From da990a2402aeaee84837f29054c4628eb02f7493 Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Sun, 23 Mar 2008 03:35:12 -0700 Subject: [SUNGEM]: Fix NAPI assertion failure. As reported by Johannes Berg: I started getting this warning with recent kernels: [ 773.908927] ------------[ cut here ]------------ [ 773.908954] Badness at net/core/dev.c:2204 ... If we loop more than once in gem_poll(), we'll use more than the real budget in our gem_rx() calls, thus eventually trigger the caller's assertions in net_rx_action(). Subtract "work_done" from "budget" for the second arg to gem_rx() to fix the bug. Signed-off-by: David S.
