From a42e534f1b6be7f2f68f83d29588c3f2736b4d25 Mon Sep 17 00:00:00 2001 From: Jay Vosburgh Date: Tue, 29 Jan 2008 18:07:43 -0800 Subject: bonding: fix parameter parsing My last fix (commit ece95f7fefe3afae19e641e1b3f5e64b00d5b948) didn't handle one case correctly. This resolves that, and it will now correctly parse parameters with arbitrary white space, and either text names or mode values.
