The only two differences that were really left between Netdev and NetLegacy: 1) NetLegacy does not allow a "hubport" type. We can continue to block this with a simple check in net_client_init1() for this type. 2) The "id" parameter was optional in NetLegacy (and an internal id was chosen via assign_name() during initialization), but it is mandatory for Netdev. To avoid that the visitor code bails out here, we have to add an internal id to the QemuOpts already earlier now. Signed-off-by: Thomas Huth --- Note: I did not rename the "is_netdev" parameter of the function (as Eric suggested) - you really have to think of "-netdev" vs. "-net" here and not about "Netdev" vs. "NetLegacy". But if this "is_netdev" thing still confuses us in the future, we can still rename it with an additional follow-up patch later instead. net/net.c | 77 +++++++++------------------------------------------ qapi/net.json | 46 ------------------------------ 2 files changed, 13 insertions(+), 110 deletions(-) diff --git a/net/net.c b/net/net.c index a24da66e66..d4cc5bd73e 100644 --- a/net/net.c +++ b/net/net.c @@ -965,15 +965,11 @@ static int (* const net_client_init_fun[NET_CLIENT_DRIVER__MAX])( };
