Just tried to enable larger mtu on interface, and failed, even i try to
disable both of mentioned in dmesg offloads.

Here is what i did:
ifconfig eth1 mtu 2000
got dmesg:

ethtool -K eth1 rxhash off

Thanks for the report. We are aware of the issue and have already begun
working on a patch to resolve the issue.
Bruce.

This is already known and discussed on previous threads. If you look at
the system log file you will see a message from the driver which states
"Jumbo frames cannot be enabled when both receive checksum offload and
receive hashing are enabled. Disable one of the receive offload features
before enabling jumbos." A patch that removes this incompatibility is
currently in test here at Intel and should be passed upstream soon.
Thanks,
Bruce.

it's the same on kernel 3.4.3.
I can't activate jumbo frames
my mobo is S5000PAL
