Change 133058 by swise at swise:vic10:iwarp on 2008/01/11 17:47:09
Set the max_qp_init_rd_atom attribute in query_device
The device attribute max_qp_init_rd_atom is not getting set
in cxgb3's query_device method. Version 1.0.4 of librdmacm
now validates the user's requested initiator and responder
resources against the max supported by the device. Since
iw_cxgb3 wasn't setting this attribute (and it defaulted
to 0), all rdma_connect()s fail if there are initiator
resources requested by the app. Fix this by setting the
correct value in iwch_query_device().
