Modified Files: src/sys/net: bpf.c Log Message: bpf.c: support loopback writes when BIOCSHDRCMPLT is set Following changes in r. 1.249 "bpf: support sending packets on loopback interfaces", also allow for this to succeed when the "header complete" flag is set, which is the practice of some tools, e.g., tcpreplay and Scapy. With this change, both of those example tools now work, e.g., Scapy passes "L3bpfSocket - send and sniff on loopback" in its test suite. There are several ways of addressing this issue; this commit is intended to be the most conservative and consistent with the previous changes. (E.g., FreeBSD instead has special handling of this condition in its if_loop.c.)
