From c4900be053d376dfe4f603d000aa5e4c60745dec Mon Sep 17 00:00:00 2001 From: Donald Skidmore Date: Thu, 20 Nov 2008 21:11:42 -0800 Subject: ixgbe: add SFP+ driver support This patch adds support for SFP+ PHY in the following device ID's (10DB, 10F1, 10E1). These SFP+ PHY's are accessed via an I2C interface so the patch also includes functions to support this. Another feature of note is that the PHY is pluggable and some rearchitecting was needed to support this.
