Hrm, I had thought those other commits had been requested previously, sorry I missed them in the roundup. We'll look at testing the kernel right away. There is another skb-related fix that is still in review upstream and is not yet committed as well.

We need to decorate each outgoing packet with a rndis header and additional rndis state (rndis per-packet state). To manage this state, we currently allocate memory in the transmit path. Eliminate this allocation by requesting additional head room in the skb." This commit introduced a bug since it did not account for the case if the skb was cloned. Fix this bug. https://git.kernel.org/cgit/linux/kernel/git/davem/net- next.git/commit/?id=b56fc3c536541c8081cd5f1f1d101a16c002a365 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1452074/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
