Member Data Documentation

subscriptions

std::vector<DatagramSubscription> fastmm::net::KernelSourceConfig::subscriptions

line = index, at most 256

rcvbuf_bytes

int fastmm::net::KernelSourceConfig::rcvbuf_bytes = 0

0 keeps the system default

batch

std::uint32_t fastmm::net::KernelSourceConfig::batch = 32

datagrams per recvmmsg, 1..1024

max_datagram

std::uint32_t fastmm::net::KernelSourceConfig::max_datagram = 2048

larger datagrams are dropped (truncated)

timestamps

bool fastmm::net::KernelSourceConfig::timestamps = true

SO_TIMESTAMPING.

busy_poll

bool fastmm::net::KernelSourceConfig::busy_poll = false

SO_BUSY_POLL / SO_PREFER_BUSY_POLL / SO_BUSY_POLL_BUDGET on every socket.

Failures do not fail open(); they are reported in KernelSourceOpen.

busy_poll_usec

int fastmm::net::KernelSourceConfig::busy_poll_usec = 50

busy_poll_budget

int fastmm::net::KernelSourceConfig::busy_poll_budget = 0

0 keeps the kernel default (8)
