From 9cff866e37eb47780bf34842fcf371e41c5a0639 Mon Sep 17 00:00:00 2001 From: Alexey Brodkin Date: Tue, 13 Aug 2013 17:04:36 +0400 Subject: ethernet/arc/arc_emac - fix NAPI "work > weight" warning Initially I improperly set a boundary for maximum number of input packets to process on NAPI poll ("work") so it might be more than expected amount ("weight"). This was really harmless but seeing WARN_ON_ONCE on every device boot is not nice. So trivial fix ("<" instead of "<=") is here.
