7b00a204bb bond: fix vlan flag interpretation
This patch contains a fix for link bonding handling of vlan tagged packets in mode 3 and 5.
Currently xmit_slave_hash function misinterprets the PKT_RX_VLAN_PKT flag to mean that
there is a vlan tag within the packet when in actually means that there is a valid entry
in the vlan_tci field in the mbuf.

- Fixed VLAN tag support in hashing functions.
- Adds support for TCP in layer 4 header hashing.
- Splits transmit hashing function into separate functions for each policy to
  reduce branching and to make the code clearer.
- Fixed incorrect flag set in test application packet generator.

494a1f991e ixgbevf: fix link state
This patch fixes checking the link state of a virtual function. If the
state has already been checked, it does not need to be checked
again. Previously, get_link_status in the ixgbe_hw struct was used to
track if the information had already been retrieved, but this field
was always set to false (signifying that the information was
up-to-date). The problem was introduced by commit 8ef32003 which was
part of a patch set to update the ixgbe portion of the PMD. This patch
does not break consistency with the ixgbevf driver. Instead, it fixes
the problem at the level of DPDK.

Applications that rely on the reported link speed could fail without
this patch. The qos_sched example application provided with DPDK did
not run when virtual functions were used. The output for this example
application is shown below:

EAL: Error - exiting with code: 1
  Cause: Unable to config sched subport 0, err=-2

The problem and the effect of the patch can been seen by running the
l2fwd example application using the following command:

sudo ./build/l2fwd -c 0x3 -n 4 -- -p 0x3 -T 0

Before the patch has been applied (with both links up):
...

Port 0 Link Up - speed 100 Mbps - half-duplex

Port 1 Link Up - speed 100 Mbps - half-duplex

L2FWD: entering main loop on lcore 1

Root cause is test app on primary process only starts device, but

So the tx queue is still NULL when secondary process startup.

190a61b14c kni: fix build with kernel < 2.6.35 and vhost debug enabled
Seen on RHEL-6.5:
lib/librte_eal/linuxapp/kni/kni_vhost.c:222:

lib/librte_eal/linuxapp/kni/kni_vhost.c:313:

	but argument is of type ‘int’
lib/librte_eal/linuxapp/kni/kni_vhost.c:580:
	error: assignment makes pointer from integer without a cast

RHEL6.5 kernel is based on 2.6.32. But there are two changing
from 2.6.35:
1. socket struct is changed
It wrappered previous wait_queue_head_t of socket to
struct socket_wq. So for the kernel older than 2.6.35, we should
directly use socket->wait instead.

2. new function sk_sleep()
This function is implemented from 2.6.35 to obtain wait queue
from struct sock. This patch adds a macro in kni/compat.h
to be compatible with older kernels.

Patch is tested in RHEL6.5 and RHEL7.0 with:
CONFIG_RTE_LIBRTE_KNI=y
CONFIG_RTE_KNI_KO_DEBUG=y

46bc9d7513 ixgbe: fix multi-process support
When using multiple processes, the TX function used in all processes
should be the same, otherwise the secondary processes cannot transmit
more than tx-ring-size - 1 packets.
To achieve this, we extract out the code to select the ixgbe TX function
to be used into a separate function inside the ixgbe driver, and call
that from a secondary process when it is attaching to an
already-configured NIC.

Testing with symmetric MP app shows that we are able to RX and TX from
both primary and secondary processes once this patch is applied.

199e6b913e ixgbe: fix array overflow in vector Rx
Switch the order of the conditions in a while loop, so we check the
range of "i" against the max, before using it to index into the array.

0d6e2d783d igb_uio: fix build with kernel 3.18
This patch fixes build failing with undefined symbol _PAGE_IOMAP with
kernel 3.18.

The Xen-specific _PAGE_IOMAP PTE flag was removed in kernel 3.18 and
could be used for other purpose in future. This patch ensures that
_PAGE_IOMAP flag is only used for kernels before 3.18.

b443307ad3 ring: fix return type in enqueue and dequeue burst functions
Enqueue and dequeue burst functions always return a positive
value (including 0), so return type should be unsigned,
instead of int.

Fixed also API doc for one of the functions.

ca68c8190f net: fix IPv6 checksum
For rte_ipv6_phdr_cksum() gcc 4.8.* with "-O3" not always generates
correct code.
Sometimes it 'forgets' to put len and proto fields of psd_header on the stack.
To overcome that problem and speedup things a bit, refactored rte_raw_cksum()
by splitting ipv6 pseudo-header csum calculation into 3 phases:
1. calc sum for src & dst addresses
2. add sum for proto & len.
3. finalise sum
That makes gcc to generate valid code and helps to avoid any copying.

d3e454a86f cfgfile: fix read of empty file
If the file to be read by the cfgfile is empty, i.e. no configuration
data, but possibly comments present, the cfgfile should not mark the
last processed section (curr_section) as having N entries, since there
is no last processed section.

8b27765d67 eal: use safe snprintf to print version
When printing the version string to a local variable, use snprintf for
safety over sprintf. This is general good practice even if the values
to print are all hard-coded.
