This patch consolidates the logic behind dynamically setting TXDCTL.WTHRESH
depending on interrupt throttle rate (ITR) setting regardless of BQL.
Previously TXDCTL.WTHRESH was dynamically being set only with BQL being
enabled, but we have to set it regardless of BQL when ITR is low to avoid
Tx stalls/hangs.

All other add functions for lists have the new item as first argument

for no good reason in this function and makes using it unnecessary
confusing.
The name was changed to hlist_add_behind() to cause unconverted code to

In cases where the driver is loaded while there are no SFP+ modules in
the cage the interface was not being detected as SFP capable. To account
for this the driver called identify_sfp in ixgbe_get_settings to make
sure the data is correct. However when there is no SFP+ module in the cage
the driver waits for the I2C reads to time out which can take more than a
second and will cause issues with tools (like net-snmp) that may poll
for that information.
This patch resolves the issue by identifying interfaces with no PHY
type set as SFP capable which allows the driver to detect the SFP module
when the interface is brought up. As result of this we can also remove the
identify_sfp call from ixgbe_get_settings.
v2: remove the 82599 specific check since we have 82598 devices that are SFP
capable.

This patch fixes several issues with the previous implementation of the
SFF data dump of SFP+ modules:
- removed the __IXGBE_READ_I2C flag - I2C access locking is handled in the
HW specific routines
- fixed the read loop to read data from ee->offset to ee->len
- the reads fail if __IXGBE_IN_SFP_INIT is set in the process - this is
needed because on some HW I2C operations can take long time and disrupt
the SFP and link detection process

I'm not sure why, but the hlist for each entry iterators were conceived
list_for_each_entry(pos, head, member)
The hlist ones were greedy and wanted an extra parameter:
hlist_for_each_entry(tpos, pos, head, member)
Why did they need an extra pos parameter? I'm not quite sure. Not only
they don't really need it, it also prevents the iterator from looking
exactly like the list iterator, which is unfortunate.
Besides the semantic patch, there was some manual work required:
- Fix up the actual hlist iterators in linux/list.h
- Fix up the declaration of other iterators based on the hlist ones.
- A very small amount of places were using the 'node' parameter, this
was modified to use 'obj->member' instead.
- Coccinelle didn't handle the hlist_for_each_entry_safe iterator
properly, so those had to be fixed up manually.

behind this change is due to reasoning that we do in fact support the

supported via the get_ts_info ioctl and which filters are in practice actually

This patch cleans up the ethtool diagnostics test by ensuring that the tests
work properly regardless of what state the adapter was in. The SRIOV VF check is
done at the beginning, forgoing the link test. The if_running -> dev_close is
moved before the link test, as well as a call to enable the Tx laser. This
ensures that the link test will return valid results even when adapter was
previously down. Also, a call to disable the Tx laser is added if the device
was down before the start. This ensures consistent behavior of the Tx laser
before and after the diagnostic checks. The end result is consistent behavior
regardless of device state.

Where a PTP clock driver is associated with a net or PHY driver, it
should be enabled automatically whenever that driver is enabled.
Therefore:
- Make PTP clock drivers select rather than depending on PTP_1588_CLOCK
- Remove separate boolean options for PTP clock drivers that are built
as part of net driver modules. (This also fixes cases where the PTP
subsystem is wrongly forced to be built-in.)
- Set 'default y' for PTP clock drivers that depend on specific net
drivers but are built separately

This patch corrects the ethtool get_ts_info functon which did not state that
software timestamping was supported, even though it is.

We were not correctly freeing the temporary rings on error in
ixgbe_set_ring_param. In order to correct this I am unwinding a number of
changes that were made in order to get things back to the original working
form with modification for the current ring layouts.
This approach has multiple advantages including a smaller memory footprint,
and the fact that the interface is stopped while we are allocating the rings
meaning that there is less potential for some sort of memory corruption on the
ring.
The only disadvantage I see with this approach is that on a Rx allocation
failure we will report an error and only update the Tx rings. However the
adapter should be fully functional in this state and the likelihood of such
an error is very low. In addition it is not unreasonable to expect the
user to need to recheck the ring configuration should they experience an
error setting the ring sizes.

This patch fixes a development issue that occurred due to invalid modes reported
in the ethtool get_ts_info function. The issue is resolved by removing
unsupported modes from the Rx supported list.
