Hi everybody, Currently I am writing a piece of code to test HW timestamping on e1000 during reception, which runs on FreeBSD 12, but unfortunately it seems that it isn't working.
The socket is created and configured as follows: sockfd = socket(AF_INET, SOCK_DGRAM, 0); int on = 1; setsockopt(sockfd, SOL_SOCKET, SO_TIMESTAMP, &on, sizeof(on)); After recvmsg() is called, cmsg_type of received control messages are printed out with help of the control message routines (https://www.freebsd.org/cgi/man.cgi?query=CMSG_DATA). SCM_TIME_INFO should be printed out but it's not. Is there any configuration missing? Does e1000 support HW timestamping right? I will appreciate any help.
