From: Michał Mirosław <mirq-linux@...e.qmqm.pl>
To: netdev@...r.kernel.org
Subject: [RFC PATCH] net: ethtool: use C99 array initialization for feature-names table
This depends on Mahesh Bandewar's cleanup of feature bits.
Note: This is why I'd like that patch to include TSO bits as well,
so I can get rid of this ugly NETIF_F_GSO_SHIFT+n.
