Subject: netdev-linux: Rename "linux_netdev_*" to "rtnetlink_*".
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=46097491e4ab6b957bb11690d86df24af19b5655;p=openvswitch

netdev-linux: Rename "linux_netdev_*" to "rtnetlink_*".

It was getting to be too confusing to have both netdev_linux_* functions
and linux_netdev_* functions.  Rename the latter to make the distinction
more obvious.  "rtnetlink" seems to be a fairly good name because that's
what the kernel calls it, so the name will be familiar at least to people
who know about rtnetlink.
