[PATCH] ipoib: Fix lockup of the tx queue

2010-03-03 Thread Eli Cohen
The ipoib UD QP reports send completions to priv-send_cq which is unarmed generally; it only gets armed when the number of outstanding send requests (e.g. those for which a completion was not polled yet) reaches the size of the tx queue. This arming (done using ib_req_notify_cq()) is done only in

[PATCH] RDMA/cxgb3: wait at least one schedule cycle during device removal.

2010-03-03 Thread Steve Wise
During a hot-plug LLD removal event or an EEH error event, iw_cxgb3 must ensure that any/all threads that might be in a cxgb3 exported function concurrently must return from the function before iw_cxgb3 returns from its event processing. Do this by calling synchronize_net(). Signed-off-by: Steve

Setting QP attributes with RDMA CM

2010-03-03 Thread Todd Strader
Hi, I'm using the RDMA CM to set up a QP and I'm trying to figure out if I can suggest QP attributes to it before it transitions through all the states. My QP is coming up with rnr_retry = 0, and I'd like to set it higher. Is there any way to do this besides going back through RTR - RTS?

Mike- A number of fixes related to ipv6 address resolution by rdma_cm went in to ofed 1.5.1 that may be related to this. You may want to test 1.5.1 and see if it resolves your issue. As I recall link-local address are treated different that assigned ipv6 address so you might want to try using

I've applied the patch and initial testing has not produced any transmit timeout errors. I'll be doing some heavier testing in the next couple days, but it looks good so far. Thanks for the quick turn-around! -JE On Wed, Mar 3, 2010 at 4:29 AM, Eli Cohen e...@dev.mellanox.co.il wrote: I just
