From 9c9211a3fc7aa41b2952765b62000443b3bb6f23 Mon Sep 17 00:00:00 2001 From: Hangbin Liu Date: Fri, 10 Dec 2021 16:59:58 +0800 Subject: net_tstamp: add new flag HWTSTAMP_FLAG_BONDED_PHC_INDEX Since commit 94dd016ae538 ("bond: pass get_ts_info and SIOC[SG]HWTSTAMP ioctl to active device") the user could get bond active interface's PHC index directly. But when there is a failover, the bond active interface will change, thus the PHC index is also changed. This may break the user's program if they did not update the PHC timely. This patch adds a new hwtstamp_config flag HWTSTAMP_FLAG_BONDED_PHC_INDEX. When the user wants to get the bond active interface's PHC, they need to add this flag and be aware the PHC index may be changed. With the new flag. All flag checks in current drivers are removed. Only the checking in net_hwtstamp_validate() is kept. Suggested-by: Jakub Kicinski Signed-off-by: Hangbin Liu Signed-off-by: David S.
