the steps mentioned below:
i. Download the kernel source package and extract it.

[root@host~]# make oldconfig
iii. The above command will create a configuration file .config in the same location. Edit the file
and enable the following parameters:
CONFIG_NET_VENDOR_CHELSIO=y
CONFIG_INFINIBAND=y
iv. Compile the kernel.
v. During kernel compilation, please ensure that the following parameters are set as follows:
CONFIG_CHELSIO_T1=m
CONFIG_CHELSIO_T1_1G=y
CONFIG_CHELSIO_T3=m
CONFIG_CHELSIO_T4=m
CONFIG_CHELSIO_T4VF=m
CONFIG_INFINIBAND_USER_MAD=m
CONFIG_INFINIBAND_USER_ACCESS=m
CONFIG_INFINIBAND_USER_MEM=y
CONFIG_INFINIBAND_CXGB3=m
CONFIG_INFINIBAND_CXGB3_DEBUG=y
CONFIG_INFINIBAND_CXGB4=m
CONFIG_SCSI_CXGB3_ISCSI=m
CONFIG_SCSI_CXGB4_ISCSI=m
vi. Install the kernel.

All driver debug data is stored in debugfs, which will be mounted in most cases. If not, mount it
manually using:
