bnx2i Driver

The current version of the driver has been tested on 2.6.x kernels, starting from 2.6.18 kernel. The driver may not compile on older kernels with the exception of SLES 10 SP1, which runs 2.6.16.46 kernel. SUSE upgraded the iscsi_transport kernel module in SLES 10 SP1. In addition, Broadcom iSCSI offload initiators is supported on SLES 10 SP1. Testing is concentrated on i386 and x86_64 architectures, Red Hat EL5, and SUSE 10 SP1 distributions.

Packaging The Linux driver is released in the packaging formats shown in Table 3. The netxtreme2 package contains the bnx2 (1 Gb network adapter) and drivers for source RPM and compressed tar.
