8bd6c395a5 examples/vhost: increase maximum queue number
Increase MAX_QUEUES from 256 to 512.

In vhost example, MAX_QUEUES macro should be the maximum possible queue number of the port.
Theoretically we should only set up the queues that are used, i.e., first rx queue of each pool, or
at most queues from 0 to MAX_QUEUES. Before we revise the implementation and are certain all NICs support
this well, add a remind message to user.

f2ef6f21ee bond: fix mac assignment to slaves
Adding call to mac_address_slaves_update from the lsc handler when the
first slave become active to propagate any mac changes made while
devices are inactive

Changed removing slave logic to use memmove instead of memcpy to move
data within the same array, as this was corrupting the slave array.

Adding unit test to cover failing assignment scenarios

81ab433fff igb_uio: fix build with long term kernel and RHEL
Function pci_num_vf() is introduced from upstream linux-2.6.34. So
this patch make compatible with longterm kernel linux-2.6.32.63.

For RHEL, function pci_num_vf() begins from RHEL5 update9. And
it is stub-defined when CONFIG_PCI_IOV is not enabled.

So dropped the CONFIG_PCI_IOV checking of commit 11ba0426.

For other distro like RHEL behaved to pci_num_vf(), we could simply
append following condition macro:
(!(defined(OTHER_RELEASE_CODE) && \
 OTHER_RELEASE_CODE >= OTHER_RELEASE_VERSION(X, Y)))

        does break strict-aliasing rules

The root cause is that, compile enable strict aliasing by default,
while in function rte_raw_cksum() try to convert 'const char *'
to 'const uint16_t *'.

This workaround is to solve the compile issue of GCC strict-aliasing (two
different type pointers should not be point to the same memory address).

For GCC 4.4.7 it will definitely occurs if  flags "-fstrict-aliasing"

3a52e64742 lib: fix cache alignment of structures
Include rte_memory.h for lib files that use __rte_cache_aligned
attribute.

Consider the following code:

	struct per_core_foo {
		...
	} __rte_cache_aligned;

	struct global_foo {
		struct per_core_foo foo[RTE_MAX_CORE];
	};

If __rte_cache_aligned is not defined (rte_memory.h is not included),
the code compiles but the structure is not aligned... it defines the
structure and creates a global variable called __rte_cache_aligned.
And this can lead to really bad things if this code is in a .h that
is included by files that may or may not include rte_memory.h

In order to achieve this, while still keeping the document readable, the
chapter on system requirements has been moved to instead be a section
within the chapter on compiling the DPDK outside of the ports
collection. This move is necessary, since it covered a lot of detail on
installing other ports required to build DPDK. These steps are not

The symmetric_mp example app is set up to allow two processes to
share a NIC port, with each pulling packets from one queue. In order
to have the app continue working when one of the process dies, the
drop_en bit should be set in the NIC configuration. Without this bit
set, the NIC will stall once any queue fills. With the bit set, once
a queue fills, all subsequent packets for that queue are discarded
allowing other queues to continue operating as normal.

So we need to try different checks.
Previous trials were done in testpmd (see commits
51f694dd40f56 and 64741f237cf29) without full success.
This one is not guaranteed to work everywhere so it could
evolve when exceptions are found.

If endianness is not detected, there is a fallback on x86
to little endian. It could be forced before doing detection
but it would add some arch-dependent code in the generic header.

The option CONFIG_RTE_ARCH_BIG_ENDIAN introduced for IBM Power only
(commit a982ec81d84d53) can be removed. A compile-time check is better.

aaa662e75c cmdline: fix overflow on bsd
When using test-pmd with flow director in FreeBSD, the application will
segfault/Bus error while parsing the command-line. This is due to how
each commands result structure is represented during parsing, where the offsets
for each tokens value is stored in a character array(char result_buf[BUFSIZ])
in cmdline_parse()(./lib/librte_cmdline/cmdline_parse.c).

The overflow occurs where BUFSIZ is less than the size of a commands result
structure, in this case "struct cmd_pkt_filter_result"
(app/test-pmd/cmdline.c) is 1088 bytes and BUFSIZ on FreeBSD is 1024 bytes as
opposed to 8192 bytes on Linux.

The problem can be reproduced by running test-pmd on FreeBSD:
./testpmd -c 0x3 -n 4 -- -i --portmask=0x3 --pkt-filter-mode=perfect
And adding a filter:
add_perfect_filter 0 udp src 192.168.0.0 1024 dst 192.168.0.0 1024 flexbytes
0x800 vlan 0 queue 0 soft 0x17

This patch removes the OS dependency on BUFSIZ and defines and uses a
library #define CMDLINE_PARSE_RESULT_BUFSIZE 8192

Added boundary checking to ensure this buffer size cannot overflow, with
an error message being produced.

b70ae1899f enic: fix warnings
A lot of warnings were not seen because $(WERROR_FLAGS) was not set
in the Makefile. But they appear with toolchains that enforce more checks.

-Wno-deprecated seems useless.
-Wno-strict-aliasing is added to avoid false positives.

This patch cleans up unused variable, unused functions, wrong types,
static declarations, etc. A lot of functions have unused parameters;
it suggests that more clean-up could be needed.

8436acd6ba kni: fix build on IBM Power
Because of different cache line size, the alignment of struct
rte_kni_mbuf in rte_kni_common.h doesn't work on IBM Power. This patch
changed from 64 to RTE_CACHE_LINE_SIZE micro to do the alignment.

999284fcc3 kni: create interface in current network namespace
With this patch, KNI interface (e.g. vEth0) is created in the
network namespace where the DPDK application is running.
Otherwise, all interfaces are created in the default namespace
in the host.

put_net() is required, since get_net_ns_by_pid() increments
the reference counter of the network namespace with get_net().

2f423f6385 i40e: fix build with 16-byte descriptors
The compile error will occur as below when set 'RTE_LIBRTE_I40E_16BYTE_RX_DESC=y'.
'fd_id' should be used to replace 'fd', as 'fd' is not defined in that structure
at all. In addition, local variable of 'flexbl' and 'flexbh' must be used only if
32 bytes RX descriptor is selected.
