5e4937a088 app/testpmd: limit port mask bits to configured maximum
The port mask parsing in testpmd allowed up to 64 bits to be processed,
even if RTE_MAX_ETHPORTS is set to a max of 32. Fix this by only
processing up to min(RTE_MAX_ETHPORTS,64) bits of the mask.

c7ba32604d vmxnet3: fix default Tx configuration
Since commit fbde27f19a "get default Rx/Tx configuration from dev info",
a default RX/TX configuration can be used for all PMDs.
In case of vmxnet3, the whole structure was zeroed and not filled out.
The PMD does not support multi segments or offload functions,
so txq_flags should have those flags set.

973273c7a4 i40e: workaround for X710 performance
On X710, performance number is far from the expectation on recent
firmware versions. The fix for this issue may not be integrated in
the following firmware version. So the workaround in software driver
is needed. It needs to modify the initial values of 3 internal only
registers. Note that the workaround can be removed when it is fixed
in firmware in the future.

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.

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.

eced116610 mk: fix build with shared pcap pmd
Some applications doesn't have the pcap link flag
when shared libraries are enabled.
Indeed in such case, pcap PMD must not be linked but pcap library should.

Actually -lpcap is always needed if pcap PMD is used,
and -lrte_pmd_pcap must be set only with static PMD library.
So the flags -lrte_pmd_pcap and -lpcap are enabled separately.

Workarounds in test-pmd/ and test-pipeline/ can be removed.

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

fdef8f927f i40e: fix vlan filtering
">> 5" rather than ">> 4"

vlan id is a 12 bit value.
VFTA is 128 x 32 bit array (128 double word array) which could store 2^12 vlan bits.
Each bit represents whether corresponding vlan tag is set in the VSI.
Use high 7 bits as the index for the double word array.

51e16682cf ixgbe: do not override buffer length
The template mbuf_initializer is hard coded with a buflen which
might have been set differently by the application at the time of
mbuf pool creation.

- move buf_len fields out of rearm_data marker.
- make ixgbe_recv_pkts_vec() not touch buf_len field at all
(as all other RX functions behave).

dc018ce69b enic: fix uninitialized variable
The variable notify_pa is only initialized inside one branch of
an if statement, triggering a compiler error with clang 3.3 on FreeBSD.

  CC vnic/vnic_dev.o
lib/librte_pmd_enic/vnic/vnic_dev.c:777:6: fatal error: variable 'notify_pa'
      is used uninitialized whenever 'if' condition is false [-Wsometimes-uninitialized]
        if (!vnic_dev_in_reset(vdev)) {

Fix this issue by adding "= 0" to the variable definition.

06554d0240 enic: fix initialization error with clang
This patch fixes the following compiler error raised by clang 3.3
on FreeBSD 10:

  CC enic_clsf.o
lib/librte_pmd_enic/enic_clsf.c:99:25: fatal error: missing field 'u' initializer [-Wmissing-field-initializers]
        struct filter fltr = {0};

It fixes it by changing the initializer to set a named field to zero,
thereby automatically setting the rest of the unnamed fields also to
zero.

a3a03e13a6 af_packet: add compile-time checks for kernel-specific options
This allows the PMD to compile with kernels that don't support the
options in question.  The "#if defined(...)" lines are a bit ugly,
but I don't know of any better way to accomplish the task.

3e7b87dddb doc: add freebsd ports
Since the DPDK is now part of the BSD ports collection, we should
recommend installing from ports as the best way to get it up and
running.
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
needed when installing DPDK itself from ports.

f9e2411af0 doc: adjust line lengths in freebsd guide
The FreeBSD GSG rst files had very inconsistent line lengths for text
within paragraph blocks. Sometimes a line would be very short, while often
lines would be quite long.
This patch adjusts the formatting of the rst files so that lines break
at approx the 80-character mark, as is standard in the DPDK source code.
