From dc668910f4eaa233c241d43d96ed6b0b9258cc43 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Micha=C5=82=20Miros=C5=82aw?= Date: Thu, 7 Apr 2011 03:35:07 +0000 Subject: [PATCH] net: tg3: convert to hw_features MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Cleanup hint: Some features are calculated in tg3_get_invariants() and the rest in its caller --- tg3_init_one().
