(2) the functionalities offered by sk_buff can be categorized into: memory management; data manipulation; list manipulation. what functions are supposed to be invoked in order for the skb to be sent or received? (3) i know that i still have to read a lot, but where can i find/read resources about the sending/receiving of an sk_buff from one layer to another; one protocol to another? the net/core/skbuff.c does not offer much explanation on the above querries. _______________________________ Do you Yahoo!?
