net: handle ARPHRD_PPP in dev_is_mac_header_xmit() 2023-09-19T10:20:22+00:00 Nicolas Dichtel nicolas.dichtel@6wind.com 2023-08-23T13:41:02+00:00 a9864e126b73f20e52f76ca8dbcf56861a16d614 commit a4f39c9f14a634e4cd35fcd338c239d11fcc73fc upstream. The goal is to support a bpf_redirect() from an ethernet device (ingress) to a ppp device (egress). The l2 header is added automatically by the ppp driver, thus the ethernet header should be removed.
