Patch 1 removes the config menu for NET_LL_RX_POLL and defaults to y. Patch 2 converts sysctl_net_ll_poll into an unsigned int Patch 3 adds an SO_LL socket option to allow per-socket control of busy polling. I will reply to this thread with a patch to sockperf that enables the socket option. Thanks, Eliezer Change log: v2 - added a patch to convert sysctl_net_ll_poll into an unsigned int. - suggested by Eric Dimazet: treat sk_ll_usec as a u_int rather than a u_long. - suggested by Ben Huchings: allow unprivileged user to decrease SO_LL value, correct return value when operation is not allowed.
