From c3d1182a538fd99b6fe5effa1ab54521c0efb1d1 Mon Sep 17 00:00:00 2001 From: Linas Vepstas Date: Mon, 11 Jun 2007 13:26:50 -0500 Subject: [PATCH] spidernet: silence the ramfull messages Although the previous patch resolved issues with hangs when the RX ram full interrupt is encountered, there are still situations where lots of RX ramfull interrupts arrive, resulting in a noisy log in syslog. There is no need for this.
