Is the VPP project addressing the use of master/slave nomenclature in the code
base,
documentation and CLI? We are doing this for DPDK and it would be good if the
replacement wording used in DPDK matched the wording used in FD.io projects.

Looks like a change went into DPDK which rearranged the rte_sched (hQOS) fields
in the next release. This breaks build on VPP.
Not hard to fix in VPP, but let's wait and see if DPDK intends to break API or
if it was just developer not paying attention.

The VMBus changes keep failing build on CentOs because of
missing install of new dependency (libuuid-devel).
See: https://gerrit.fd.io/r/15311
The RPM_DEPENDS is updated in the Makefile, and it works on a local CentOs 7.6
VM.
I suspect that the build CI doesn't do 'make install-dep' so it
doesn'
Build is failing for me on latest up to date version of Fedora and VPP.
This is a clean new VM, and did the install of dependencies but Makefile
is still confused.
$ make build
Please install missing RPMs: \npackage cmake3 is not installed\n
by executing "make install-dep"\n

I just discovered the clang-format file and noticed that Linux kernel used
the ForEachMacros option to format for() wrappers.
VPP seems to be riddled with INDENT-OFF when it does vector loops. (2123 times!)
Has anyone looked into replacing these with ForEachMacros?

I was playing around with sample plugin, it looks like the documentation is out
of date
with current VPP especially autoconf etc.
Could someone walkthrough the documentation and make sure the example works.

Is it possible to do Read Copy Update with VPP? Either using Userspace RCU

or manually. RCU is very efficient way to handle read mostly tables and other
dynamic cases

The DPDK plugin has problems with non-PCI devices. It is using the old DPDK
assumptions that all
devices are really PCI. There are various special cases in there already, but
it needs to be
fixed properly by using the DPDK bus model.
The fix isn't hard, my question is how far back in DPDK histor

A process can do introspection by doing dlopen with NULL as filename. Then

Having supported hardware list buried in DPDK plugin code is a nuisance.
Could the table be generated at build time maybe from pmdinfo or using
dlopen to lookup symbols?

I noticed that the PCI domain in VPP is limited to 16 bits.
This is a problem on Azure/Hyper-V and other virtual environments.
In these environments, the host will generate a 32 bit synthetic value
when passing a PCI device through. The Linux kernel has 32 bit PCI
domains, and libpciaccess used by
