Message-Id: <1291408744-2392-1-git-send-email-dm@chelsio.com> Date: Fri, 3 Dec 2010 12:39:04 -0800 From: Dimitris Michailidis <dm@...lsio.com> To: netdev@...r.kernel.org Subject: [PATCH net-2.6] cxgb4: fix MAC address hash filter Fix the calculation of the inexact hash-based MAC address filter. It's 64 bits but current code is missing a ULL. Results in filtering out some legitimate packets.
