Let the msk sendbuf track the size of the larger subflow's
send window, so that we ensure mptcp_sendmsg() does not
exceed MPTCP-level send window.

The update is performed just before try to send any data.

This is a prerequisite to allow receiving data from multiple
subflows without re-injection.

Instead of dropping the OoO - "future" data in
subflow_check_data_avail(), call into __mptcp_move_skbs()
and let the msk drop that.

To avoid code duplication factor out the mptcp_subflow_discard_data()
helper.

Note that __mptcp_move_skbs() can now find multiple subflows
with data avail (comprising to-be-discarded data), so must
update the byte counter incrementally.

v1 -> v2:
 - fix checkpatch issues (unsigned -> unsigned int)

Currently, when checking for the 'msk is writable' condition, we
look at the individual subflows write space.
That works well while we send data via a single subflow, but will
not as soon as we will enable concurrent xmit on multiple subflows.

With this change msk becomes writable when the following conditions
hold:
- the socket has some free write space
- there is at least a subflow with write free space

Additionally we need to set the NOSPACE bit on all subflows
before blocking.

ethernet: convert tasklets to use new tasklet_setup API

Commit 12cc923f ("tasklet: Introduce new initialization API")'
introduced a new tasklet initialization API. This series converts
all the crypto modules to use the new tasklet_setup() API

This series is based on v5.9-rc5

v3:
  fix subject prefix
  use backpointer instead of fragile priv to netdev.

v2:
  fix kdoc reported by Jakub Kicinski.

Richard Cochran points out that SKBTX_IN_PROGRESS should be set when
the skbuff is queued for timestamping.  Add this.

'w89c840_open()' is incorrectly reported in a debug message. Use __func__
instead.

While at it, fix some style issue in the same function.

The wrappers in include/linux/pci-dma-compat.h should go away.

The patch has been generated with the coccinelle script below and has been
hand modified to replace GFP_ with a correct flag.
It has been compile tested.

When memory is allocated in 'alloc_ringdesc()' GFP_KERNEL can be used
because it is only called from 'netdev_open()' which is a '.ndo_open'
function. Such functions are synchronized using the rtnl_lock() semaphore
and no lock is taken in the between.

The wrappers in include/linux/pci-dma-compat.h should go away.

The patch has been generated with the coccinelle script below and has been
hand modified to replace GFP_ with a correct flag.
It has been compile tested.

When memory is allocated in 'tlan_init()' GFP_KERNEL can be used because
it is only called from a probe function or a module_init function and no
lock is taken in the between.
The call chain is:
  tlan_probe                        (module_init function)
    --> tlan_eisa_probe
or
  tlan_init_one                     (probe function)

then in both cases:
    --> tlan_probe1
      --> tlan_init

We found a set but not used variable 'ring_cons' in mlx4_en_xmit(), it will
cause a warning when build the kernel. And after checking the commit record
of this function, we found that it was introduced by a previous patch.

So, We delete this redundant assignment code.
