Much of the scanning work was supported by Atheros. The 11n work was supported by Marvell. 2007-06-05T00:32:01Z David Christensen davidch@FreeBSD.org 2007-06-05T00:32:01Z urn:sha1:051e756190ba00a5e7d7a5cee91930ace72523f1 which support a 2.5Gbps mode over fiber using next page extensions during autonegotiation.
