2021-12-18tsnep: Fix s390 devm_ioremap_resource warningGerhard Engleder1-0/+1
The following warning is fixed with additional config dependencies: s390-linux-ld: drivers/net/ethernet/engleder/tsnep_main.o: in function `tsnep_probe': tsnep_main.c:(.text+0x1de6): undefined reference to `devm_ioremap_resource' Reported-by: kernel test robot <lkp@intel.com> Signed-off-by: Gerhard Engleder <gerhard@engleder-embedded.com> Link: https://lore.kernel.org/r/20211216200154.1520-1-gerhard@engleder-embedded.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2021-12-14net_tstamp: add new flag HWTSTAMP_FLAG_BONDED_PHC_INDEXHangbin Liu1-3/+0
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 <kuba@kernel.org> Signed-off-by: Hangbin Liu <liuhangbin@gmail.com> Signed-off-by: David S.

2021-11-23tsnep: Fix set MAC addressGerhard Engleder1-1/+1
Commit 4dfb9982644b ("tsn: Fix build.") fixed compilation with const dev_addr. In tsnep_netdev_set_mac_address() the call of ether_addr_copy() was replaced with dev_set_mac_address(), which calls ndo_set_mac_address(). This results in an endless recursive loop because ndo_set_mac_address is set to tsnep_netdev_set_mac_address. Call eth_hw_addr_set() instead of dev_set_mac_address() in ndo_set_mac_address()/tsnep_netdev_set_mac_address() to copy the address as intended.
