Subject: qed/qede: Add setter APIs support for RX flow classification

This patch adds support for adding and deleting rx flow
classification rules. Using this user can classify RX flow
constituting of TCP/UDP 4-tuples [src_ip/dst_ip and src_port/dst_port]
to be steered on a given RX queue

From: Rahul Verma <Rahul.Verma@cavium.com>

Subject: qed: Read per queue coalesce from hardware

Retrieve the actual coalesce value from hardware for every Rx/Tx
queue, instead of Rx/Tx coalesce value cached during set coalesce.
