[PATCH] i40e: print correct hw max rss count in kernel ring buffer

[Suresh Kumar]

The value printed for  "HW max RSS count" is wrong in kernel dmesg for i40e
NICs:

  ... i40e 0000:63:00.0: User requested queue count/HW max RSS count: 48/64

whereas  ethtool reports the correct value from "vsi->num_queue_pairs"

Channel parameters for eno33:
Pre-set maximums:
RX:     n/a
TX:     n/a
Other:      1
Combined:   96
Current hardware settings:
RX:     n/a
TX:     n/a
Other:      1
Combined:   96  <-------

and is misleading.

This value is printed from 'pf->rss_size_max' which seems hardcoded.

Below commit also removed this 64 limit:
