RDS: TCP: Hooks to set up a single connection path

2016-07-01T20:45:17+00:00

This patch adds ->conn_path_connect callbacks in the rds_transport
that are used to set up a single connection path.

RDS: Rework path specific indirections

2016-07-01T20:45:17+00:00

Refactor code to avoid separate indirections for single-path
and multipath transports. All transports (both single and mp-capable)
will get a pointer to the rds_conn_path, and can trivially derive
the rds_connection from the ->cp_conn.

Several cases of overlapping changes, except the packet scheduler
conflicts which deal with the addition of the free list parameter
to qdisc_enqueue().

RDS: Pass rds_conn_path to rds_send_xmit()

2016-06-15T06:50:43+00:00

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()

RDS: split out connection specific state from rds_connection to rds_conn_path

2016-06-15T06:50:41+00:00

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.

RDS: fix endianness for dp_ack_seq

2016-04-16T23:01:05+00:00

dp->dp_ack_seq is used in big endian format. We need to do the
big endianness conversion when we assign a value in host format
to it.

RDS: IB: Support Fastreg MR (FRMR) memory registration mode

2016-03-02T19:13:19+00:00

Fastreg MR(FRMR) is another method with which one can
register memory to HCA. Some of the newer HCAs supports only fastreg
mr mode, so we need to add support for it to have RDS functional
on them.

RDS: IB: allocate extra space on queues for FRMR support

2016-03-02T19:13:19+00:00

Fastreg MR(FRMR) memory registration and invalidation makes use
of work request and completion queues for its operation. Patch
allocates extra queue space towards these operation(s).

RDS: IB: Remove the RDS_IB_SEND_OP dependency

2016-03-02T19:13:17+00:00

This helps to combine asynchronous fastreg MR completion handler
with send completion handler.

No functional change.
