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

This patch introduces a new top level function ice_init_dcb (and
related lower level helper functions) which continues the DCB init
flow.
This function uses ice_get_dcb_cfg to get, parse and store the DCB
configuration. Once this is done, it sets itself up to be noti
This series contains updates to the ice driver only.
Anirudh fixes up code comments which had typos. Added support for DCB
into the ice driver, which required a bit of refactoring of the existing
code. Also fixed a potential race condition between closing and opening
the VSI for a MIB change eve

Currently the model of netdevsim is a bit odd in multiple ways.
1) devlink instance is not in any way related with actual netdevsim
netdevices. Instead, it is created per-namespace.
2) multi-port netdevsim device is done using "link" attribute.
3) netdevsim bus is there only t

These functions are going to be called from bus probe/release(),
therefore make them independent on ns struct and rename accordingly.

Current implementation of parent_id/switch_id does not follow the
original idea of being unique. The values are "0", "1", etc. Instead of
that, generate 32 random bytes.
