Subject: [PATCH net v2] net: mvpp2: prs: fix PPPoE with ipv6 packet parse
Date: Thu, 17 Dec 2020 20:37:46 +0200 [thread overview]
Message-ID: <1608230266-22111-1-git-send-email-stefanc@marvell.com> (raw)
From: Stefan Chulski <stefanc@marvell.com>
Current PPPoE+IPv6 entry is jumping to 'next-hdr'
field and not to 'DIP' field as done for IPv4.
Fixes: 3f518509dedc ("ethernet: Add new driver for Marvell Armada 375 network unit")
Reported-by: Liron Himi <lironh@marvell.com>
Signed-off-by: Stefan Chulski <stefanc@marvell.com>
