Subject: [PATCH net-next 01/15] ice: rename switchdev to eswitch

From: Michal Swiatkowski <michal.swiatkowski@...ux.intel.com>

Eswitch is used as a prefix for related functions. Main structure
storing all data related to eswitch should also be named as eswitch
instead of ice_switchdev_info. Rename it.

Also rename switchdev to eswitch where the context is not about eswitch
mode.

::uplink_netdev was changed to netdev for simplicity. There is no other
netdev in function scope so it is obvious.
