From: Adrien Mazarguil Date: Thu, 21 Mar 2013 10:09:23 +0000 (+0100) Subject: kni: fix build with kernel < 3.3 with netdev_features_t backport X-Git-Tag: spdx-start~10927 X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=205c33c45af62349fcbfa700c7cf5d2b32973498;p=dpdk.git kni: fix build with kernel < 3.3 with netdev_features_t backport The netdev_features_t typedef appeared in Linux 3.3, but checking the kernel version isn't enough with some distributions (such as Debian Wheezy) that backported it into 3.2, causing a compilation failure due to redefinition. Since the presence of a typedef can't be tested at compile time, this commit adds type kni_netdev_features_t, which, depending on the kernel version, translates either to u32 or netdev_features_t.
