Date: Fri, 25 Nov 2016 17:47:35 +0000
From: Edward Cree <ecree@...arflare.com>
To: <linux-net-drivers@...arflare.com>, <davem@...emloft.net>
CC: <bkenward@...arflare.com>, <netdev@...r.kernel.org>
Subject: [PATCH net-next 2/2] sfc: remove obvious Falcon-related code
Removed Falcon NIC functions, Falcon PHY code, and EFX_REV_FALCON_*, then
fixed up everything that referenced them.
