rds_conn_path_connect_if_down() works on the rds_conn_path that it is passed. Callers who are not t_m_capable may continue calling rds_conn_connect_if_down, which will invoke rds_conn_path_connect_if_down() with the default c_path[0]. Signed-off-by:

This commit allows rds_send_pong() callers to send back the rds pong message on some path other than c_path[0] by passing in a struct rds_conn_path * argument. It also removes the last dependency on the #defines in rds_single.h from send.c Signed-off-by:

Pass a struct rds_conn_path to rds_send_xmit so that MP capable transports can transmit packets on something other than c_path[0]. The eventual goal for MP capable transports is to hash the rds socket to a path based on the bound local address/port, and use this path as the argument to rds_send_xmit() Signed-off-by:

Pass the rds_conn_path to rds_send_queue_rm, and use it to initialize the i_conn_path field in struct rds_incoming. This commit also makes rds_send_queue_rm() MP capable, because it now takes locks specific to the rds_conn_path passed in, instead of defaulting to the c_path[0] based defines from rds_single_path.h Signed-off-by:

In preparation for multipath RDS, split the rds_connection structure into a base structure, and a per-path struct rds_conn_path. The base structure tracks information and locks common to all paths. The workqs for send/recv/shutdown etc are tracked per rds_conn_path. Thus the workq callbacks now work with rds_conn_path. This commit allows for one rds_conn_path per rds_connection, and will be extended into multiple conn_paths in subsequent commits. Signed-off-by:

Make sure that dctcp_get_info() returns only the size of the info->dctcp struct that it zeroes out and fills in. Previously it had been returning the size of the enclosing tcp_cc_info union, sizeof(*info). There is no problem yet, but that union that may one day be larger than struct tcp_dctcp_info, in which case the TCP_CC_INFO code might accidentally copy uninitialized bytes from the stack.

Merge tag 'rxrpc-rewrite-20160613' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs David Howells says: ==================== rxrpc: Rename rxrpc source files Here's the next part of the AF_RXRPC rewrite. In this set I rename some of the files in the net/rxrpc/ directory and adjust the Makefile and ar-internal.h to reflect the changes. The aim is twofold: (1) Remove the "ar-" prefix on those files that have it as it's not really useful, especially now that I'm building rxkad in. (2) To aid splitting the local, peer, connection and call handling code into separate files for object and event handling in future patches by making it easier to come up with new filenames. There are two commits: (1) The first commit does a bunch of renames of .c files and alters the Makefile. ar-internal.h isn't renamed at this time to avoid having to change the contents of the files being renamed. (2) The second commit changes the section label comments in ar-internal.h to reflect the changed filenames and reorders the file so that the sections are back in filename order. The patches can be found here also: http://git.kernel.org/cgit/linux/kernel/git/dhowells/linux-fs.git/log/?h=rxrpc-rewrite Tagged thusly: git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs.git rxrpc-rewrite-20160613 ==================== Signed-off-by:

Move the settings of PHY to a work queue and schedule it after rtl_ops.init(). There are some reasons for this. First, the settings are only needed for the first time initialization or after the power down occurs. Second, the settings are independent with the others. Last, the settings may take more time than the others. Leave they in probe() or open() may delay the following flows. Signed-off-by:

The PF can setup a default VLAN for a VF. The default VLAN tag is automatically inserted and stripped without the knowledge of the stack running on the VF. The VF driver needs to know that default VLAN is enabled as VLAN acceleration on the RX side is no longer supported. Call netdev_update_features() to fix up the VLAN features as necessary. Also, VLAN strip mode must be enabled to strip out the default VLAN tag. Only allow VF default VLAN to be set if the firmware spec is >= 1.2.1. Signed-off-by:

The commit e858fae2 ("virtio_net: use common code for virtio_net_hdr and skb GSO conversion") replaced the tun code for header manipulation with the generic helpers. While doing so, it implictly moved the skb_partial_csum_set() invocation after eth_type_trans(), which invalidate the current gso start/offset values. Fix it by moving the helper invocation before the mac pulling. Fixes: e858fae2 ("virtio_net: use common code for virtio_net_hdr and skb GSO conversion") Reported-by:

Rename files matching net/rxrpc/ar-*.c to get rid of the "ar-" prefix. This will aid splitting those files by making easier to come up with new names. Note that the not all files are simply renamed from ar-X.c to X.c. The following exceptions are made: (*) ar-call.c -> call_object.c ar-ack.c -> call_event.c call_object.c is going to contain the core of the call object handling. Call event handling is all going to be in call_event.c. (*) ar-accept.c -> call_accept.c Incoming call handling is going to be here. (*) ar-connection.c -> conn_object.c ar-connevent.c -> conn_event.c The former file is going to have the basic connection object handling, but there will likely be some differentiation between client connections and service connections in additional files later. The latter file will have all the connection-level event handling. (*) ar-local.c -> local_object.c This will have the local endpoint object handling code. The local endpoint event handling code will later be split out into local_event.c. (*) ar-peer.c -> peer_object.c This will have the peer endpoint object handling code. Peer event handling code will be placed in peer_event.c (for the moment, there is none). (*) ar-error.c -> peer_event.c This will become the peer event handling code, though for the moment it's actually driven from the local endpoint's perspective. Note that I haven't renamed ar-transport.c to transport_object.c as the intention is to delete it when the rxrpc_transport struct is excised. The only file that actually has its contents changed is net/rxrpc/Makefile. net/rxrpc/ar-internal.h will need its section marker comments updating, but I'll do that in a separate patch to make it easier for git to follow the history across the rename. I may also want to rename ar-internal.h at some point - but that would mean updating all the #includes and I'd rather do that in a separate step. Signed-off-by:
