This is a note to let you know that I've just added the patch titled vmxnet3: correctly report csum_level for encapsulated packet to the 6.0-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: vmxnet3-correctly-report-csum_level-for-encapsulated.patch and it can be found in the queue-6.0 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 2540f020e9cb2f80d18494054ad395c98e4d2f2c Author: Ronak Doshi <doshir@xxxxxxxxxx> Date: Tue Dec 20 12:25:55 2022 -0800 vmxnet3: correctly report csum_level for encapsulated packet [ Upstream commit 3d8f2c4269d08f8793e946279dbdf5e972cc4911 ] Commit dacce2be3312 ("vmxnet3: add geneve and vxlan tunnel offload support") added support for encapsulation offload. However, the pathc did not report correctly the csum_level for encapsulated packet. This patch fixes this issue by reporting correct csum level for the encapsulated packet.
