X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a79878f00dad97d03a3e62a48b06227d55ae5fe4;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git [ARP]: Move inet_addr_type call after simple error checks in arp_contructor. The neighbour entry will be destroyed in the case of error, so it is pointless to perform constly routing table lookup in this case. Signed-off-by: Denis V. Lunev Signed-off-by: David S.
