Hello,
Attached is a patch to treat bridge(4) as a loadable module and not as a
compile time kernel option. This fixes the following problem.
Bug:
ARP requests on bridged interfaces are not processed correctly when
loading bridge(4) as a module.
How to repeat:
Load bridge(4) as a module and bridge two interfaces (fxp0, fxp1).
Assign an IP address to fxp0. This IP address is inaccessible to devices
attached to fxp1. Adding static ARP entries resolves the problem.
Regards
Gary
