Revision 2284bbd0cf3981462dc6d729c89851c66b05a66a authored by Leon Schuermann on 11 January 2021, 19:03:15 UTC, committed by Jakub Kicinski on 13 January 2021, 04:00:51 UTC 
r8153_ecm: Add Lenovo Powered USB-C Hub as a fallback of r8152
 
This commit enables the use of the r8153_ecm driver, introduced with
commit c1aedf015ebdd0 ("net/usb/r8153_ecm: support ECM mode for
RTL8153") for the Lenovo Powered USB-C Hub (17ef:721e) based on the
Realtek RTL8153B chip.

This results in the following driver preference:

- if r8152 is available, use the r8152 driver
- if r8152 is not available, use the r8153_ecm driver

This is done to prevent the NIC from constantly sending pause frames
when the host system enters standby (fixed by using the r8152 driver
in "r8152: Add Lenovo Powered USB-C Travel Hub"), while still allowing
the device to work with the r8153_ecm driver as a fallback.

	tristate "PPS support"
	help
	  PPS (Pulse Per Second) is a special pulse provided by some GPS
	  antennae. Userland can use it to get a high-precision time
	  reference.

	  Some antennae's PPS signals are connected with the CD (Carrier
	  Detect) pin of the serial line they use to communicate with the
	  host. In this case use the SERIAL_LINE client support.

	  Some antennae's PPS signals are connected with some special host
	  inputs so you have to enable the corresponding client support.

	  To compile this driver as a module, choose M here: the module
	  will be called pps_core.ko.

if PPS

config PPS_DEBUG
	bool "PPS debugging messages"
	help
	  Say Y here if you want the PPS support to produce a bunch of debug
	  messages to the system log.  Select this if you are having a
	  problem with PPS support and want to see more of what is going on.

config NTP_PPS
	bool "PPS kernel consumer support"
	depends on !NO_HZ_COMMON
	help
	  This option adds support for direct in-kernel time
	  synchronization using an external PPS signal.

	  It doesn't work on tickless systems at the moment.
