2017-02-15mlx4: do not use rwlock in fast pathEric Dumazet2-18/+19
Using a reader-writer lock in fast path is silly, when we can instead use RCU or a seqlock. For mlx4 hwstamp clock, a seqlock is the way to go, removing two atomic operations and false sharing.

2017-02-14net: ethernet: ti: cpsw: use var instead of func for usage countIvan Khoronzhuk1-30/+12
The usage count function is based on ndev_running flag that is updated before calling ndo_open/close, but if ndo is called in another place, as with suspend/resume, the counter is not changed, that breaks sus/resume. For common resource no difference which device is using it, does matter only device count. So, replace usage count function on var and inc and dec it in ndo_open/close.

2017-02-14pcnet32: fix BNC/AUI port on AM79C970AOndrej Zary1-52/+125
Even though the port autoselection is enabled by default on AM79C970A, BNC/AUI port does not work because the link is always reported to be down. The link state reported by the chip belongs only to the TP port but the driver uses it regardless of the port used. The chip can't detect BNC/AUI link state. Disable port autoselection and use TP port by default to keep current behavior (link detection works on TP port, BNC/AUI port does not work). Implement ethtool autoneg, port and duplex configuration to allow using the BNC/AUI port. Report the TP link state only if the TP port is selected. When the port autoselection is enabled or AUI port is selected, report the link as always up. Move pcnet32_suspend() and pcnet32_clr_suspend() functions to avoid forward declarations.

2017-02-14ldmvsw: disable tso and gso for bridge operationsShannon Nelson2-4/+4
The ldmvsw driver is specifically for supporting the ldom virtual networking by running in the primary ldom and using the LDC to connect the remaining ldoms to the outside world via a bridge. With TSO and GSO supported while connected the bridge, things tend to misbehave as seen in our case by delayed packets, enough to begin triggering retransmits and affecting overall throughput. By turning off advertised support for TSO and GSO we restore stable traffic flow through the bridge. Orabug: 23293104 Signed-off-by: Shannon Nelson <shannon.nelson@oracle.com> Signed-off-by: David S.

2017-02-14sunvnet: make sunvnet common code dynamically loadableShannon Nelson2-2/+11
When the sunvnet_common code was split out for use by both sunvnet and the newer ldmvsw, it was made into a static kernel library, which limits the usefulness of sunvnet and ldmvsw as loadables, since most of the real work is being done in the shared code. Also, this is simply dead code in kernels that aren't running the LDoms. This patch makes the sunvnet_common into a dynamically loadable module and makes sunvnet and ldmvsw dependent on sunvnet_common.

2017-02-14bridge: fdb: converge fdb_delete_by functions into oneNikolay Aleksandrov1-47/+15

2017-02-14bridge: fdb: converge fdb searching functions into oneNikolay Aleksandrov4-70/+54
Before this patch we had 3 different fdb searching functions which was confusing. This patch reduces all of them to one - fdb_find_rcu(), and two flavors: br_fdb_find() which requires hash_lock and br_fdb_find_rcu which requires RCU. This makes it clear what needs to be used, we also remove two abusers of __br_fdb_get which called it under hash_lock and replace them with br_fdb_find().

2017-02-13net: dsa: mv88e6xxx: Add watchdog interrupt handlerAndrew Lunn4-1/+127
The switch contains a watchdog looking for issues with the internal gubbins of the switch. Hook the interrupt the watchdog triggers and log the value of the control register indicating why the watchdog fired. The watchdog can only be cleared with a switch reset, which will destroy the current configuration. Rather than doing this, just disable the interrupt. The mv88e6390 family has different watchdog registers. So use an ops structure, so support for the mv88e6390 family can be added later.
