ethernet cache question
Hello,
By looking at structure hh_cache it is seen that hh_output is structure variable defined as unsigned long hh_data[HH_DATA_ALIGN(LL_MAX_HEADER) / sizeof(long)]; Then i want to know how its sufficient in linux kernel to copy cache ethernet header entry as memcpy(skb->data - 16, hh->hh_data, 16); other variable defined in hh_cache is not seen as copied to packet structure. How then ethernet header is copied to packet if ethernet header has cache entry stored in hh_cache structure defiend in /usr/src/include/netdevice.h regards, cranium |
