ice: Add support for switch filter programming
A VSI needs traffic directed towards it. This is done by programming filter rules on the switch (embedded vSwitch) element in the hardware, which connects the VSI to the ingress/egress port. This patch introduces data structures and functions necessary to add remove or update switch rules on the switch element. This is a pretty low level function that is generic enough to add a whole range of filters. This patch also introduces two top level functions ice_add_mac and ice_remove mac which through a series of intermediate helper functions eventually call ice_aq_sw_rules to add/delete simple MAC based filters. It's worth noting that one invocation of ice_add_mac/ice_remove_mac is capable of adding/deleting multiple MAC filters. Also worth noting is the fact that the driver maintains a list of currently active filters, so every filter addition/removal causes an update to this list. This is done for a couple of reasons: 1) If two VSIs try to add the same filters, we need to detect it and do things a little differently (i.e. use VSI lists, described below) as the same filter can't be added more than once. 2) In the event of a hardware reset we can simply walk through this list and restore the filters. VSI Lists: In a multi-VSI situation, it's possible that multiple VSIs want to add the same filter rule. For example, two VSIs that want to receive broadcast traffic would both add a filter for destination MAC ff:ff:ff:ff:ff:ff. This can become cumbersome to maintain and so this is handled using a VSI list. A VSI list is resource that can be allocated in the hardware using the ice_aq_alloc_free_res admin queue command. Simply put, a VSI list can be thought of as a subscription list containing a set of VSIs to which the packet should be forwarded, should the filter match. For example, if VSI-0 has already added a broadcast filter, and VSI-1 wants to do the same thing, the filter creation flow will detect this, allocate a VSI list and update the switch rule so that broadcast traffic will now be forwarded to the VSI list which contains VSI-0 and VSI-1.
