a trans_start struct member exists twice:
- in struct net_device (legacy)
- in struct netdev_queue
Instead of open-coding dev->trans_start usage to obtain the current
trans_start value, use dev_trans_start() instead.
This is not exactly the same, as dev_trans_start also considers
the trans_start values of the netdev queues owned by the device
and provides the most recent one.
For legacy devices this doesn't matter as dev_trans_start can cope
with netdev trans_start values of 0 (they are ignored).
This is a prerequisite to eventual removal of dev->trans_start.

ether_setup sets IFF_TX_SKB_SHARING but this is not supported by
qca_spi as it modifies the skb on xmit.

Currently qcaspi_netdev_setup accidentally clears IFF_BROADCAST.
So fix this by keeping the flags from ether_setup.

In case of a tx queue timeout every transmit is blocked until the
QCA7000 resets himself and triggers a sync which makes the driver
flushs the tx ring. So avoid this blocking situation by triggering
the sync immediately after the timeout. Waking the queue doesn't
make sense in this situation.

An spi_driver does not need to set an owner, it will be populated by the

This howto made sense in the 1990s when users had to manually configure
ISA cards with jumpers or vendor utilities, but with the implementation
of PCI it became increasingly less and less relevant, to the point where
it has been well over a decade since I last updated it. And there is
no value in anyone else taking over updating it either.
However the references to it continue to spread as boiler plate text
from one Kconfig file into the next. We are not doing end users any
favours by pointing them at this old document, so lets kill it with
fire, once and for all, to hopefully stop any further spread.
No code is changed in this commit, just Kconfig help text.

Four minor merge conflicts:
1) qca_spi.c renamed the local variable used for the SPI device
from spi_device to spi, meanwhile the spi_set_drvdata() call
got moved further up in the probe function.
2) Two changes were both adding new members to codel params
structure, and thus we had overlapping changes to the
initializer function.
3) 'net' was making a fix to sk_release_kernel() which is
completely removed in 'net-next'.
4) In net_namespace.c, the rtnl_net_fill() call for GET operations
had the command value fixed, meanwhile 'net-next' adjusted the
argument signature a bit.
This also matches example merge resolutions posted by Stephen
Rothwell over the past two days.

Registering the netdev before setting the priv data is unsafe.
So fix this possible race by setting the priv data first.

There is no need to call ether_setup after alloc_ethdev since it was
already called there.
Follow commits c706471b26 ("net: axienet: remove unnecessary
ether_setup after alloc_etherdev") and 3c87dcbfb3 ("net: ll_temac:
Remove unnecessary ether_setup after alloc_etherdev") and fix the
