Subject: [PATCH net-next] i40evf: hide unused variable
Date: Wed, 19 Apr 2017 19:29:48 +0200
Message-Id: <20170419173008.3648215-1-arnd@arndb.de>
Sender: linux-kernel-owner@vger.kernel.org
Content-Length: 1532

On architectures with larger pages, we get a warning about an unused variable:

drivers/net/ethernet/intel/i40evf/i40evf_main.c: In function 'i40evf_configure_rx':
drivers/net/ethernet/intel/i40evf/i40evf_main.c:690:21: error: unused variable 'netdev' [-Werror=unused-variable]

This moves the declaration into the #ifdef to avoid the warning.

Fixes: dab86afdbbd1 ("i40e/i40evf: Change the way we limit the maximum frame size for Rx")
