NetXtreme-C/NetXtreme-E
User Guide
NOTE:
It is necessary to load the correct bnxt_en version that is included in the same netxtreme-bnxt_en-1.7.x.tar.gz
package. Bnxt_re and Bnxt_en function as a pair to enable RoCE traffic. Using mismatching versions of these two
drivers produces unreliable or unpredictable results.
Distros that have an IB Stack available along with OS distribution:
RH7.1/7.2/7.3/6.7/6.8, SLES12SP2 and Ubuntu 16.04
If not already installed, the IB stack and useful utils can be installed in Redhat with the following commands prior to
compiling bnxt_re:
yum -y install libibverbs* inifiniband-diag perftest qperf librdmacm utils
To compile bnxt_re:
$make
Distros that need external OFED to be installed:
SLES11SP4
Refer to the OFED release notes at the following link and install OFED before compiling bnxt_re driver.
http://downloads.openfabrics.org/downloads/OFED/release_notes/OFED_3.18-2_release_notes
To compile bnxt_re:
$export OFED_VERSION=OFED-3.18-2
$make
