[PATCH] net/ixgbe: fix port mask default value on E610

[PATCH] net/ixgbe: fix port mask default value on E610

[Yuan Wang]

Modification of default values should be limited to E610,
as 82599 handles raw IP well.

Hi,

I think you could do with clarifying the issue here. The patch title seems to
imply that there is an issue with the E610, but in fact the code change is
for all NICs except E610. What is the observed behaviour on an X550 or an
82599 NIC vs what is desired? Is setting the default masks to zero not ok?

Thanks,
/Bruce
