From 213fa517424f4d1c83e7cf486c0f113bd874c32c Mon Sep 17 00:00:00 2001 From: Stefan Wahren Date: Mon, 16 Jul 2018 21:33:40 +0200 Subject: [PATCH 359/454] net: lan78xx: fix rx handling before first packet is send As long the bh tasklet isn't scheduled once, no packet from the rx path will be handled. Since the tx path also schedule the same tasklet this situation only persits until the first packet transmission. So fix this issue by scheduling the tasklet during ndo_open like in usbnet.
