pf->rss_size_max is hardcoded and always prints max rss count as 64.

Eg:
  kernel: i40e 0000:af:00.1: User requested queue count/HW max RSS count:  104/64

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:   104
Current hardware settings:
RX:     n/a
TX:     n/a
Other:      1
Combined:   104  <-------

and is misleading.

Change it to vsi->num_queue_pairs

Hi Suresh,

following-up on our earlier emails.

I do think that if this it is a fix it should have a fixes tag.
Which should be for the commit where the bug was first visible to users.
