However, the netdev lock has already been\nacquired before ndo_bpf is called because GVE supports queue management\nops. Calling the unlocked versions of napi_disable/enable results in a\ndeadlock when attempting to disable XSK pools, as the thread attempts to\nre-acquire a lock it already holds.\n\nUpdate the NAPI calls to use the locked versions.\n\nThis issue was found in production."
