This patch allow users to dump content of NCL_CONFIG by using debugfs
command.
Command format:
	echo dump ncl_config <offset> <length> > cmd
It will print as follows:

	hns3 0000:7d:00.0: 0x0000 | 0x00000020

Currently when calculating how much to increment ITR by inside of
ice_update_itr() we do some estimations and intermediate
calculations. Instead of doing estimations, just do the
calculation directly. This allows for a more accurate value and it
makes it easier for the next person to understand and update.

Also, remove the dividing the ITR value by 2 when latency
driven because the ITR values are already so low for 100Gbps
speed. This should help get to the desired ITR value faster.

This patch adds a new function ice_pf_dcb_cfg (and related helpers)
which applies the DCB configuration obtained from the firmware. As
part of this, VSIs/netdevs are updated with traffic class information.

This patch requires a bit of a refactor of existing code.

1. For a MIB change event, the associated VSI is closed and brought up
   again. The gap between closing and opening the VSI can cause a race
   condition. Fix this by grabbing the rtnl_lock prior to closing the
   VSI and then only free it after re-opening the VSI during a MIB
   change event.

2. ice_sched_query_elem is used in ice_sched.c and with this patch, in
   ice_dcb.c as well. However, ice_dcb.c is not built when CONFIG_DCB is
   unset. This results in namespace warnings (ice_sched.o: Externally
   defined symbols with no external references) when CONFIG_DCB is unset.
   To avoid this move ice_sched_query_elem from ice_sched.c to
   ice_common.c.

On platforms that lack a TCAM (like LS1088A), masking of
flow steering keys is not supported. Until now we didn't
offer flow steering capabilities at all on these platforms,
since our driver implementation configured a "comprehensive"
FS key (containing all supported header fields), with masks
used to ignore the fields not present in the rules provided
by the user.

We now allow ethtool rules that share a common key (i.e. have
the same header fields). The FS key is now kept in the driver
private data and initialized when the first rule is added to
an empty table, rather than at probe time. If a rule with a new
composition key is wanted, the user must first manually delete
all previous rules.

When building a FS table entry to pass to firmware, we still use
the old building algorithm, which assumes an all-supported-fields
key, and later collapse the fields which aren't actually needed.

Masked rules are not supported; if provided, the mask value
will be ignored. For firmware versions older than MC10.7.0
(that only offer the legacy ABIs for configuring distribution
keys) flow steering without masking support remains unavailable.
