UDP datagram should not be larger than the MTU (1500 bytes), ASIO wouldn't care and return EMSGSIZE I think.
man 7 udp
By default, Linux UDP does path MTU (Maximum Transmission Unit) discovery.
This means the kernel will keep track of the MTU to a specific target IP
address and return EMSGSIZE when a UDP packet write exceeds it. When this
happens, the application should decrease the packet size. Path MTU discov-
ery can be also turned off using the IP_MTU_DISCOVER socket option or the
/proc/sys/net/ipv4/ip_no_pmtu_disc file; see ip(7) for details. When
turned off, UDP will fragment outgoing UDP packets that exceed the inter-
face MTU. However, disabling it is not recommended for performance and re-
liability reasons.
