There are some '%u' for 'int' and '%d' for 'unsigend int', they should be
fixed.

2. Removed unnecessary prints around memory allocation failure
which are not required, as reported by the checkpatch script.

IB/core: Set correct payload length for RoCEv2 over IPv6

For GSI QP traffic, the count of the udp header bytes was missing from
the IPv6 header, fix that.

IB/mlx4: Enable send of RoCE QP1 packets with IP/UDP headers

RoCEv2 packets are sent over IP/UDP protocols.
The mlx4 driver uses a type of RAW QP to send packets for QP1 and
therefore needs to build the network headers below BTH in software.

This patch adds option to build QP1 packets with IP and UDP headers if
RoCEv2 is requested.

IB/core: Initialize UD header structure with IP and UDP headers

ib_ud_header_init() is used to format InfiniBand headers
in a buffer up to (but not with) BTH. For RoCE UDP ENCAP it is
required that this function would be able to build also IP and UDP
headers.

infiniband: add in export.h for files using EXPORT_SYMBOL/THIS_MODULE

These were getting it implicitly via device.h --> module.h but
we are going to stop that when we clean up the headers.

Fix these in advance so the tree remains biscect-clean.

IB/core: Add VLAN support for IBoE

Add 802.1q VLAN support to IBoE. The VLAN tag is encoded within the
GID derived from a link local address in the following way:

GID[11] GID[12] contain the VLAN ID when the GID contains a VLAN.

The 3 bits user priority field of the packets are identical to the 3
bits of the SL.

In case of rdma_cm apps, the TOS field is used to generate the SL
field by doing a shift right of 5 bits effectively taking to 3 MS bits
of the TOS field.

IB/core: Fix and clean up ib_ud_header_init()

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.

Linux-2.6.12-rc2

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
