+Subject: netxen: revert jumbo ringsize
+Acked-by: Karsten Keil <kkeil@novell.com>
+Reference: bnc#472416
+
+Reducing jumbo ring size below 1024 reduces throughput for old
+firmwares (3.4.216 and older) running on older (NX2031) chip,
+so restore it back to 1024.
+
+This was reduced in commit 32ec803348b4d5f1353e1d7feae30880b8b3e342
+("netxen: reduce memory footprint").
+
+Raising jumbo ring size from 512 to 1024, adds ~4MB per port, but
+there's still big saving because of original patch (~20MB per port).
