This patch is to add hardware timestamping support
for ENETC. On Rx, timestamping is enabled for all
frames. On Tx, we only instruct the hardware to
timestamp the frames marked accordingly by the stack.
Because the RX BD ring dynamic allocation has not been
supported and it is too expensive to use extended RX BDs
if timestamping is not used, a Kconfig option is used to
enable extended RX BDs in order to support hardware
timestamping. This option will be removed once RX BD
ring dynamic allocation is implemented.

100GbE Intel Wired LAN Driver Updates 2019-05-23
This series contains updates to ice driver only.
Anirudh cleans up white space issues and other code formatting issues in the
driver. Also implemented LLDP persistence across reboots and start/stop of the
LLDP agent. Updated print statements for driver capabilities to include
if it is a device or function capability.
Bruce cleaned up variable declarations by removing unneeded assignment.
Dave fixes a potential hang due to a couple of flows that recursively
acquire the RTNL lock which results in a deadlock.
Tony updates the driver to advertise what link modes we are capable of
when the user does not request a specific link mode.
Usha fixes up the LLDP MIB change event handling by cleaning up
workarounds and print the DCB configuration changes detected.
Brett fixes the driver to handle failures in the VF reset path, which
was failing to free resources upon an error.
Richard fixed the reported of stats via ethtool to align with our other
Intel drivers.
Jesse optimizes the transmit buffer and ring structures to have more
efficient ordering to get hot cache lines to have packed data. Also
optimized the VF structure to use less memory, since it is used hundreds
of times throughout the driver.

Currently the driver is calling ice_napi_del() and then
unregister_netdev(). The call to unregister_netdev() will result in a
call to ice_stop() and then ice_vsi_close(). This is where we call
napi_disable() for all the MSI-X vectors. This flow is reversed so make
the changes to ensure napi_disable() happens prior to napi_del().
Before calling napi_del() and free_netdev() make sure
unregister_netdev() was called. This is done by making sure the
__ICE_DOWN bit is set in the vsi->state for the interested VSI.

This reverts commit f8b9958534.
The reverted change instructed the QMan hardware block to fetch
RX frame annotation and beginning of frame data to cache before
the core would read them.
It turns out that in rare cases, it's possible that a QMan
stashing transaction is delayed long enough such that, by the time
it gets executed, the frame in question had already been dequeued
by the core and software processing began on it. If the core
manages to unmap the frame buffer _before_ the stashing transaction
is executed, an SMMU exception will be raised.
Unfortunately there is no easy way to work around this while keeping
the performance advantages brought by QMan stashing, so disable
it altogether.

With .ndo_set_rx_mode/temac_set_multicast_list() being called in atomic

to access temac indirect registers, the mutex used to synchronize indirect
register is a no-no.
Replace it with a spinlock, and avoid sleeping in
temac_indirect_busywait().
To avoid excessive holding of the lock, which is now a spinlock, the
temac_device_reset() function is changed to only hold the lock for short
periods. With timeouts, it could be holding the spinlock for more than

When making configuration changes, the driver calls bnxt_close_nic()

irq_re_init is passed to the call sequence to indicate if IRQ

be included in the bnxt_reserve_rings() call. bnxt_reserve_rings()
can only call pci_disable_msix() if the irq_re_init parameter is
true, otherwise it may hit BUG() because some IRQs may not have been
freed yet.

For every RX packet, the driver replenishes all buffers used for that
packet and puts them back into the RX ring and RX aggregation ring.
In one code path where the RX packet has one RX buffer and one or more
aggregation buffers, we missed recycling the aggregation buffer(s) if
we are unable to allocate a new SKB buffer. This leads to the
aggregation ring slowly running out of buffers over time. Fix it
by properly recycling the aggregation buffers.

Now that there is a link mode for 100BaseT1, use it in
phy_basic_t1_features so T1 PHY drivers will indicate this mode via
the Ethtool API.
