224 Busy polling
227 Busy polling allows a user process to check for incoming packets before
228 the device interrupt fires. As is the case with any busy polling it trades
229 off CPU cycles for lower latency (production uses of NAPI busy polling
232 Busy polling is enabled by either setting ``SO_BUSY_POLL`` on
234 ``net.core.busy_read`` sysctls. An io_uring API for NAPI busy polling
237 epoll-based busy polling
255 In order to enable busy polling, there are two choices:
