From 16fe9d74f14ed74af778c5db7f9129e29916f4a7 Mon Sep 17 00:00:00 2001 From: Michael Chan Date: Tue, 13 Dec 2005 21:09:54 -0800 Subject: [TG3]: Fix 5704 single-port mode If the dual-port 5704 is configured as a single-port device with only one PCI function, it would trigger a BUG() condition in tg3_find_5704_peer(). This fixes the problem by returning its own pdev if the peer cannot be found. Signed-off-by: Michael Chan Signed-off-by: David S.
