Some cards' drivers make more efficient use of memory than others'.
In some cases, this is because the card is faster or slower, or the
design of the hardware requires more memory to be used.  Not being a
NIC driver writer, I can't give you more details than that.

Have you tried increasing NMBCLUSTERS?  It's a kernel variable that
you'd want to tweak in your kernel config file -- see options(4).  On
busy systems, you need higher values for this variable.  It's set at a
good compromise value by default, but there are cases (like yours,
apparently) where it's not enough.

All this doesn't rule out the possibility of hardware failure, but I'd
try at least changing NMBCLUSTERS first.
