Subject: [PATCH] tools: support binding to built-in kernel modules
|
|
|
|
Currently dpdk_nic_bind.py detects Linux kernel modules via reading
|
|
/proc/modules. Built-in ones aren't listed there and therefore they are
|
|
not being found by the script.
|
|
|
|
Add support for checking built-in modules with parsing the sysfs files.
|
|
|
|
This commit obsoletes the /proc/modules parsing approach.
