IB/core: Fix IB_SA_COMP_MASK macro

2012-05-19T00:16:11Z

It needs parentheses around the argument, so that it can be used with complex arguments (e.g., "n+5"). Signed-off-by: Jack Morgenstein Signed-off-by: Roland Dreier

IB/core: Add raw packet QP type

2012-05-08T18:18:09Z

IB_QPT_RAW_PACKET allows applications to build a complete packet, including L2 headers, when sending; on the receive side, the HW will not strip any headers. This QP type is designed for userspace direct access to Ethernet; for example by applications that do TCP/IP themselves. Only processes with the NET_RAW capability are allowed to create raw packet QPs (the name "raw packet QP" is supposed to suggest an analogy to AF_PACKET / SOL_RAW sockets).

IB/core: Use qp->usecnt to track multicast attach/detach

2012-05-08T18:16:54Z

Just as we don't allow PDs, CQs, etc. to be destroyed if there are QPs that are attached to them, don't let a QP be destroyed if there are multicast group(s) attached to it. Use the existing usecnt field of struct ib_qp which was added by commit 0e0ec7e ("RDMA/core: Export ib_open_qp() to share XRC TGT QPs") to track this.

IB: Change CQE "csum_ok" field to a bit flag

2012-03-08T20:34:27Z

Use a bit in wc_flags rather then a whole integer to hold the "checksum OK" flag. By itself, this change doesn't reduce the size of struct ib_wc on 64bit machines -- it stays on 56 bytes because of padding. However, it will allow to add more fields in the future without enlarging the struct. Also, it will let us have a unified approach with future libibverbs checksum offload reporting, because a bit flag doesn't break the library ABI. This patch was suggested during conversation with Liran Liss . Signed-off-by: Or Gerlitz Reviewed-by: Sean Hefty Signed-off-by: Roland Dreier

IB: Use central enum for speed instead of hard-coded values

2012-03-05T17:25:16Z

The kernel IB stack uses one enumeration for IB speed, which wasn't explicitly specified in the verbs header file. Add that enum, and use it all over the code. The IB speed/width notation is also used by iWARP and IBoE HW drivers, which use the convention of rate = speed * width to advertise their port link rate.

IB/mad: Add MAD error codes from IBA spec

2012-02-26T01:47:31Z

Add defines for MAD error codes so that they can be used when returning error responses. Signed-off-by: Swapna Thete Signed-off-by: Roland Dreier
