Subject: [PATCH 4.9 04/32] net: lan78xx: fix rx handling before first packet is send
Date: Sat, 4 Aug 2018 11:00:54 +0200 [thread overview]
Message-ID: <20180804082650.113689062@linuxfoundation.org> (raw)
In-Reply-To: <20180804082649.908295462@linuxfoundation.org>
4.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Stefan Wahren <stefan.wahren@i2se.com>
[ 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.
