cbdc666f3e RDMA/ipoib: Remove check for ETH_SS_TEST
The default action for unlisted tests is "not-supported", so given that
ipoib doesn't support ETH_SS_TEST, there is no need to check for it
in the case statements, just let it get caught by the default: case.

$ ethtool mlx4_ib0 | grep Link
	Link detected: yes
$ ip l set dev mlx4_ib0 down
$ ethtool mlx4_ib0 | grep Link

26e551c5ae RDMA: Fix return code check in rdma_set_cq_moderation
The proper return code is "-EOPNOTSUPP" when the modify_cq() callback is
not supported, all drivers should generate this and all users should check
for it when detecting not supported functionality.

4190b4e969 RDMA/core: Rename kernel modify_cq to better describe its usage
Current ib_modify_cq() is used to set CQ moderation parameters.

This patch renames ib_modify_cq() to be rdma_set_cq_moderation(),
because the kernel version of RDMA API doesn't need to follow already
exposed to user's API pattern (create_XXX/modify_XXX/query_XXX/destroy_XXX)
and better to have more accurate name which describes the actual usage.

9abb0d1bbd RDMA: Simplify get firmware interface
There is a need to forward FW version to user space
application through RDMA netlink. In order to make it safe, there
is need to declare nla_policy and limit the size of FW string.

The new define IB_FW_VERSION_NAME_MAX will limit the size of
FW version string. That define was chosen to be equal to
ETHTOOL_FWVERS_LEN, because many drivers anyway are limited
by that value indirectly.

The introduction of this define allows us to remove the string size
from get_fw_str function signature.

8c490669de RDMA/IPoIB: Replace netdev_priv with ipoib_priv for ipoib_get_link_ksettings
ipoib_dev_init accesses the wrong private data for the IPoIB device.
Commit cd565b4b51 (IB/IPoIB: Support acceleration options callbacks)
changed ipoib_priv from being identical to netdev_priv to being an
area inside of, but not the same pointer as, the netdev_priv pointer.
As such, the struct we want is the ipoib_priv area, not the netdev_priv
area, so use the right accessor, otherwise we kernel panic.

7ad24ea4bf net: get rid of SET_ETHTOOL_OPS
net: get rid of SET_ETHTOOL_OPS

Dave Miller mentioned he'd like to see SET_ETHTOOL_OPS gone.
This does that.

Mostly done via coccinelle script:
@@
struct ethtool_ops *ops;
struct net_device *dev;
@@
-       SET_ETHTOOL_OPS(dev, ops);
+       dev->ethtool_ops = ops;

Compile tested only, but I'd seriously wonder if this broke anything.

As a first step in moving from LRO to GRO, revert commit af40da894e
("IPoIB: add LRO support").  Also eliminate the ethtool set_flags
callback which isn't needed anymore.  Finally, we need to include
<linux/sched.h> directly to get the declaration of restart_syscall()
(which used to be included implicitly through <linux/inet_lro.h>).

This can be used to tune at run time the parameters controlling the
event (interrupt) generation rate and thus reduce the overhead
incurred by handling interrupts resulting in better throughput.  Since
IPoIB uses a single CQ for both RX and TX, RX is chosen to dictate
