This series contains updates to ice driver only.

Chinh adds retrying of sending some AQ commands when receiving EBUSY
error.

Victor modifies how nodes are added to reduce stack usage.

Ani renames some variables to either follow spec naming or to be inline
with naming in the rest of the driver. Ignores EMODE error as there are
cases where this error is expected. Performs some cleanup such as
removing unnecessary checks, doing variable assignments over copies, and
removing unneeded variables. Revises some error codes returned in link
settings to be more appropriate. He also implements support for new
firmware option to get default link configuration which accounts for
any needed NVM based overrides for PHY configuration. He also removes
the rx_gro_dropped stat as the value no longer changes.

Jeb removes setting specific link modes on firmwares that no longer
require it.

Brett removes unnecessary checks when adding and removing VLANs.

Tony fixes a checkpatch warning for unnecessary blank line.

The following are changes since commit 3cd52c1e32fe7dfee09815ced702db9ee9f84ec9:
  net: fealnx: use module_pci_driver to simplify the code
and are available in the git repository at:
  git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue 100GbE

From: Chinh T Cao <chinh.t.cao@intel.com>

Retry sending some AQ commands, as result of EBUSY AQ error.
ice_aqc_opc_get_link_topo
ice_aqc_opc_lldp_stop
ice_aqc_opc_lldp_start
ice_aqc_opc_lldp_filter_ctrl

This change follows the latest guidelines from HW team. It is
better to retry the same AQ command several times, as the result
of EBUSY, instead of returning error to the caller right away.

From: Victor Raj <victor.raj@intel.com>

Remove the recursive way of adding the nodes to the layer in order
to reduce the stack usage. Instead the algorithm is modified to use
a while loop.

The previous code was scanning recursively the nodes horizontally.
The total stack consumption will be based on number of nodes present
on that layer. In some cases it can consume more stack.

For get PHY abilities AQ, the specification defines "report modes"
as "with media", "without media" and "active configuration". For
clarity, rename macros to align with the specification.

From: Anirudh Venkataramanan <anirudh.venkataramanan@intel.com>

When link is owned by manageability, the driver is not allowed to fiddle
with link. FW returns ICE_AQ_RC_EMODE if the driver attempts to do so.
This patch adds a new function ice_set_link which abstracts the call to
ice_aq_set_link_restart_an and provides a clean way to turn on/off link.

While making this change, I also spotted that an int variable was being
used to hold both an ice_status return code and the Linux errno return
code. This pattern more often than not results in the driver inadvertently
returning ice_status back to kernel which is a major boo-boo. Clean it up.

The loop checking for PF VSI doesn't make any sense. The VSI type
backing the netdev passed to ice_set_link_ksettings will always be
of type ICE_PF_VSI. Remove it.

In ice_set_link_ksettings, change 'abilities' to 'phy_caps' and 'p' to
'pi'. This is more consistent with similar usages elsewhere in the
driver.

From: Anirudh Venkataramanan <anirudh.venkataramanan@intel.com>

Recent firmware supports a new "get PHY capabilities" mode
ICE_AQC_REPORT_DFLT_CFG which makes it unnecessary for the driver
to track and apply NVM based default link overrides.

If FW AQ API version supports it, use Report Default Configuration.
Add check function for Report Default Configuration support and update
accordingly.

Also change adv_phy_type_[lo|hi] to advert_phy_type[lo|hi] for
clarity.

From: Jeb Cramer <jeb.j.cramer@intel.com>

Beyond a specific version of firmware, there is no need to provide
override values to the firmware when setting PHY capabilities.  In this
case, we do not need to indicate whether we're in Strict or Lenient Link
Mode.

In the case of translating capabilities to the configuration structure,
the module compliance enforcement is already correctly set by firmware,
so the extra code block is redundant.

From: Brett Creeley <brett.creeley@intel.com>

Currently the driver is doing two unnecessary checks. First both ops are
checking if the VLAN ID passed in is less than VLAN_N_VID and second
both ops are checking to see if a port VLAN is configured on the VSI.

The first check is already handled by the 8021q driver so this is an
unnecessary check. The second check is unnecessary because the PF VSI is
never put into a port VLAN.

Remove these checks.
