    bridge: only provide proxy ARP when CONFIG_INET is enabled · d92cfdbb
    Arnd Bergmann authored
    When IPV4 support is disabled, we cannot call arp_send from
    the bridge code, which would result in a kernel link error:
    
    net/built-in.o: In function `br_handle_frame_finish':
    :(.text+0x59914): undefined reference to `arp_send'
    :(.text+0x59a50): undefined reference to `arp_tbl'
    
    This makes the newly added proxy ARP support in the bridge
    code depend on the CONFIG_INET symbol and lets the compiler
    optimize the code out to avoid the link error.
