Prevent TIPC from incorrectly setting returned flags to poll()
in the following cases:

After commit 24b36f019 (netfilter: {ip,ip6,arp}_tables: dont block
bottom half more than necessary), lockdep can raise a warning
because we attempt to lock a spinlock with BH enabled, while
the same lock is usually locked by another cpu in a softirq context.
Disable again BH to avoid these lockdep warnings.

The driver name and bus address for a net_device can normally be found
through the driver model now. Instead of requiring drivers to provide
this information redundantly through the ethtool_ops::get_drvinfo
operation, use the driver model to do so if the driver does not define
the operation. Since ETHTOOL_GDRVINFO no longer requires the driver
to implement any operations, do not require net_device::ethtool_ops to
be set either.
Remove implementations of get_drvinfo and ethtool_ops that provide
only this information.

Factor out flow calculation code from get_rps_cpu, since other

Revisions:
v2 (Ben): Separate flow calcuation out and use in select queue.
v3 (Arnd): Don't re-implement MIN.
v4 (Changli): skb->data points to ethernet header in macvtap, and
make a fast path. Tested macvtap with this patch.
v5 (Changli):
- Cache skb->rxhash in skb_get_rxhash
- macvtap may not have pow(2) queues, so change code for
queue selection.
(Arnd):
- Use first available queue if all fails.

This patch introduces a new timer, which will release
queued-up MPDUs from the reorder buffer, whenever
they've waited for more than HT_RX_REORDER_BUF_TIMEOUT
(which is at around 100 ms).
The advantage of having a dedicated timer, instead of
relying on a constant stream of freshly arriving aMPDUs
to release the old ones, is particularly observable when
even a small fraction of MPDUs are forever lost at
low network speeds.
Previously under these circumstances frames would become
stuck in the reorder buffer and the network stack of both
HT peers throttled back, instead of revving up and
gunning the pipes.

When running in client mode and associating to an AP, the channel
change is usually performed with the offchannel flag still set.
However after the assoc is complete, the following channel change event
is suppressed because the run time channel is already set to the operating channel.

This patch implement basic infrastructure to support use of NAPI by
mac80211-based hardware drivers.
Because mac80211 devices can support multiple netdevs, a dummy netdev
is used for interfacing with the NAPI code in the core of the network
stack. That structure is hidden from the hardware drivers, but the
actual napi_struct is exposed in the ieee80211_hw structure so that the
poll routines in drivers can retrieve that structure. Hardware drivers
can also specify their own weight value for NAPI polling.

refers to packet size and ip6_rt_fc_elasticity is used as scaler as in

This patch adds a limit for nframes as the number of frames in TX_SETUP and
RX_SETUP are derived from a single byte multiplex value by default.
Use-cases that would require to send/filter more than 256 CAN frames should
be implemented in userspace for complexity reasons anyway.
Additionally the assignments of unsigned values from userspace to signed
values in kernelspace and vice versa are fixed by using unsigned values in
kernelspace consistently.

If the DNS server returns an error, allow that to be cached in the DNS resolver
key in lieu of a value. Userspace passes the desired error number as an option
in the payload:
"#dnserror=<number>"
Userspace must map h_errno from the name resolution routines to an appropriate
Linux error before passing it up. Something like the following mapping is
recommended:
[HOST_NOT_FOUND] = ENODATA,
[TRY_AGAIN] = EAGAIN,
[NO_RECOVERY] = ECONNREFUSED,
[NO_DATA] = ENODATA,
in lieu of Linux errors specifically for representing name service errors. The
filesystem must map these errors appropropriately before passing them to
userspace. AFS is made to map ENODATA and EAGAIN to EDESTADDRREQ for the
return to userspace; ECONNREFUSED is allowed to stand as is.
The error can be seen in /proc/keys as a negative number after the description
of the key. Compare, for example, the following key entries:
2f97238c I--Q-- 1 53s 3f010000 0 0 dns_resol afsdb:grand.centrall.org: -61
338bfbbe I--Q-- 1 59m 3f010000 0 0 dns_resol afsdb:grand.central.org: 37
If the error option is supplied in the payload, the main part of the payload is
discarded. The key should have an expiry time set by userspace.

This is more kernel-ish, saves some space, and also allows us to
expand the ops without breaking all the callers who are happy for the
new members to be NULL.
The few places which defined their own param types are changed to the
new scheme (more which crept in recently fixed in following patches).
Since we're touching them anyway, we change get() and set() to take a
const struct kernel_param (which they really are). This causes some
harmless warnings until we fix them (in following patches).
To reduce churn, module_param_call creates the ops struct so the callers
don't have to change (and casts the functions to reduce warnings).
The modern version which takes an ops struct is called module_param_cb.
