netgraph: porting thins from FreeBSD-4 ==> FreeBSD-5

[Ilia E. Chipitsine]

Dear Sirs,

I want to port some application which uses netgraph.

it uses NG_FREE_DATA ... which is not present in FreeBSD-5.

I could write

#if __FreeBSD__ >= 5
 NG_FREE_M
 NG_FREE_ITEM
#else
 NG_FREE_DATA
#endif


... can anyone tell me WHEN those changes happen to netgraph ?

Cheers,
Ilia Chipitsine
