Subject: datapath: Add version check for struct netdev_ops.
X-Git-Tag: v1.3.0~80
X-Git-Url: http://git.onelab.eu/?a=commitdiff_plain;h=4bfff3c8b608bf174e2accd39f7c56d8f827bf2b;p=sliver-openvswitch.git

datapath: Add version check for struct netdev_ops.

Linux 3.1 drops the symbol HAVE_NET_DEVICE_OPS that lets us know
whether struct netdev_ops is present.  As a result, we need to
replace it with an explicit version check.
