Hi all,
I add that in kernel space SDP debug the error is:
command line: dmesg sdp_init_qp:95 sdp_sock( 2100:2 40720:0): recv sge's. capability: 4 needed: 9 sdp_init_qp:95 sdp_sock( 2100:2 41203:0): recv sge's. capability: 4 needed: 9
The structure sdp_init_qp() is defined in /usr/src/ofa_kernel-1.5.1/drivers/infiniband/ulp/sdp/sdp_cma.c (lines 76 - 141).
Could be a firmware problem? I have this situation: command line: ethtool -i eth2 driver: iw_nes version: 1.5.0.0 firmware-version: 3.16 bus-info: 0000:03:00.0
Thank you very much, Andrea Andrea Gozzelino
