From 0ca43235b34c92278fa903297acef37198ec3e26 Mon Sep 17 00:00:00 2001 From: Stephen Hemminger Date: Wed, 18 Oct 2006 13:39:28 -0700 Subject: [PATCH] [PATCH] sky2: netpoll on dual port cards The sky2 driver uses a single NAPI poll routine for both ports on dual ported cards (because there is a single IRQ and status ring). Netpoll makes assumptions about the relationship between network device and NAPI that aren't correct on the second port, this will cause the port to never clear work. Most systems, just have single port, so not a big issue. The easy fix is just make the second port, not netpoll capable.
