Descriptions

In the Linux kernel, the following vulnerability has been resolved: octeontx2-af: Fix mcam entry resource leak The teardown sequence in FLR handler returns if no NIX LF
is attached to PF/VF because it indicates that graceful
shutdown of resources already happened. But there is a
chance of all allocated MCAM entries not being freed by
PF/VF. Hence free mcam entries even in case of detached LF.
