Subject: [PATCH v1 net-next 03/14] ipv6: Remove IPV6_ADDRFORM support for IPPROTO_UDPLITE.
Date: Mon, 29 May 2023 18:03:37 -0700 [thread overview]
Message-ID: <20230530010348.21425-4-kuniyu@amazon.com> (raw)
In-Reply-To: <20230530010348.21425-1-kuniyu@amazon.com>
The previous commit removes UDP-Lite v6 support, so conversion
from UDP-Lite v6 to v4 never occurs.
