[cgl_discussion] Open source projects for requirements

There are a couple of requirements in the draft performance
specification that need clarification as to which open source projects
(if any) apply to them.  They are:

PRF.4.1  Low Software Overhead For Message Latency
Description: OSDL CGL specifies that carrier grade Linux shall provide a
new communication service scheme to support low software latency based
on a zero-copy architecture that uses memory mapping and a simplified
path between the user and physical layer to reduce abstract layer
overhead.

PRF.4.4  ARP Cache Immediate Flush On Client
Description: OSDL CGL specifies that carrier grade Linux shall enable an
immediate update to the address resolution protocol (ARP) cache on
client nodes when an IP or interface configuration changes to enable
fast IP address migration on the client side.

Feedback on both the wording of these requirements and projects that
relate to these requirements are welcome.  The origin of these
requirements is a bit hazy and they may be relegated to roadmap items if
we can't clarify them.

TIA
