I am currently working on PTP , and my requirement is that I should access the receive/transmitted timestamp using the ioctl provided in the driver.
Through the socket ioctl (SIOCDEVPRIVATE) , i am able to get the rtc time. But there are three issues I need to solve
i) Whenever I try to use PTP_GET_TX_TIMESTAMP with ioctl , it always returns 0 in the timestamp field. However, it doesnot return any error value
ii) Whenever I try to use PTP_GET_RX_TIMESTAMP with ioctl , it returns an error message Resource temporarily unavailable.
iii) Also , is there a way through which an interrupt/notification can be passed to userspace application whenever I receive a PTP packet.
I have tried this with kernel version 3.0.35 on iMX6q sabrelite board.
