firmware,IB/qib: revert firmware file move

2013-04-05T19:19:39Z

Commit e2eed58b4fbf ("IB/qib: change QLogic to Intel") moved a firmware file potentially breaking the ABI. This patch reverts that aspect of the fix as well as reverting the firmware name as used in qib. Reported-by: David Woodhouse Signed-off-by: Mike Marciniszyn Signed-off-by: Linus Torvalds

IB/ipath: Silence a static checker warning

2013-03-23T01:07:04Z

I have a static checker which complains that 0x255 is too high for the "dev->opstats[opcode]" array. It turns out that the hardware has already validated the opcode at this point so it can't actually overflow. However, silencing the warning is good and this matches how the opcode is treated in qib_ib_rcv() as well. Signed-off-by: Dan Carpenter Acked-by: Mike Marciniszyn Signed-off-by: Roland Dreier

IPoIB: Fix send lockup due to missed TX completion

2013-03-23T01:01:04Z

Commit f0dc117abdfa ("IPoIB: Fix TX queue lockup with mixed UD/CM traffic") attempts to solve an issue where unprocessed UD send completions can deadlock the netdev. The patch doesn't fully resolve the issue because if more than half the tx_outstanding's were UD and all of the destinations are RC reachable, arming the CQ doesn't solve the issue. This patch uses the IB_CQ_REPORT_MISSED_EVENTS on the ib_req_notify_cq(). If the rc is above 0, the UD send cq completion callback is called directly to re-arm the send completion timer. This issue is seen in very large parallel filesystem deployments and the patch has been shown to correct the issue.

Fix dst_neigh_lookup/dst_neigh_lookup_skb return value handling bug

2013-03-15T13:06:58Z

When neighbour table is full, dst_neigh_lookup/dst_neigh_lookup_skb will return -ENOBUFS which is absolutely non zero, while all the code in kernel which use above functions assume failure only on zero return which will cause panic. (for example: : https://bugzilla.kernel.org/show_bug.cgi?id=54731).
