Merge branch 'ethtool-copybreak'

Guangbin Huang says:

====================
ethtool: add support to set/get tx copybreak buf size and rx buf len

This series add support to set/get tx copybreak buf size and rx buf len via
ethtool and hns3 driver implements them.

Tx copybreak buf size is used for tx copybreak feature which for small size
packet or frag. Use ethtool --get-tunable command to get it, and ethtool
--set-tunable command to set it, examples are as follow:

1. set tx spare buf size to 102400:
$ ethtool --set-tunable eth1 tx-buf-size 102400

2. get tx spare buf size:
$ ethtool --get-tunable eth1 tx-buf-size
tx-buf-size: 102400

Rx buf len is buffer length of each rx BD. Use ethtool -g command to get
it, and ethtool -G command to set it, examples are as follow:

1. set rx buf len to 4096
$ ethtool -G eth1 rx-buf-len 4096

2. get rx buf len
$ ethtool -g eth1
...
RX Buf Len: 4096

Change log:
V5 -> V6
1.Fix compile error for divers/s390.

V4 -> V5
1.Change struct ethtool_ringparam_ext to kernel_ethtool_ringparam.
2.change "__u32 rx_buf_len" to "u32 rx_buf_len".

V3 -> V4
1.Fix a few allmodconfig compile warning.
2.Add more '=' synbol to ethtool-netlink.rst to refine format.
3.Move definement of struct ethtool_ringparam_ext to include/linux/ethtool.h.
4.Move related modify of rings_fill_reply() from patch 4/6 to patch 3/6.

V2 -> V3
1.Remove documentation for tx copybreak buf size, there is description for
it in userspace ethtool.
2.Move extending parameters for get/set_ringparam function from patch3/6
to patch 4/6.

V1 -> V2
1.Add documentation for rx buf len and tx copybreak buf size.
2.Extend structure ringparam_ext for extenal ring params.
3.Change type of ETHTOOL_A_RINGS_RX_BUF_LEN from NLA_U32 to
NLA_POLICY_MIN(NLA_U32, 1).
4.Add supported_ring_params in ethtool_ops to indicate if support external
params.

ethtool: extend coalesce setting uAPI with CQE mode

In order to support more coalesce parameters through netlink,
add two new parameter kernel_coal and extack for .set_coalesce
and .get_coalesce, then some extra info can return to user with
the netlink API.

Merge branch 'ndo_ioctl-rework'

Arnd Bergmann says:

====================
ndo_ioctl rework

This series is a follow-up to the series for removing
compat_alloc_user_space() and copy_in_user() that has now
been merged.

I wanted to be sure I address all the ways that 'struct ifreq' is used
in device drivers through .ndo_do_ioctl, originally to prove that
my approach of changing the struct definition was correct, but then
I discarded that approach and went on anyway.

Roughly, the contents here are:

- split out all the users of SIOCDEVPRIVATE ioctls into a
separate ndo_siocdevprivate callback, to better see what
gets used where

- fix compat handling for those drivers that pass data
directly inside of 'ifreq' rather than using an indirect
ifr_data pointer

- remove unreachable code in ndo_ioctl handlers that relies
on command codes we never pass into that, in particular
for wireless drivers

- split out the ethernet specific ioctls into yet another
ndo_eth_ioctl callback, as these are by far the most
common use of ndo_do_ioctl today. I considered splitting
them further into MII and timestamp controls, but
went with the simpler change for now.

- split out bonding and wandev ioctls into separate helpers

- rework the bridge handling with a separate callback

At this point, only a few oddball things remain in ndo_do_ioctl:
appletalk and ieee802154 pass down SIOCSIFADDR/SIOCGIFADDR and
some wireless drivers have completely dead code.

I have thoroughly compile tested this on randconfig builds,
but not done any notable runtime testing, so please review.
All of it is also available as part of a larger branch at

compat-alloc-user-space-12

Changes since v2:
- rebase to net-next
- fix qeth regression
- Cc driver maintainers for each patch and in cover letter

Changes since v1:

- rebase to linux-5.14-rc2
- add conversion for ndo_siowandev, bridge and bonding drivers
- leave broken wifi drivers untouched for now
