From f0ea8bfbc1bcd0ca32011c1335f633f00d9199cf Mon Sep 17 00:00:00 2001 From: Julian Wiedmann Date: Fri, 9 Mar 2018 18:12:56 +0100 Subject: [PATCH] s390/qeth: pass correct length to header_ops->create() We need to pass the *payload* length, not the L2 address length. For qeth (using eth_header()) this is merely a cosmetic change: the parameter only matters when building headers for ETH_P_802_2 or ETH_P_802_3, whereas our fake headers are built with ETH_P_IP / ETH_P_IPV6 / 0.
