From 967868627207c34298c6fe59f12a1ab3f8aba0b4 Mon Sep 17 00:00:00 2001 From: Stefan Wahren Date: Sat, 28 Jul 2018 09:52:10 +0200 Subject: [PATCH] net: lan78xx: fix rx handling before first packet is send [ Upstream commit 136f55f660192ce04af091642efc75d85e017364 ] 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 after link reset.
