From 75856175c26f89198ec64eb2480ed00c4a39a5d6 Mon Sep 17 00:00:00 2001 From: Linas Vepstas Date: Wed, 13 Dec 2006 15:10:06 -0600 Subject: [PATCH] Spidernet remove rxramfull tasklet Get rid of the rxramfull tasklet, and let the NAPI poll routine deal with this situation. (The rxramfull interrupt is simply stating that the h/w has run out of room for incoming packets).
