increments of 1 with 750 receive
buffers as the default value. For 10
Gbps adapters, the range of valid
receive buffers is 0 to 3000 in
increments of 50 with 0 receive
buffers as the default value.

not supported on Windows
Server 2003 due to a
limitation in the operating
system. However,
BCM5709, BCM57710, and
BCM57711 network
adapters support IPv6
Receive Side Scaling on
Windows Server 2008 and
later.
