-====== 3 The network driver can not be loaded after the kernel's update ======
-{{indexmenu_n>3}}
-. In case your network driver can not be loaded after the kernel's update, you can try to resolve the issue by yourself:
-<code>
-ls /lib/modules/`uname -r`/extra
-</code>
-If kernel modules pf_ring.ko and igb.ko (or ixgbe.ko for 10G cards) are not present in this directory, please copy them from the similar directory of the previous kernel version: <code>find /lib/modules -name pf_ring.ko
-cd path_found
-cp pf_ring.ko /lib/modules/`uname -r`/extra
-cp igb.ko /lib/modules/`uname -r`/extra # or ixgbe</code> and execute these instructions:
-<code>
-depmod -a
-modprobe pf_ring
-modprobe igb # or modprobe ixgbe
-</code>
-. If your network card supports bypass functionality: you need to recover the bypass driver as well.
-To find the driver:
-<code>
-find /lib/modules -name bpctl_mod\*
-</code>
-Copy it to extra:
-<code>
-cp bpctl_mod.ko /lib/modules/`uname -r`/extra
-depmod -a
-</code>
-To verify operation:
-<code>
-bpctl_start
-bpctl_util all get_bypass
-</code>
-Please contact tech support if these steps do not help.
