rGb4174079576a: bridge.4: describe new MTU behaviour

Summary

1865ebfb12 changed if_bridge to have it change the MTU on newly added
interfaces to match the if_bridge MTU, rather than rejecting them for
having an incorrect MTU.

Update the man page to reflect this, as pointed out by woodsb02.

Small typo, the rest looks good to me for the man page.

share/man/man4/bridge.4
516–517	s/wich/which/

Looks good! Can I propose also adding some additional info describing the new behaviour when the MTU of an existing bridge is changed?

share/man/man4/bridge.4
130–132	Perhaps add a new line that also explains the new behaviour when the MTU of a bridge interface is changed. Something like the below. If the MTU of a bridge is changed after its creation, the MTU of all member interfaces is also changed to match.
