Hi,

If there's no functional impact what we want to achieve
through this patch? What's the point of touching
the code which works for ages in that case?

While reading the ixgbevf_set_ringparam function, I noticed that
tx_ring is allocated using vmalloc_array(), but rx_ring still use vmalloc().

I found that commit 4490d075c2d9 ("eth: intel: use vmalloc_array() to
simplify code") didn't completely make the change. I saw a similar fix upstream
in commit 1772b7f8045b ("media: pt1: use vmalloc_array to simplify code"),
so I'm trying to make this consistent here.
