed to be created.
When in switchdev mode this can lead to passing an invalid port number
as part of the modify qp firmware cmd and will lead to a syndrome
reported back to the user, such as:
* mlx5_cmd_check:803:(pid 50148): RST2INIT_QP(0x502) op_mod(0x0) failed,
status bad parameter(0x3), syndrome (0x177405).
Internal UD QP might be used to test for write combining support (even if
externally we report RoCE as disabled) check for that specific flag and
allow is specifically.

The MTT (Memory Translate Table) interface is no longer used to configure
the buffer address to BT (Base Address Table) that requires driver
mapping. Because the MTT is not compatible with multi-hop addressing of
the hip08, it is replaced by MTR (Memory Translate Region) interface, and
all the MTT functions should be removed.

The patch sets the lag tx affinity of the data QPs and the GSI QPs
according to the LAG xmit slave.
For GSI QPs, in case the link layer is Ethenet (RoCE) we create two GSI
QPs, one for each physical port. When the driver selects the GSI QP, it
will consider the port affinity result. For connected QPs, the driver
sets the affinity of the xmit slave.
The above, ensures that RC QP and it's corresponding GSI QP will transmit
from the same physical port.

Leon Romanovsky says:
====================
This is first part of series which tries to return some sanity to
mlx5_ib_create_qp() function. Such refactoring is required to make
extension of that function with less worries of breaking driver.
Extra goal of such refactoring is to ensure that QP is allocated at the
beginning of function and released at the end. It will allow us to move QP
allocation to be under IB/core responsibility.

In similar way to wqe_sig, the scat_cqe was treated differently from
other create QP vendor flags. Change it to be similar to other flags
and use flags_en mechanism.

MLX5_QP_FLAG_SIGNATURE is exposed to the users but in the kernel
the create_qp flow treated it differently from other MLX5_QP_FLAG_*s.
Fix it by ditching wq_sig boolean variable and use general flag_en
mechanism.

create_flags is checked in too many places and scattered across all
the code, consolidate all the checks inside one function, so we will
be easily see the flow. As part of such change, delete unreachable code,
because IB/core is responsible sanitize the input.
