Subject: [NETNS][DST]: Add the network namespace pointer in dst_ops
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=d4fa26ff44e31c2636a985e3092e2cd55d8045de;p=openwrt%2Fstaging%2Fblogic.git

[NETNS][DST]: Add the network namespace pointer in dst_ops

The network namespace pointer can be stored into the dst_ops structure.
This is usefull when there are multiple instances of the dst_ops for a
protocol. When there are no several instances, this field will be never
used in the protocol. So there is no impact for the protocols which do
implement the network namespaces.
