2017-02-15mlxsw: acl: Use PBS type for forward actionJiri Pirko1-11/+9
Current behaviour of "mirred redirect" action (forward) offload is a bit odd. For matched packets the action forwards them to the desired destination, but it also lets the packet duplicates to go the original way down (bridge, router, etc). That is more like "mirred mirror". Fix this by using PBS type which behaves exactly like "mirred redirect". Note that PBS does not support loopback mode.

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.

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.
