no longer use pci_restore_state() at all (and that caused trivial
conflicts with the "make pci_restore_state return void" patch)

pci_restore_state only ever returns 0, thus there is no benefit in
having it return any value.  Also, a large majority of the callers do
not check the return code of pci_restore_state.  Make the
pci_restore_state a void return and avoid the overhead.

Various drivers are using implementations of ethtool_ops::get_link
that are equivalent to the default ethtool_op_get_link().  Change
them to use that instead.

<title>sfc: Remove ancient support for nesting of TX stop</title>

<id>c04bfc6b223662c42a77727342c1df7d39e686a2</id>
<content type='text'>
Long before this driver went into mainline, it had support for
multiple TX queues per port, with lockless TX enabled.  Since Linux
did not know anything of this, filling up any hardware TX queue would
stop the core TX queue and multiple hardware TX queues could fill up
before the scheduler reacted.  Thus it was necessary to keep a count
of how many TX queues were stopped and to wake the core TX queue only
when all had free space again.

The driver also previously (ab)used the per-hardware-queue stopped
flag as a counter to deal with various things that can inhibit TX, but
it no longer does that.

Remove the per-channel tx_stop_count, tx_stop_lock and
per-hardware-queue stopped count and just use the networking core
queue state directly.
