We have VLAN PTP support(via get_ts_info) on kernel, and bond support(by getting active interface via netlink message) on userspace tool linuxptp. But there are always some users who want to use PTP with VLAN over bond, which is not able to do with the current implementation. This patch passed get_ts_info and SIOC[SG]HWTSTAMP ioctl to active device with bond mode active-backup/tlb/alb. With this users could get kernel native bond or VLAN over bond PTP support. Test with ptp4l and it works with VLAN over bond after this patch: ]# ptp4l -m -i bond0.23 ptp4l[53377.141]: selected /dev/ptp4 as PTP clock ptp4l[53377.142]: port 1: INITIALIZING to LISTENING on INIT_COMPLETE ptp4l[53377.143]: port 0: INITIALIZING to LISTENING on INIT_COMPLETE ptp4l[53377.143]: port 0: INITIALIZING to LISTENING on INIT_COMPLETE ptp4l[53384.127]: port 1: LISTENING to MASTER on ANNOUNCE_RECEIPT_TIMEOUT_EXPIRES ptp4l[53384.127]: selected local clock e41d2d.fffe.123db0 as best master ptp4l[53384.127]: port 1: assuming the grand master role Signed-off-by: Hangbin Liu <liuhangbin@gmail.com> Signed-off-by: David S.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
