Subject: [Intel-wired-lan] [PATCH iwl-net] i40e: Fix unexpected MFS warning message
Date: Fri, 10 Nov 2023 09:12:09 +0100	[thread overview]
Message-ID: <20231110081209.189481-1-ivecera@redhat.com> (raw)

Commit 3a2c6ced90e1 ("i40e: Add a check to see if MFS is set") added
a warning message that reports unexpected size of port's MFS (max
frame size) value. This message use for the port number local
variable 'i' that is wrong.
In i40e_probe() this 'i' variable is used only to iterate VSIs
to find FDIR VSI:

<code>
...
/* if FDIR VSI was set up, start it now */
        for (i = 0; i < pf->num_alloc_vsi; i++) {
                if (pf->vsi[i] && pf->vsi[i]->type == I40E_VSI_FDIR) {
                        i40e_vsi_open(pf->vsi[i]);
                        break;
                }
        }
...
</code>

So the warning message use for the port number indext of FDIR VSI
if this exists or pf->num_alloc_vsi if not.

Fix the message by using 'pf->hw.port' for the port number.
