Have you confirmed whether this product ID is unique to the products that support this feature or if it's also re-used in other products? For Dell's devices there are very specific tests that make sure that this feature only applies on the products it is supposed to and nothing else (For example RTL8153-AD checks variant as well as effuse value) (Example two: RTL8153-BND is a Dell only part). > > BugLink: https://bugs.launchpad.net/bugs/1827961/comments/30 > Signed-off-by: Kai-Heng Feng <kai.heng.feng@xxxxxxxxxxxxx> > --- > drivers/net/usb/r8152.c | 3 ++- > 1 file changed, 2 insertions(+), 1 deletion(-) > > diff --git a/drivers/net/usb/r8152.c b/drivers/net/usb/r8152.c > index c5ebf35d2488..42dcf1442cc0 100644 > --- a/drivers/net/usb/r8152.c > +++ b/drivers/net/usb/r8152.c > @@ -6657,7 +6657,8 @@ static int rtl8152_probe(struct usb_interface *intf, > } > > if (le16_to_cpu(udev->descriptor.idVendor) == VENDOR_ID_LENOVO && > - le16_to_cpu(udev->descriptor.idProduct) == 0x3082) > + (le16_to_cpu(udev->descriptor.idProduct) == 0x3082 || > + le16_to_cpu(udev->descriptor.idProduct) == 0xa387)) > set_bit(LENOVO_MACPASSTHRU, &tp->flags); > > if (le16_to_cpu(udev->descriptor.bcdDevice) == 0x3011 && udev->serial > && > -- > 2.17.1
