From 3b89b511ea0c705cc418440e2abf9d692a556d84 Mon Sep 17 00:00:00 2001 From: Dan Carpenter dan.carpenter@oracle.com Date: Thu, 23 Jun 2022 16:32:32 +0300 Subject: [PATCH] net: fix IFF_TX_SKB_NO_LINEAR definition

The "1<<31" shift has a sign extension bug so IFF_TX_SKB_NO_LINEAR is 0xffffffff80000000 instead of 0x0000000080000000.
