| |
Hello, Can anybody explain me how ethernet header is added to every packet outgoing? I check eth.c file and found eth_header that is used for adding ethernet header on skbuff packet. But does each packet calls this function? I think not as theres a cache header function used that cache ethernet header entry. So my main question is that when my machine first contacted to any other pc in LAN does it calls eth_header and when require to send any type of packet to same machine i thnik eth_cache_header is used is that right??? Then can it be possible that if my machine not contacted to any cached entry machine then eth_header will be called again to build eth header for that machine? In an all when functions in eth.c will be called/not called eth_header,eth_header_cache,eth_header_parse,eth_header_cache_update??? Please kindly help me to identify it. Thanks in advance. regards, linux_lover.
