Subject[PATCH AUTOSEL 5.16 11/52] SUNRPC allow for unspecified transport time in rpc_clnt_add_xprt
Date
From: Olga Kornievskaia <kolga@netapp.com>

[ Upstream commit b8a09619a56334414cbd7f935a0796240d0cc07e ]

If the supplied argument doesn't specify the transport type, use the
type of the existing rpc clnt and its existing transport.
