zero-copy support linux kernel
 

Can some body please give me a pointer on how i can verify that "Zero-copy" support :

http://en.wikipedia.org/wiki/Zero-copy

is enabled in my kernel or not.

Mine is 2.6.9-42.ELhugemem-i686c

I understand as per docs it should be enabled by default after 2.4 kernel but we get custom boxes so want to chk if they have disabled it ?

Thanks in advance.
