> Subject: [PATCH v2 1/3] net/ixgbe: initialize PTP to system time
>
> Currently, ixgbe driver initializes PTP timestamp to 0. This is different from
> what kernel driver does (which initializes it to system time).
>
> Align the DPDK driver to kernel driver by setting PTP timestamp to system time
> when enabling PTP.
>
> Note that ixgbe driver always uses zero-based timestamps for PTP, so we
> would only ever update the internal timecounter and not the actual NIC
> registers.
>
> Implementation note: in order to get access to clock_gettime on MinGW, we
> have to use rte_os_shim.h header, which provides a wrapper around that
> function. However, what it *also* provides is wrapper macros around various
> other OS-related functions such as read(). Due to one of the mailbox ops in
> base code being called "read", MinGW will misinterpret a call into that op as
> an
> attempt to call read() the OS function, and produce a compile error. This is
> being worked around by using parentheses around access to the read op.
