eth: fbnic: Write the TCAM tables used for RSS control and Rx to host

RSS is controlled by the Rx filter tables. Program rules matching
on appropriate traffic types and set hashing fields using actions.
We need a separate set of rules for broadcast and multicast
because the action there needs to include forwarding to BMC.

This patch only initializes the default settings, the control
of the configuration using ethtool will come soon.

With this the necessary rules are put in place to enable Rx of packets by
the host.
