Fun set of conflict resolutions here... For the mac80211 stuff, these were fortunately just parallel adds. Trivially resolved. In drivers/net/phy/phy.c we had a bug fix in 'net' that moved the function phy_disable_interrupts() earlier in the file, whilst in 'net-next' the phy_error() call from this function was removed. In net/ipv4/xfrm4_policy.c, David Ahern's changes to remove the 'rt_table_id' member of rtable collided with a bug fix in 'net' that added a new struct member "rt_mtu_locked" which needs to be copied over here. The mlxsw driver conflict consisted of net-next separating the span code and definitions into separate files, whilst a 'net' bug fix made some changes to that moved code. The mlx5 infiniband conflict resolution was quite non-trivial, the RDMA tree's merge commit was used as a guide here, and here are their notes: ==================== Due to bug fixes found by the syzkaller bot and taken into the for-rc branch after development for the 4.17 merge window had already started being taken into the for-next branch, there were fairly non-trivial merge issues that would need to be resolved between the for-rc branch and the for-next branch. This merge resolves those conflicts and provides a unified base upon which ongoing development for 4.17 can be based. Conflicts: drivers/infiniband/hw/mlx5/main.c - Commit42cea83f95
(IB/mlx5: Fix cleanup order on unload) added to for-rc and commitb5ca15ad7e
(IB/mlx5: Add proper representors support) add as part of the devel cycle both needed to modify the init/de-init functions used by mlx5. To support the new representors, the new functions added by the cleanup patch needed to be made non-static, and the init/de-init list added by the representors patch needed to be modified to match the init/de-init list changes made by the cleanup patch. Updates: drivers/infiniband/hw/mlx5/mlx5_ib.h - Update function prototypes added by representors patch to reflect new function names as changed by cleanup patch drivers/infiniband/hw/mlx5/ib_rep.c - Update init/de-init stage list to match new order from cleanup patch ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

|

|
|
*
|

|

* PENDING: PHY device is coming up, but the ethernet driver is

|
* ready. phy_start will set this state if the PHY state is
|

* - PHY driver will set the state to UP when the PHY is ready

* UP: The PHY and attached device are ready to do work.

|
|
* - If autonegotiation finishes, but there's no link, it sets
|
|
* the state to NOLINK.
|

* - phy_stop moves to HALTED
|
|
*
|
|
* RUNNING: PHY is currently up, running, and possibly sending
|
|
* and/or receiving packets
|
|
* - timer will set CHANGELINK if we're polling (this ensures the
|
|
* link state is polled every other cycle of this state machine,
|
|
* which makes it every other second)
