AppendIovecFromBytes returns append(iovs, IovecFromBytes(bs)).

BlockingPoll on amd64/arm64 makes the ppoll() syscall while calling the version of entersyscall that relinquishes the P so that other Gs can run.

BlockingPollUntilStopped polls for events on fd or until a stop is signalled on the event fd efd.

BlockingRead reads from a file descriptor that is set up as non-blocking.

BlockingReadUntranslated reads from a file descriptor that is set up as non-blocking.

BlockingReadvUntilStopped reads from a file descriptor that is set up as non-blocking and stores the data in a list of iovecs buffers.

BlockingRecvMMsgUntilStopped reads from a file descriptor that is set up as non-blocking and stores the received messages in a slice of MMsgHdr structures.

GetMTU determines the MTU of a network interface device.

IovecFromBytes returns a unix.Iovec representing bs.

NonBlockingSendMMsg sends multiple messages on a socket.

NonBlockingWrite writes the given buffer to a file descriptor.

NonBlockingWriteIovec writes iovec to a file descriptor in a single unix.

TranslateErrno translate an errno from the syscall package into a tcpip.Error.

MaxIovs is UIO_MAXIOV, the maximum number of iovecs that may be passed to a host system call in a single array.

SizeofIovec is the size of a unix.Iovec in bytes.

SizeofMMsgHdr is the size of a MMsgHdr in bytes.

MMsgHdr represents the mmsg_hdr structure required by recvmmsg() on linux.

PollEvent represents the pollfd structure passed to a poll() system call.
