2018-03-30nfp: flower: offload phys port MTU changeJohn Hurley
Trigger a port mod message to request an MTU change on the NIC when any physical port representor is assigned a new MTU value. The driver waits 10 msec for an ack that the FW has set the MTU. If no ack is received the request is rejected and an appropriate warning flagged. Rather than maintain an MTU queue per repr, one is maintained per app. Because the MTU ndo is protected by the rtnl lock, there can never be contention here. Portmod messages from the NIC are also protected by rtnl so we first check if the portmod is an ack and, if so, handle outside rtnl and the cmsg work queue. Acks are detected by the marking of a bit in a portmod response. They are then verfied by checking the port number and MTU value expected by the app. If the expected MTU is 0 then no acks are currently expected. Also, ensure that the packet headroom reserved by the flower firmware is considered when accepting an MTU change on any repr.

2018-03-30nfp: modify app MTU setting callbacksJohn Hurley
Rename the 'change_mtu' app callback to 'check_mtu'. This is called whenever an MTU change is requested on a netdev. It can reject the change but is not responsible for implementing it. Introduce a new 'repr_change_mtu' app callback that is hit when the MTU of a repr is to be changed. This is responsible for performing the MTU change and verifying it.

2018-03-30net: phy: phylink: Provide PHY interface to mac_link_{up, down}Florian Fainelli
In preparation for having DSA transition entirely to PHYLINK, we need to pass a PHY interface type to the mac_link_{up,down} callbacks because we may have to make decisions on that (e.g: turn on/off RGMII interfaces etc.). We do not pass an entire phylink_link_state because not all parameters (pause, duplex etc.) are defined when the link is down, only link and interface are. Update mvneta accordingly since it currently implements phylink_mac_ops.

Florian Fainelli says: ==================== net: Broadcom drivers coalescing fixes Following Tal's review of the adaptive RX/TX coalescing feature added to the SYSTEMPORT and GENET driver a number of things showed up: - adaptive TX coalescing is not actually a good idea with the current way the estimator will program the ring, this results in a higher CPU load, NAPI on TX already does a reasonably good job at maintaining the interrupt count low - both SYSTEMPORT and GENET would suffer from the same issues while configuring coalescing parameters where the values would just not be applied correctly based on user settings, so we fix that too Tal, thanks again for your feedback, I would appreciate if you could review that the new behavior appears to be implemented correctly. Thanks! Changes in v2: - added Tal's reviewed-by to the first patch - split DIM initialization from coalescing parameters initialization - avoid duplicating the same code in bcmgenet_set_coalesce() when configuring RX rings - fixed the condition where default DIM parameters would be applied when adaptive RX coalescing would be enabled, do this only if it was disabled before ==================== Signed-off-by: David S.

2018-03-30net: Call add/kill vid ndo on vlan filter feature togglingGal Pressman
NETIF_F_HW_VLAN_[CS]TAG_FILTER features require more than just a bit flip in dev->features in order to keep the driver in a consistent state. These features notify the driver of each added/removed vlan, but toggling of vlan-filter does not notify the driver accordingly for each of the existing vlans. This patch implements a similar solution to NETIF_F_RX_UDP_TUNNEL_PORT behavior (which notifies the driver about UDP ports in the same manner that vids are reported). Each toggling of the features propagates to the 8021q module, which iterates over the vlans and call add/kill ndo accordingly.

dm_get_bdev_for_ioctl()'s return of 0 or 1 must be the result from prepare_ioctl (1 means the ioctl was issued to a partition, 0 means it wasn't). Unfortunately commit 519049afea ("dm: use blkdev_get rather than bdgrab when issuing pass-through ioctl") reused the variable 'r' to store the return from blkdev_get() that follows prepare_ioctl() -- whereby dropping prepare_ioctl()'s result on the floor. This can lead to an ioctl or persistent reservation being issued to a partition going unnoticed, which implies the extra permission check for CAP_SYS_RAWIO is skipped. Fix this by using a different variable to store blkdev_get()'s return.
