Subject: [PATCH next-queue v2 2/3] igc: Enable PCIe PTM
Date: Mon,  9 Nov 2020 22:10:18 -0800	[thread overview]
Message-ID: <20201110061019.519589-3-vinicius.gomes@intel.com> (raw)
In-Reply-To: <20201110061019.519589-1-vinicius.gomes@intel.com>

In practice, enabling PTM also sets the enabled_ptm flag in the PCI
device, the flag will be used for detecting if PTM is enabled before
adding support for the SYSOFFSET_PRECISE ioctl() (which is added by
implementing the getcrosststamp() PTP function).
