switchdev: respect SKIP_EOPNOTSUPP flag in case there is no recursion

2015-11-03T18:39:21+00:00

Caller passing down the SKIP_EOPNOTSUPP switchdev flag expects that
-EOPNOTSUPP cannot be returned. But in case of direct op call without
recurtion, this may happen. So fix this by checking it always on the
end of __switchdev_port_attr_set function.

switchdev: fix: erasing too much of vlan obj when handling multiple vlan specs

2015-10-30T11:23:35+00:00

When adding vlans with multiple IFLA_BRIDGE_VLAN_INFO attrs set in AFSPEC,
we would wipe the vlan obj struct after the first IFLA_BRIDGE_VLAN_INFO.
Fix this by only clearing what's necessary on each IFLA_BRIDGE_VLAN_INFO
iteration.

switchdev: Add support for flood control

2015-10-30T03:26:38+00:00

Allow devices supporting this feature to control the flooding of unknown
unicast traffic, by making switchdev infrastructure propagate this setting
to the switch driver.

Conflicts:
	drivers/net/usb/asix_common.c
	net/ipv4/inet_connection_sock.c
	net/switchdev/switchdev.c

In the inet_connection_sock.c case the request socket hashing scheme
is completely different in net-next.

The other two conflicts were overlapping changes.

switchdev: assert rtnl mutex when going over lower netdevs

2015-10-15T13:09:53+00:00

netdev_for_each_lower_dev has to be called with rtnl mutex held. So
better enforce it in switchdev functions.

switchdev: introduce possibility to defer obj_add/del

2015-10-15T13:09:49+00:00

Similar to the attr usecase, the caller knows if he is holding RTNL and is
in atomic section. So let the called to decide the correct call variant.

This allows drivers to sleep inside their ops and wait for hw to get the
operation status. Then the status is propagated into switchdev core.
This avoids silent errors in drivers.

switchdev: remove pointers from switchdev objects

2015-10-15T13:09:49+00:00

When object is used in deferred work, we cannot use pointers in
switchdev object structures because the memory they point at may be already
used by someone else. So rather do local copy of the value.

switchdev: allow caller to explicitly request attr_set as deferred

2015-10-15T13:09:48+00:00

Caller should know if he can call attr_set directly (when holding RTNL)
or if he has to defer the att_set processing for later.

This also allows drivers to sleep inside attr_set and report operation
status back to switchdev core. Switchdev core then warns if status is
not ok, instead of silent errors happening in drivers.

Benefit from newly introduced switchdev deferred ops infrastructure.
