RDMA/cxgb4: Add support for active and passive open connection with IPv6 address

2013-08-13T18:55:06+00:00

Add new cpl messages, cpl_act_open_req6 and cpl_t5_act_open_req6, for initiating active open connections. Use LLD api cxgb4_create_server and cxgb4_create_server6 for initiating passive open connections. Similarly use cxgb4_remove_server to remove the passive open connections in place of listen_stop. Add support for iWARP over VLAN device and enable IPv6 support on VLAN device. Make use of import_ep in c4iw_reconnect.

RDMA/cxgb4: Address sparse warnings

2013-02-14T23:51:58+00:00

Fixe the following types of sparse warnings - cast to pointer from integer of different size - cast from pointer to integer of different size - incorrect type in assignment (different base types) - incorrect type in argument 1 (different base types) - cast from restricted __be64 - cast from restricted __be32 Signed-off-by: Vipul Pandya Signed-off-by: Roland Dreier

RDMA/cxgb4: Fix bug for active and passive LE hash collision path

2012-12-20T07:03:12+00:00

Retries active opens for INUSE errors. Logs any active ofld_connect_wr error replies. Sends ofld_connect_wr on same ctrlq. It needs to go on the same control txq as regular CPL active/passive messages. Retries on active open replies with EADDRINUSE. Uses active open fw wr only if active filter region is set. Adds stat for ofld_connect_wr failures. This patch also adds debugfs file to show endpoints. Signed-off-by: Vipul Pandya Signed-off-by: Roland Dreier

RDMA/cxgb4: Fix LE hash collision bug for passive open connection

2012-12-20T07:03:11+00:00

It establishes passive open connection through firmware work request. Passive open connection will go through this path as now instead of listening server we create a server filter which will redirect the incoming SYN packet to the offload queue. After this driver tries to establish the connection using firmware work request. Signed-off-by: Vipul Pandya Signed-off-by: Roland Dreier

RDMA/cxgb4: Remove kfifo usage

2012-05-18T20:22:36+00:00

Using kfifos for ID management was limiting the number of QPs and preventing NP384 MPI jobs. So replace it with a simple bitmap allocator. Remove IDs from the IDR tables before deallocating them. This bug was causing the BUG_ON() in insert_handle() to fire because the ID was getting reused before being removed from the IDR table.

RDMA/cxgb4: Use vmalloc() for debugfs QP dump

2012-05-18T20:22:35+00:00

This allows dumping thousands of QPs. Log active open failures of interest. Signed-off-by: Vipul Pandya Signed-off-by: Steve Wise Signed-off-by: Roland Dreier
