From 8bead349c63fc89578b37e12e786390dcf7cbe37 Mon Sep 17 00:00:00 2001 From: Wei Dai Date: Thu, 12 Jan 2017 22:53:25 +0800 Subject: [PATCH] net/ixgbe/base: support XFI backplane for X550 Add initial support for a XFI backplane interface on some new platforms. The XFI backplane requires a custom tuned link. Hardware/Firmware owns the link config for XF backplane and software must not interfere.
