This script ease testing of basic initializations and Rx/Tx bursts.
It may help to check obvious regressions.
In order to run it on a standard development machine, it doesn't use
neither hugepages nor real interfaces.
The optional parameters are:
- build directory (default: build)
- coremask (default: 3 i.e. cores 0 and 1)

There was a request for an abi validation utilty for the ongoing ABI stability
work. As it turns out there is a abi compliance checker in development that
seems to be under active development and provides fairly detailed ABI compliance
reports. Its not yet intellegent enough to understand symbol versioning, but it
does provide the ability to identify symbols which have changed between
releases, along with details of the change, and offers developers the
opportunity to identify which symbols then need versioning and validation for a
given update via manual testing.
This script automates the use of the compliance checker between two arbitrarily
specified tags within the dpdk tree. To execute enter the $RTE_SDK directory
and run:
./scripts/validate_abi.sh $GIT_TAG1 $GIT_TAG2 $CONFIG
where $GIT_TAG1 and 2 are git tags and $CONFIG is a config specification
suitable for passing as the T= variable in the make config command.
Note the upstream source for the abi compliance checker is here:
http://ispras.linuxbase.org/index.php/ABI_compliance_checker
It generates a report for each DSO built from the requested tags that developers
can review to find ABI compliance issues.

Null PMD is a driver of the virtual device particularly designed to measure
performance of DPDK PMDs. When an application call rx, Null PMD just allocates
mbufs and returns those. Also tx, the PMD just frees mbufs.
The PMD has following options.
- size: specify packe size allocated by RX. Default packet size is 64.
- copy: specify 1 or 0 to enable or disable copy while RX and TX.
Default value is 0(disabled).
This option is used for emulating more realistic data transfer.
Copy size is equal to packet size.
To use the PMD, enable CONFIG_RTE_BUILD_SHARED_LIB in config file. Then
compile the PMD as shared library. The library can be linked using '-d'
option when an application invokes.
Here is an example.
$ sudo ./testpmd -c f -n 4 -d librte_pmd_null.so \
--vdev 'eth_null0' --vdev 'eth_null1' -- -i --no-flush-rx
If testpmd is compiled with CONFIG_RTE_BUILD_SHARED_LIB, it may need to
specify more libraries using '-d' option.

This PMD manages all variants of Mellanox ConnectX-3 (EN 40, EN 10, Pro EN
40) as well as their virtual functions in SR-IOV context through IB Verbs
(libibverbs) and the dedicated user-space driver (libmlx4).
It is disabled by default due to dependencies on these libraries and only
supports Linux userland at the moment partly because /sys (sysfs) support is
required.

This script looks for types, macros and functions in header files using

This patch contains an example for link bonding mode 6.
It interact with user by a command prompt. Available commands are:
Start - starts ARP_thread which respond to ARP_requests and sends
ARP_updates (this
Is enabled by default after startup),
Stop -stops ARP_thread,
Send count ip - send count ARP requests for IP,
Show - prints basic bond information, like IPv4 statistics from clients
Help,
Quit.
The best way to test mode 6 is to use this example together with
previous patch:
[PATCH 3/4] bond: add debug info for mode 6 link bonding.
Connect clients thru switch to bonding machine and send:
arping -c 1 bond_ip or
generate IPv4 traffic to bond_ip (IPv4 traffic from different clients
should be then balanced on slaves in round robin manner).
