[Qemu-devel] [PATCH] linux-user: Add missing IP_TOS, IPV6_TCLASS and IPV6_RECVTCLASS sockopts |
Date: |

User-agent: |
Mutt/1.7.1 (2016-10-04) |
When running the nslookup or dig command with IPv6, the following qemu
warnings will be shown:
Unsupported ancillary data: 0/1
Unsupported setsockopt level=41 optname=67
Unsupported setsockopt level=41 optname=66
Unsupported ancillary data: 41/67
This patch adds the missing code to quiet those warnings.
