// MaxAckFrameSize is the maximum size for an (IETF QUIC) ACK frame that we write
// Due to the varint encoding, ACK frames can grow (almost) indefinitely large.
// The MaxAckFrameSize should be large enough to encode many ACK range,
// but must ensure that a maximum size ACK frame fits into one packet.

// MinPacingDelay is the minimum duration that is used for packet pacing
// If the packet packing frequency is higher, multiple packets might be sent at once.
// Example: For a packet pacing delay of 20 microseconds, we would send 5 packets at once, wait for 100 microseconds, and so forth.
