Subject: [PATCH net] ibmvnic: Fix IPv6 packet descriptors
Date: Thu, 18 Jan 2018 19:05:02 -0600 [thread overview]
Message-ID: <1516323902-15852-2-git-send-email-tlfalcon@linux.vnet.ibm.com> (raw)
In-Reply-To: <1516323902-15852-1-git-send-email-tlfalcon@linux.vnet.ibm.com>
Packet descriptor generation for IPv6 is broken.
Properly set L3 and L4 protocol flags for IPv6 descriptors.
