"link_cksum_offload" controls tx/rx checksum enabling as well.
Framework seems not having this as tunable so far.
Its because it doesn't need to be tunable. The framework negotiates
this feature with the drivers... it always enables the feature if the
driver can support it. There is never any reason to disable it.
I had met questions from customer who complained his/her application
failed because all 0x0000 in TCP/IP's checksum field. If we provide
customer with better grained tuning over checksum capability, he/she
might be able to shoot or debug problems more efficiently. And we could
see most morden day drivers in Windows/Linux have tx/rx checksum tunable
respectively. I believe at least for debug/workaround reasons, we should
have this as an option to customer.
