This series fixes netdevsim's inconsistent behavior between carrier and link/unlink state.
More specifically, this fixes a bug that the carrier goes DOWN although two netdevsim were peered, depending on the order of peering and ifup. Especially in a NetworkManager-enabled environment, netdevsim test fails because of this.
The first patch fixes the bug itself in netdevsim/bus.c by adding netif_carrier_on() into a proper function. The second patch adds a regression test for this bug.
Changelog ========= v1 -> v2 - Rebase to the latest net/main - Separate TFO tests from this series - Separate netdevsim test improvement from this series - v1: https://lore.kernel.org/netdev/cover.1767032397.git.yk@y-koj.net/
