From b6e00e94e48fc97e17dc2f40c1668c2bc4b1daf9 Mon Sep 17 00:00:00 2001 From: Russell King Date: Wed, 11 Jan 2017 21:59:40 +0000 Subject: net: phy: add XAUI and 10GBASE-KR PHY connection types XAUI allows XGMII to reach an extended distance by using a XGXS layer at each end of the MAC to PHY link, operating over four Serdes lanes. 10GBASE-KR is a single lane Serdes backplane ethernet connection method with autonegotiation on the link. Some PHYs use this to connect to the ethernet interface at 10G speeds, switching to other connection types when utilising slower speeds. 10GBASE-KR is also used for XFI and SFI to connect to XFP and SFP fiber modules.
