From b4a488d1824a2cc3514f9ee1298d805bd5edc893 Mon Sep 17 00:00:00 2001 From: Stephen Hemminger Date: Thu, 30 Aug 2007 22:16:22 -0700 Subject: [BRIDGE]: Fix OOPS when bridging device without ethtool. Bridge code calls ethtool to get speed. The conversion to using only ethtool_ops broke the case of devices without ethtool_ops. This is a new regression in 2.6.23. Rearranged the switch to a logical order, and use gcc initializer. Ps: speed should have been part of the network device structure from the start rather than burying it in ethtool.
