From 8fc3bb6daab26e0c40c19040208091f140b6f8d5 Mon Sep 17 00:00:00 2001 From: Emil Tantilov Date: Tue, 8 Jan 2013 04:23:53 +0000 Subject: [PATCH] ixgbe: refactor initialization of feature flags This patch reshuffles the switch/case structure of the flag assignment to allow for the flags to be set for each MAC type separately. This is needed for new HW that does not have feature parity with older HW.
