net: ena: xdp: XDP_TX: fix memory leak
When sending very high packet rate, the XDP tx queues can get full and start dropping packets. In this case we don't free the pages which results in ena driver draining the system memory. Fix: Simply free the pages when necessary. Fixes: 548c4940b9f1 ("net: ena: Implement XDP_TX action") Signed-off-by: Sameeh Jubran <sameehj@amazon.com> Signed-off-by: David S.
