| Description: SO_REUSEPORT may not exist in running kernel |
| When userspace defines SO_REUSEPORT we will attempt to enable socket |
| port number reuse. However if the running kernel does not support |
| this call it will fail preventing daemon startup. If this call is |
| present but fails ENOPROTOOPT then we know that actually the kernel |
| does not support it and we should continue as if we did not have the |
| call at all. (LP: #1228204) |
| . |
| This patch could be removed from the debian package after jessie release. |
