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

BlockingRecvMMsg 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.
