    packet: avoid warnings when high-order page allocation fails · 719bfeaa
    Eric Dumazet authored
    Latest tcpdump/libpcap triggers annoying messages because of high order page
    allocation failures (when lowmem exhausted or fragmented)
    
    These allocation errors are correctly handled so could be silent.
