From 0f9b232b176d5cf279fc945addf1e768571b35b3 Mon Sep 17 00:00:00 2001 From: Don Skidmore Date: Tue, 18 Nov 2014 09:35:08 +0000 Subject: ixgbe: add support for X550 extended RSS support The new X550 family of MAC's will have a larger RSS hash (16 -> 64). It will also support individual VF to have their own independent RSS hash key.
