Revision 1d5a474240407c38ca8c7484a656ee39f585399c authored by Martin Habets on 02 January 2022, 08:41:22 UTC, committed by Jakub Kicinski on 05 January 2022, 02:14:21 UTC

performance. When allocation fails the driver can still
function, but possibly with a lower bandwidth.
Guard against dereferencing a NULL page_ring.
