tests: add spdx license header to test unit/link/network/conf files Those are all consumed by our parser, so they all support comments. I was considering whether they should have a license header at all, but in the end I decided to add it because those files are often created by copying parts of real unit files. And if the real ones have a license, then those might as well. It's easier to add it than to make an exception. 2021-10-17 16:07:22 +00:00			`# SPDX-License-Identifier: LGPL-2.1-or-later`

network: Add `IgnoreDdontFragment=` option for Fragmentation control (#28131) From `ip-link(8)`: > [no]ignore-df - enables/disables IPv4 DF suppression on this tunnel. Normally datagrams that exceed the MTU will be fragmented; the presence of the DF flag inhibits this, resulting instead in an ICMP Unreachable (Fragmentation Required) message. Enabling this attribute causes the DF flag to be ignored. If this option is enabled for a GRE/GRETAP tunnel, the `DF` flag in the outer IP header will not inherit the inner IP header's `DF` flag. This is useful to transfer packets that exceed the MTU of the underlay network. 2023-06-29 10:11:52 +00:00			`IgnoreDontFragment=true`
