Subject: [PATCH 2.6.18] declance: Fix RX ownership handover

 The change for PMAD support introduced a bug, where the ownership of RX 
descriptors was given back to the LANCE in the wrong way.  Occasional 
lockups would happen as a result.  This is a fix for this problem.

Signed-off-by: Maciej W. Rozycki <macro@...ux-mips.org>
---
 Tested with the onboard LANCE of a DECstation 5000/133.

 Please apply.
