From 0ea96930bcd85734da46de0cd44d1d0408cbb9be Mon Sep 17 00:00:00 2001 From: Aurelien Jarno Date: Sun, 10 Jun 2012 23:18:44 +0200 Subject: [PATCH] lan9118: fix multicast filtering The lan9118 emulation tries to compute the multicast index by calling directly the crc32() function from zlib, but fails to get the correct result. Use the common compute_mcast_idx() function instead, which gives the correct result. This fixes IPv6 support.
