Change abbreviated IB_QPT_RAW_ETY to IB_QPT_RAW_ETHERTYPE to make
the special QP type easier to understand.

Add a new parameter to ib_register_device() so that low-level device
drivers can pass in a pointer to a callback function that will be
called for each port that is registered in sysfs.  This allows
low-level device drivers to create files in

    /sys/class/infiniband/<hca>/ports/<N>/

without having to poke through the internals of the RDMA sysfs handling.

There is no need for an unregister function since the kobject
reference will go to zero when ib_unregister_device() is called.

 - Add new IB_WR_MASKED_ATOMIC_CMP_AND_SWP and IB_WR_MASKED_ATOMIC_FETCH_AND_ADD
   send opcodes that can be used to post "masked atomic compare and
   swap" and "masked atomic fetch and add" work request respectively.
 - Add masked_atomic_cap capability.
 - Add mask fields to atomic struct of ib_send_wr
 - Add new opcodes to ib_wc_opcode

The new operations are described more precisely below:

* Masked Compare and Swap (MskCmpSwap)

The MskCmpSwap atomic operation is an extension to the CmpSwap
operation defined in the IB spec.  MskCmpSwap allows the user to
select a portion of the 64 bit target data for the “compare” check as
well as to restrict the swap to a (possibly different) portion.  The
pseudo code below describes the operation:

| atomic_response = *va
| if (!((compare_add ^ *va) & compare_add_mask)) then
|     *va = (*va & ~(swap_mask)) | (swap & swap_mask)
|
| return atomic_response

The additional operands are carried in the Extended Transport Header.
Atomic response generation and packet format for MskCmpSwap is as for
standard IB Atomic operations.

* Masked Fetch and Add (MFetchAdd)

The MFetchAdd Atomic operation extends the functionality of the
standard IB FetchAdd by allowing the user to split the target into
multiple fields of selectable length. The atomic add is done
independently on each one of this fields. A bit set in the
field_boundary parameter specifies the field boundaries. The pseudo
code below describes the operation:

| bit_adder(ci, b1, b2, *co)
| {
|	value = ci + b1 + b2
|	*co = !!(value & 2)
|
|	return value & 1
| }
|
| #define MASK_IS_SET(mask, attr)      (!!((mask)&(attr)))
| bit_position = 1
| carry = 0
| atomic_response = 0
|
| for i = 0 to 63
| {
|         if ( i != 0 )
|                 bit_position =  bit_position << 1
|
|         bit_add_res = bit_adder(carry, MASK_IS_SET(*va, bit_position),
|                                 MASK_IS_SET(compare_add, bit_position), &new_carry)
|         if (bit_add_res)
|                 atomic_response |= bit_position
|
|         carry = ((new_carry) && (!MASK_IS_SET(compare_add_mask, bit_position)))
| }
|
| return atomic_response

ib_ud_header_init() first clears header and then fills up the various
fields.  Later on, it tests header->immediate_present, which it has
already cleared, so the condition is always false.  Fix this by adding
an immediate_present parameter and setting header->immediate_present
as is done with grh_present.  Also remove unused calculation of
header_len.

The defined SCTP number is incorrect (0x83, rather than 0x84), and
since it is not used anywhere, simply remove the definition.
