user space checksum

[raz ben jehuda <razb@xxxxxxxxxxx>]

I do not know if this was ever suggested.so i'll try any way.
Why not give the user the chance to supply the kernel/card with the
checksums instead of having the kernel/network card do the work ? 
This is because a user is aware to the data he sends and he can optimize
the data checksum calculations more than anyone else. for instance a web
server sends its html pages, which are static data. it can pre-calculate
the checksums.

Anyone ?
