Implement TSINFO_GET request to get timestamping information for a network
device. This is traditionally available via ETHTOOL_GET_TS_INFO ioctl
request.
Move part of ethtool_get_ts_info() into common.c so that ioctl and netlink
code use the same logic to get timestamping information from the device.
v3: use "TSINFO" rather than "TIMESTAMP", suggested by Richard Cochran

Add three string sets related to timestamping information:
ETH_SS_SOF_TIMESTAMPING: SOF_TIMESTAMPING_* flags
ETH_SS_TS_TX_TYPES: timestamping Tx types
ETH_SS_TS_RX_FILTERS: timestamping Rx filters
These will be used for TIMESTAMP_GET request.
v2: avoid compiler warning ("enumeration value not handled in switch")
in net_hwtstamp_validate()
v3: omit dash in Tx type names ("one-step-*" -> "onestep-*"), suggested by

Currently, ethtool feature mask for checksum command is ORed with
NETIF_F_FCOE_CRC_BIT, which is bit's position number, instead of the
actual feature bit - NETIF_F_FCOE_CRC.

Legacy ioctl request like ETHTOOL_GTXCSUM are still used by ethtool utility
to get values of legacy flags (which rather work as feature groups). These
are calculated from values of actual features and request to set them is
implemented as an attempt to set all features mapping to them but there are
two inconsistencies:
- tx-checksum-fcoe-crc is shown under tx-checksumming but NETIF_F_FCOE_CRC
is not included in ETHTOOL_GTXCSUM/ETHTOOL_STXCSUM
- tx-scatter-gather-fraglist is shown under scatter-gather but
NETIF_F_FRAGLIST is not included in ETHTOOL_GSG/ETHTOOL_SSG

view, fix ethtool_get_feature_mask() to match it.

Linux supports 22 different interrupt coalescing parameters.
No driver implements them all. Some drivers just ignore the
ones they don't support, while others have to carry a long
list of checks to reject unsupported settings.
To simplify the drivers add the ability to specify inside
ethtool_ops which parameters are supported and let the core
reject attempts to set any other one.
This commit makes the mechanism an opt-in, only drivers which
set ethtool_opts->coalesce_types to a non-zero value will have
the checks enforced.
The same mask is used for global and per queue settings.
v3: - move the (temporary) check if driver defines types
earlier (Michal)
- rename used_types -> nonzero_params, and
coalesce_types -> supported_coalesce_params (Alex)
- use EOPNOTSUPP instead of EINVAL (Andrew, Michal)
Leaving the long series of ifs for now, it seems nice to
be able to grep for the field and flag names. This will
probably have to be revisited once netlink support lands.

Syzbot reported that ethnl_compact_sanity_checks() can be tricked into
reading past the end of ETHTOOL_A_BITSET_VALUE and ETHTOOL_A_BITSET_MASK
attributes and even the message by passing a value between (u32)(-31)
and (u32)(-1) as ETHTOOL_A_BITSET_SIZE.
The problem is that DIV_ROUND_UP(attr_nbits, 32) is 0 for such values so
that zero length ETHTOOL_A_BITSET_VALUE will pass the length check but
ethnl_bitmap32_not_zero() check would try to access up to 512 MB of
attribute "payload".
Prevent this overflow byt limiting the bitset size. Technically, compact
bitset format would allow bitset sizes up to almost 2^18 (so that the
nest size does not exceed U16_MAX) but bitsets used by ethtool are much
shorter. S16_MAX, the largest value which can be directly used as an
upper limit in policy, should be a reasonable compromise.

A bitset without mask in a _SET request means we want exactly the bits in
the bitset to be set. This works correctly for compact format but when
verbose format is parsed, ethnl_update_bitset32_verbose() only sets the
bits present in the request bitset but does not clear the rest. This can
cause incorrect results like
lion:~ # ethtool eth0 | grep Wake
Supports Wake-on: pumbg
Wake-on: g
lion:~ # ethtool -s eth0 wol u
lion:~ # ethtool eth0 | grep Wake

In order to stop useless driver version bumps and unify output
presented by ethtool -i, let's set default version string.
As Linus said in [1]: "Things are supposed to be backwards and
forwards compatible, because we don't accept breakage in user
space anyway. So versioning is pointless, and only causes
problems."
They cause problems when users start to see version changes
and expect specific set of features which will be different
for stable@, vanilla and distribution kernels.
Distribution kernels are based on some kernel version with extra
patches on top, for example, in RedHat world this "extra" is a lot
and for them your driver version say nothing. Users who run vanilla
kernels won't use driver version information too, because running
such kernels requires knowledge and understanding.
Another set of problems are related to difference in versioning scheme
and such doesn't allow to write meaningful automation which will work
sanely on all ethtool capable devices.
Before this change:
[leonro@erver ~]$ ethtool -i eth0
driver: virtio_net
version: 1.0.0
After this change and once ->version assignment will be deleted
from virtio_net:
[leonro@server ~]$ ethtool -i eth0
driver: virtio_net
version: 5.5.0-rc6+
