The patch requested in bug 1454892 has all the commits in this bug as pre-reqs. Is it okay to mark this bug as a duplicate of bug 1454892 so all these commits can be sent together as one SRU request?
It looks like testing is good for both bugs in Vivid. I'll work on building test kernels for Utopic, Trusty and Precise.

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
