From 815377fe344c799228ca6278613ca3100b069ad5 Mon Sep 17 00:00:00 2001 From: Jan Engelhardt Date: Wed, 8 Oct 2008 11:35:14 +0200 Subject: [PATCH] netfilter: ebt_among: obtain match size through different means The function signatures will be changed to match those of Xtables, and the datalen argument will be gone. ebt_among unfortunately relies on it, so we need to obtain it somehow.
