If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit c1bf299b63cc2744c3612c55abd5c88326e7c07f Author: Huanhuan Wang <huanhuan.wang@xxxxxxxxxxxx> Date: Thu Mar 2 10:58:30 2023 +0100 nfp: fix esp-tx-csum-offload doesn't take effect [ Upstream commit 1cf78d4c4144ffdbc2c9d505db482cb204bb480b ] When esp-tx-csum-offload is set to on, the protocol stack shouldn't calculate the IPsec offload packet's csum, but it does. Because the callback `.ndo_features_check` incorrectly masked NETIF_F_CSUM_MASK bit.
