nic_uio: fix device binding at boot
When loading nic_uio from /boot/loader.conf as specified in the Getting
Started Guide doc, the NIC devices were not bound at boot. Unloading the
nic_uio driver and reloading it would cause them to be bound, however.
The root cause appears to be the fact that when the module is loaded at
boot, the call to find the pci device when parsing the b:d:f parameter
fails to return the device. That means that later on when the device
is probed as part of a PCI scan, no action is taken as it's not recorded
as a device to be used.
We fix this by having the b:d:f string parsed again on probe if the
initial check to see if it's an already-known device fails. In my tests,
this causes the NIC devices to be successfully bound at boot time, as
well as leaving things working as before in the case the module is loaded
post-boot.

For using a DPDK app when iommu is enabled, it requires to

makes DMAR errors because the device has not an IOMMU domain.
Since kernel 3.15, iommu=pt requires to use the internal kernel
DMA API for attaching the device to the IOMMU 1:1 mapping, aka
si_domain. Previous versions did attach the device to that
domain when intel iommu notifier was called.
This is not a problem if the driver does later some call to the
DMA API because the mapping can be done then. But DPDK apps do
not use that DMA API at all.

mk: optimize directory dependencies
Before this patch, the management of dependencies between directories
had several issues:
- the generation of .depdirs, done at configuration is slow: it can take
more than one minute on some slow targets (usually ~10s on a standard
PC without -j).
- for instance, it is possible to express a dependency like:
- app/foo depends on lib/librte_foo
- and lib/librte_foo depends on app/bar
But this won't work because the directories are traversed with a
depth-first algorithm, so we have to choose between doing 'app' before
or after 'lib'.
- the script depdirs-rule.sh is too complex.
- we cannot use "make -d" for debug, because the output of make is used for
the generation of .depdirs.
This patch moves the DEPDIRS-* variables in the upper Makefile, making
the dependencies much easier to calculate. A DEPDIRS variable is still
used to process library dependencies in LDLIBS.
After this commit, "make config" is almost immediate.

Memory init can only fail when access to hugepages (either as primary or

pci: fix device registration on FreeBSD
The FreeBSD implementation wasn't registering new devices
with the device framework on start up. However, common
code attempts to unregister them on shutdown which causes
a SEGFAULT. This fix makes the FreeBSD code do the same
thing as the Linux code for registration.

test: add a new unit test case status
Add a new unit test case status called "unsupported".
This is useful in marking a test case "unsupported" if testcase
returns -ENOTSUP at runtime.

test: store only the test case name
Store only the test case name in unit test case structure.The actor who
renders the test status can add appropriate test status. This enables
adding the new test case status without storing the additional
information in the unit test case structure.

mk: remove invalid phony target
There was a typo in the .PHONY for the test-build target. If we fix the
typo, the test-build target does not work, because it won't match the
'%' target anymore.
So just remove the .PHONY.

maintainers: resign from eal maintenance
I have been a little too busy these past months and could not really
do any real maintainer stuff for dpdk for a while now.
I have no clear idea when I could dedicate more time to dpdk.
So the best thing for the dpdk community would be to move the eal
maintenance to more involved people.
