Subject: [PATCH 2/5] Compare address and interface index for allowed interface
|
|
|
8e0267 |
|
|
|
8e0267 |
If interface is recreated with the same address but different index, it
|
|
|
8e0267 |
would not change any other parameter.
|
|
|
8e0267 |
|
|
|
8e0267 |
Test also address family on incoming TCP queries.
