There is a lot constantly raising discussions related to networking
stack performance/changes.
I'll try to summarize current problems and possible solutions from my
point of view.

Hello list.
We currently have VLAHWFILTER functionality allowing underlying
physical/virtual interfaces to be aware of vlans stacked on them.
However, this knowledge is only used to program NIC hw filter (or to
broadcast to member ifaces in lagg case).
Proposed idea is to save vlan ifp pointer

Today more and more NICs are capable of splitting traffic to different
Rx/TX rings permitting OS to dispatch this traffic on different CPU
cores. However, there are some problems that arises from using multi-nic

Currently we need to acquire 2 read locks to perform simple 6-byte

It seems that acquiring lle lock for fast path (main traffic flow) is
not necessary even with current code.

I'm quite stuck with bad forwarding performance on many FreeBSD boxes

Typical configuration is E5645 / E5675 @ Intel 82599 NIC.

not much gain though.

When I am trying to understand how Elf executable works I am only getting to few

Googling many constants like R_386_PC32, R_386_TLS_LD only yields some

Anybody knows where to read more about the Elf format?
