From: jmatthew Date: Fri, 24 Aug 2018 12:35:10 +0000 (+0000) Subject: Include the list of multicast groups in the rx filter configuration. X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=b12ece3d4a94df26042db929a84544b5503c549e;p=openbsd Include the list of multicast groups in the rx filter configuration. The adapter reads this from host memory, so we allocate a new page for it. The rx filter code ends up looking a lot more like other drivers as a result. --- diff --git a/sys/dev/pci/if_bnxt.c b/sys/dev/pci/if_bnxt.c index 89699978956..6f3fe0fdcf0 100644 --- a/sys/dev/pci/if_bnxt.c +++ b/sys/dev/pci/if_bnxt.c @@ -1,4 +1,4 @@ -/* $OpenBSD: if_bnxt.c,v 1.8 2018/08/24 02:26:31 jmatthew Exp $ */ +/* $OpenBSD: if_bnxt.c,v 1.9 2018/08/24 12:35:10 jmatthew Exp $ */ /*- * Broadcom NetXtreme-C/E network driver. * @@ -151,9 +151,6 @@ struct bnxt_vnic_info { uint16_t lb_rule;
