2015-05-13net: sched: use counter to break reclassify loopsFlorian Westphal5-30/+5
Seems all we want here is to avoid endless 'goto reclassify' loop. tc_classify_compat even resets this counter when something other than TC_ACT_RECLASSIFY is returned, so this skb-counter doesn't break hypothetical loops induced by something other than perpetual TC_ACT_RECLASSIFY return values. skb_act_clone is now identical to skb_clone, so just use that.

2015-05-12net: phy: micrel: Fix regression in kszphy_probeNiklas Cassel1-1/+2
Don't do clock-mode-select if clk == NULL, since when building without CONFIG_HAVE_CLK, clk_get returns NULL and clk_get_rate returns 0. Doing clock-mode-select in this cause causes kszphy_probe to return -EINVAL and thus prevents the device from being probed. The original code (before regression) would return 0 when building without CONFIG_HAVE_CLK.

From man page for bridge link set cmd: self link setting is configured on specified physical device master link setting is configured on the software bridge (default) The link setting has two values: the device-side value and the software bridge-side value. These are independent and settable using the bridge link set cmd by specifying some combination of [master] | [self]. Furthermore, the device-side and bridge-side settings have their own initial value, viewable from bridge -d link show cmd. Restoring br_setlink back to original makes rocker (the only in-kernel user of SELF link settings) work as first implement: two-sided values. It's true that when both MASTER and SELF are specified from the command, two netlink notifications are generated, one for each side of the settings.

Add new switchdev_port_bridge_setlink that can be used by drivers implementing .ndo_bridge_setlink to set switchdev bridge attributes. Basically turn the raw rtnl_bridge_setlink netlink into switchdev attr sets. Proper netlink attr policy checking is done on the protinfo part of the netlink msg. Currently, for protinfo, only bridge port attrs BR_LEARNING and BR_LEARNING_SYNC are parsed and passed to port driver. For afspec, VLAN objs are passed so switchdev driver can set VLANs assigned to SELF. To illustrate with iproute2 cmd, we have: bridge vlan add vid 10 dev sw1p1 self master To add VLAN 10 to port sw1p1 for both the bridge (master) and the device (self).
