Subject: [PATCH next-queue v3 2/3] igc: Enable PCIe PTM
Date: Mon, 22 Mar 2021 09:18:21 -0700 [thread overview]
Message-ID: <20210322161822.1546454-3-vinicius.gomes@intel.com> (raw)
In-Reply-To: <20210322161822.1546454-1-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).
