Paul Chaignon 5a15a050df bpf: Clarify the meaning of BPF_F_PSEUDO_HDR ... In the bpf_l4_csum_replace helper, the BPF_F_PSEUDO_HDR flag should only be set if the modified header field is part of the pseudo-header. If you modify for example the UDP ports and pass BPF_F_PSEUDO_HDR, inet_proto_csum_replace4 will update skb->csum even though it shouldn't (the port and the UDP checksum updates null each other).
