* rt2x00: Fix quality/activity led handlingIvo van Doorn2008-05-01
| | | | | | | | | | | | | | There was an obvious typo in LED structure initialization which caused the radio and quality/activity leds to be incorrectly initialized which resulted in the leds not being enabled. Additionally add the rt2x00led_led_activity() handler that will enable TX/RX activity leds when the radio is being enabled. Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W.

* rt2x00: Don't enable short preamble for 1MBsIvo van Doorn2008-05-01

* iwlwifi: fix debug messages during scanningBill Moss2008-05-01
| | | | | | | | | | | | | | direct_mask will be set when we are not associated and requesting a direct scan. The second debug print will be confusing as priv->essid is not set at that time and it will thus print "<hidden>" while it is known to which AP a direct scan is requested - as previous debug message also indicates. Now make all debugging consistent. Signed-off-by: Bill Moss <bmoss@clemson.edu> Signed-off-by: Reinette Chatre <reinette.chatre@intel.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

| * [netdrvr] gianfar: Determine TBIPA value dynamicallyPaul Gortmaker2008-04-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | TBIPA needs to be set to a value (on connected MDIO buses) that doesn't conflict with PHYs on the bus. By hardcoding it to 0x1f, we were preventing boards with PHYs at 0x1f from working properly. Instead, scan the bus when it comes up, and find an address that doesn't have a PHY on it. The TBI PHY configuration code then trusts that the value in TBIPA is either safe, or doesn't matter (ie - it's not an active bus with other PHYs).

This poses a problem for RDS, which uses ib_fmr_unmap as a fence operation. RDS assumes that after issuing an unmap, the old R_Keys will be invalid for a "reasonable" period of time. For instance, Oracle processes uses shared memory buffers allocated from a pool of buffers. When a process dies, we want to reclaim these buffers -- but we must make sure there are no pending RDMA operations to/from those buffers. The only way to achieve that is by using unmap and sync the TPT. However, when the sequence count is reset on unmap, there is a high likelihood that a new mapping will be given the same R_Key that was issued a few milliseconds ago. To prevent this, don't reset the sequence count when unmapping a FMR. Signed-off-by: Olaf Kirch <olaf.kirch@oracle.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>

This class of application connection setup is called peer-to-peer. Typically once the connection is setup, _both_ sides want to send data. This patch enables supporting peer-to-peer over the chelsio RNIC by enforcing this iWARP requirement in the driver itself as part of RDMA connection setup. Connection setup is extended, when the peer2peer module option is 1, such that the MPA initiator will send a 0B Read (the RTR) just after connection setup. The MPA responder will suspend SQ processing until the RTR message is received and reply-to. In the longer term, this will be handled in a standardized way by enhancing the MPA negotiation so peers can indicate whether they want/need the RTR and what type of RTR (0B read, 0B write, or 0B send) should be sent. This will be done by standardizing a few bits of the private data in order to negotiate all this. However this patch enables peer-to-peer applications now and allows most of the required firmware and driver changes to be done and tested now. Design: - Add a module option, peer2peer, to enable this mode. - New firmware support for peer-to-peer mode: - a new bit in the rdma_init WR to tell it to do peer-2-peer and what form of RTR message to send or expect. - process _all_ preposted recvs before moving the connection into rdma mode. - passive side: defer completing the rdma_init WR until all pre-posted recvs are processed. Suspend SQ processing until the RTR is received. - active side: expect and process the 0B read WR on offload TX queue. Defer completing the rdma_init WR until all pre-posted recvs are processed. Suspend SQ processing until the 0B read WR is processed from the offload TX queue. - If peer2peer is set, driver posts 0B read request on offload TX queue just after posting the rdma_init WR to the offload TX queue. - Add CQ poll logic to ignore unsolicitied read responses.
