Log Message:
Fix that brconfig <bridge> (addr) can't show a large number of MAC addresses
The command shows only 256 addresses at maximum even if a bridge caches more
addresses. It occurs because the kernel doesn't return an error if the command
passes a short buffer that can't store all cached addresses; the kernel fills
cached addresses as much as possible and returns it without telling that the
result is truncated.
Fix the issue by telling a required size of a buffer if a buffer passed from the
command is not enough, which lets the command retry with an enough buffer.
