Mihai Parparita 2b4140ee46 wgengine/router: avoid unncessary routing configuration changes ... The iOS and macOS networking extension API only exposes a single setter for the entire routing and DNS configuration, and does not appear to do any kind of diffing or deltas when applying changes. This results in spurious "network changed" errors in Chrome, even when the `OneCGNATRoute` flag from df9ce972c7 is used (because we're setting the same configuration repeatedly). Since we already keep track of the current routing and DNS configuration in CallbackRouter, use that to detect if they're actually changing, and only invoke the platform setter if it's actually necessary. Updates #3102 Signed-off-by: Mihai Parparita <mihai@tailscale.com> (cherry picked from commit 06aa141632)		2022-07-05 09:56:51 -07:00
