do you know of the kernel API functions that are used to built a sk_buff?

i am interested in where the kernel actually fills the struct sk_buff that is about to be transmitted by the
network card.
the struct is not filled in the driver level, because (i believe) the driver already gets a 'ready-to-take-off'
sk_buff that can be send.
maybe the function that calls the xmit() function of the corresponding driver, builts the sk_buff.
but actually, i dont know for sure.

there must be a function or several that are responsible for the correct filling of a sk_buff struct, depending
on the desired packet, like syn or rst flag set.

hope i've made myself clear enough.

best regards
