Leon Romanovsky 6bf9d8f6f0 RDMA/include: Replace license text with SPDX tags
The header files in RDMA subsystem are dual licensed and can be
described by simple SPDX tag, so replace all of them at once
together with making them use the same coding style for header
guard defines.

Kaike Wan 6d72344cf6 IB/ipoib: Increase ipoib Datagram mode MTU's upper limit
Currently the ipoib UD mtu is restricted to 4K bytes. Remove this
limitation so that the IPOIB module can potentially use an MTU (in UD
mode) that is bounded by the MTU of the underlying device. A field is
added to the ib_port_attr structure to indicate the maximum physical
MTU the underlying device supports.

Erez Alfasi 19b1a294b0 RDMA: Use __packed annotation instead of __attribute__ ((packed))
"__attribute__" set of macros has been standardized, have became more
potentially portable and consistent code back in v2.6.21 by commit
82ddcb040 ("[PATCH] extend the set of "__attribute__" shortcut macros").
Moreover, nowadays checkpatch.pl warns about using __attribute__((packed))
instead of __packed.

This patch converts all the "__attribute__ ((packed))" annotations to
"__packed" within the RDMA subsystem.

Vishwanathapura, Niranjana 2280740f01 IB/hfi1: Virtual Network Interface Controller (VNIC) HW support
HFI1 HW specific support for VNIC functionality.
Dynamically allocate a set of contexts for VNIC when the first vnic
port is instantiated. Allocate VNIC contexts from user contexts pool
and return them back to the same pool while freeing up. Set aside
enough MSI-X interrupts for VNIC contexts and assign them when the
contexts are allocated. On the receive side, use an RSM rule to
spread TCP/UDP streams among VNIC contexts.

Dennis Dalessandro d4ab347005 IB/core: Add core header changes needed for OPA
This patch adds the value of the CNP opcode to the existing list of enumerated
opcodes in ib_pack.h

Add common OPA header definitions for driver
build:
- opa_port_info.h
- opa_smi.h
- hfi1_user.h

Additionally, ib_mad.h, has additional definitions
that are common to ib_drivers including:
- trap support
- cca support

The qib driver has the duplication removed in favor
those in ib_mad.h
